What is battery charger?

Harmonic is a 9.6V 1.2A nicd battery charger in and one that designers of power continuity programmes and manufacturers of UPS (uninterruptible power supplies) cannot ignore. Typical harmonic problems include the distortion of mains power supply voltage, overheating of wiring, neutral conductors, supply transformers and switchgear and nuisance tripping of breakers. Harmonics can also cause disruption to equipment on the same supply and lead to random failures.

Harmonics are caused by voltage or current waveforms with frequencies that are multiples of the fundamental frequency – in Europe, 50Hz (50 cycles per second). The multiples are always ordered in a specific sequence: for example, the 2nd harmonic is 100Hz (2x50Hz), the third 150Hz and the fourth 200Hz and so on.

Harmonics and total power factor – implications for UPS sizing. Harmonics are also closely related to power factor management – and another key aspect of uninterruptible power supply system design and implementation. The displacement power factor is only applicable to the fundamental frequency (50Hz in Europe) and therefore does not take into account the power factor generated by any harmonics induced into the mains power supply by the load itself (referred to as the distortion power factor and produced by the harmonics produced by non-linear loads). The combination of the displacement power factor and the distortion power factor gives what is known to UPS systems experts as the true power factor. When correctly sizing a UPS, an understanding of this is critical.

Mitigation of total harmonics distortion. Harmonics issues need to be addressed at the design stage of any power continuity plan. Not least, because consumers are responsible for the harmonic levels introduced into their three-phase mains power supply.

A UPS can sometimes be fitted with a harmonic filter (post installation) but this can be a costly and inelegant solution as extensive internal wiring changes may be required. For a transformer-based UPS, using a 12-pulse rectifier in place of a 6-pulse set will reduce the levels of THDi (total harmonic distortion). Coupling this with a passive filter will provide further reduction to around 4%.

For a transformerless uninterruptible power supply, THDi levels of less than 4% can be achieved by installing an active harmonic filter. However, levels as low as 3% can now be achieved by some designs whose rectifiers are IGBT (Insulated Gate Bipolar Transistor) based. This can remove the need for an additional active harmonic filter and simplify the UPS design process. Such designs are expected to become the norm: not only do they reduce initial costs, but they allow a smaller UPS system footprint whilst increasing input power factors.

A popular approach to reduce the effect of leading power battery charger  factors on a UPS installation is to use an active harmonic filter with power factor correction on the UPS output. This presents the UPS with a more acceptable load, but results in higher capital and installation costs, lower efficiency and a greater footprint.

Familiar territory for UPS manufacturers. Although many aspects of harmonics must be considered when specifying a UPS system, reassurance can be gained from the fact that this is familiar territory for UPS manufacturers such as Riello UPS. End users and their professional advisers can certainly be confident that this specialised aspect of UPS application will be thoroughly addressed during the modern consultative sales and specification process.

9.6V 1.2A nicd battery charger

The charge cannot be terminated on a voltage capacity reached at 29.4V 14A lithium battery charger?

These remarks apply equally to lithium ion and lithium polymer batteries. The hemistry is basically the same for the two types of batteries, so charging methods for lithium polymer batteries can be used for lithium-ion batteries.
Charging lithium iron phosphate 3.2 volt cells is identical, but the constant voltage phase is limited to 3.65 volts.

The lithium ion battery is easy to charge. Charging safely is a more difficult. The basic algorithm is to charge at constant current (0.2 C to 0.7 C depending on manufacturer) until the battery reaches 4.2 Vpc (volts per cell), and hold the voltage at 4.2 volts until the charge current has dropped to 10% of the initial charge rate. The termination condition is the drop in charge current to 10%. The top charging voltage and the termination current varies slightly with the manufacturer.

However, a charge timer should be included for safety.

The charge cannot be terminated on a voltage. The capacity reached at 4.2 Volts per cell is only 40 to 70% of full capacity unless charged very slowly. For this reason you need to continue to charge until the current drops, and to terminate on the low current.

It is important to note that trickle charging is not acceptable for lithium batteries. The Li-ion chemistry cannot accept an overcharge without causing damage to the cell, possibly plating out lithium metal and becoming hazardous.

Importance of Standby Power Supplies to Varied Industries

Almost no industry and business today can function smoothly and record profit without a steady supply of electricity. An outage can be highly destructive and easily turn the profit books and loss wells without you even realizing how the damage was caused. Thankfully, the situated is easily averted by installing standby power supplies.

Standby power supplies are those units which immediately take over to supply uninterrupted power in case of a grid failure. A reliable secondary source of electricity, these are widely used by homes and residential blocks, small businesses and even large businesses and industries to block away all loss and inconvenience due to the unexpected power outages. These are available in large varieties with varied range of features, output capacities and dependability to suit different requirements. While these may be optional and meant for comfort in some cases like the residents and homes, but their presence is critical for many industries. Let us glimpse through some of them.

The health industry

Life is the most precious gift awarded to mankind and it is thoroughly dependent on electricity while in a hospital. All the laboratories tests that are done in a laboratory mostly require electricity. Moreover patients in the ICU and other wards are often put on machines run on electricity. A minute of power outage may just equate to death for many patients which cannot be recovered at any costs. Thus an alternate source of power here is critical.

Data Centers

Many few realize how the data driven world of today has impacted our power needs. From small offices to big infrastructure industries, all work accounts, management information, analysis, employee information, salary and all aspects depending upon specific industry are working on computers. A sudden power outage might imply a sudden shut down of the computer and loss of vital data and information. Even a minute of computer shutdown can lead to loss in millions! A standby power supply is a must.

Various Industries

There are many industries like tea, lumbering, iron and steel etc. which have heavy machines running on electricity. Sudden power outage would mean these machines coming to a halt and the entire production line going for a toss. This amounts to a huge loss financially, manpower wise, productivity and even credibility and profitability. Investing in an alternate power supply as a standby is a much cheaper and smart action to take.

Hospitality Industry

Most restaurants and those associated with hospitality industry have cold storage to store fruits, vegetables, meat and all other possible items that may get destroyed unless cold stored. The spoiled food and wine in case of a power outage cannot be recovered back under any circumstances. Again while preparing the food electricity is used by various gadgets like mixer, oven, OTG, exhaust fan and even electric burners etc. Preparing the food and serving customers can be impossible without electricity. Further, no customers can eat in darkness or live in a hotel without electricity. Alternate power supply is a must have.

Every industry has unique needs which make opting for camera power supply unit a necessity and not an optional choice.

How to Fix Toshiba PA3237U-1ACA AC Adapter power cord wire

If one of the wires of your Toshiba PA3237U-1ACA AC Adapter laptop power cord is damaged, you may be able to repair it yourself. Before attempting any repair, however, check your manufacturer's or extended warranty on your laptop. Repairing the Toshiba AC Adapter power supply wire yourself will definitely void any warranty on the laptop ac adapter power supply.

Here is the brief Instructions on how to Fix Toshiba PA3237U-1ACA AC Adapter wire:

Cut out the entire damaged portion of wire from your Toshiba PA3237U-1ACA AC Adapter power supply, cutting straight across both wires on either side of the damage to remove a complete section of cord. If the wires inside the remaining Toshiba AC Adapter cord look blackened, cut out more until you see bright copper or aluminum wire.

Slice between the two wires on the cord gently to separate the insulation that holds them together. Be careful not to damage the individual insulation on each Toshiba PA3237U-1ACA AC Adapter wire. Cut off the outer insulation surrounding the last inch of wire on each side of the cut. Strip the individual wire insulation off the last 1/4-inch of each wire on both sides of the cut. Cut a 2 1/2-inch-long piece of shrink tube big enough to fit over the outer insulation loosely, and slip it over the ends of the longer portion of wire, sliding it down the cord until it is out of your way for working with the laptop ac adapters wires.

Place one stripped end of the Toshiba PA3237U-1ACA AC Adapter wire all the way into your barrel connector, until the insulation meets the place where the barrel narrows and the bare wire tips are at the center of the connector. Squeeze the connector tightly shut with a crimping tool. Find the Toshiba AC Adapter wire that your first wire connected to before you cut out the damaged section and place it into the other end of the crimp. Squeeze the crimp shut.

Pull firmly on both Toshiba PA3237U-1ACA AC Adapter wires. If one comes out, remove the crimp from both (you may have to trim back your wires to cut it off) and start with a fresh crimp.Repeat the process for the second laptop ac adapter wire. Slide the shrink tube up over the connection until it is completely covered. Apply heat to the shrink tube with a heat gun until it shrinks to fit snugly against the Toshiba PA3237U-1ACA AC Adapter wires and connectors.

What is Switch Mode Power Supply?

Every electrical or electronic device needs power for work and the computer is not exception to it. Computers, too, have a particularly designed power supply component known as Switch Mode Power Supply. SMPS converts raw input power to controlled voltage and current for the operation of various components of the computer. SMPS uses switches for high efficiency. The primary function of SMPS is to convert the alternating current (AC) power available in homes into direct current (DC) required for a computer system. In desktop computers, a metal box found in the corner of the CPU case supplies
power to various components in the CPU box. The power supply converts 115-230 volt AC into DC that is required for computer components to work.

The terms such as voltage, AC, DC, etc., are closely associated with the power supply or SMPS. Voltage is an electric potential difference between two points and is measured in volts. AC stands for alternating current. It is an electric
current whose magnitude and direction vary cyclically. DC stands for direct current. It is considered as the constant flow of electrons in a single direction from low to high potential. Computers use DC power. Because of the advantage of alternating current over direct current in transforming and transmission, electric power distribution today is nearly everywhere alternating current.

power supply specification does not support the -5V compatibility voltage and, therefore, should not be used with motherboards that have ISA slots.

The Lifeline For Ensuring Continuous Power Supply

UPS is life saviour of your equipment as well as provides smooth and uninterrupted work flow. Besides providing the constant power Supply during power failure, it has other benefits as stated below.

Continuity of Operation:
The greatest benefit of installation of UPS is that it provides continuity of the work without disturbance. Just imagine, if you are in the middle of some important work or about to finish, your work comes to a standstill with impulsive power failure.

Thus, UPS has become an integral part and essential whether it is corporate office or your home. The time factor of temporary power depends on the UPS battery. The more the battery rating, there is more backup time, which in turn gives sufficient time for you to finish your work.

Power Fluctuation:
There are cases wherein the electronic equipment failure occurs due to improper voltage or sudden spike in the circuit. UPS regulates the voltage and protects the equipment from spikes and voltage fluctuation whether it is high voltage or low voltage. UPS controls the output power and keeps your electronic equipment safe and working thereby protecting them major breakdown and failure.

Surge Protection:
The modern day electronic equipment is very sensitive to power. It requires good quality of power supply to function better. Due to frequent surges in the power supply, there are higher chances of your equipment failure. Hence UPS plays a vital role in surge protection and outrages.

Prevents data loss:
The risk of computers failure increases if they are not shutdown in proper manner. If your computer fails, you are at big loss resulting to irrecoverable data loss. If you are in the middle of taking backup and sudden power failure occurs, it will disrupt the process and might cause permanent damage to your important data. By having UPS, you get the time to shut down the necessary activities after the process is completed, and thereby preventing data loss.

Maintains battery charge:
Most of the today's generation are online UPS wherein the batteries are constantly charged. The internal circuit senses the input power and if it does sense the power, it switches to battery source and thereby provides constant power output. Once the power is restored, the battery gets charged automatically eliminating the need to charge it again manually. Though this type of UPS are little bit expensive but not expensive when compared to data loss or critical equipment failure.

Monitoring electrical parameters:
There are UPS Security Camera Power Supply systems which come with in-built electrical monitoring system. This enables you to monitor the input power, output power and other important parameters. If there is any fluctuation in the input source, it shows alarm to rectify the faults immediately thereby preventing major loss.

Tips on replacing your laptop ac adapter

laptops operate off of direct current (DC) energy. Standard household jacks, and almost all businesses in the US make use of alternating (AC) current. This means that all PCs need a special adapter (power supply) that will temporarily store a charge from the AC current to provide an even flow of energy to the DC input jack. These power supplies are composed of a multi-wire cord connecting to an AC/DC adapter, which then has a single direct-current cord that leads to the laptops DC input jack. If your laptop has trouble charging, or the light on your AC/DC adapter does not turn on, it has to be replaced.

Use the Internet to select the proper AC adapter for your notebook. And you can find a wide variety of brand laptop AC adapters here at  Hootoo.com.

Secondly, Use the information you get from the Internet search to buy the proper replacement power supply. The best deals are typically online or direct from the manufacturers, but it is more convenient to go to a retail store to get a replacement part immediately.

Disconnect your old power supply from the laptop. This includes the entire power cable and AC/DC adapter. You may be able to reuse the cords of your old unit, such as if they are longer.

Assemble the new power supply that you purchased earlier. The AC cord connects to the AC/DC adapter, which connects to the DC cord, which finally connects to the laptop.

Check the light on the AC/DC adapter is lit. This indicates that the power supply is receiving power. You should also check your Windows desktop in the lower right hand toolbar for a power charging icon; it will look like a battery with a lightning bolt flashing on it.

Types and Uses of Universal Power Cord

Last week I visited my friends home and forgot to carry my laptop charger while packing.So after working a while, my laptop's battery went down and I needed a power cable. That's when my friend came to rescue and gave me the most useful thing ever, a 'Universal power cord'.

Universal Power cords or adpaters, as commonly known as are devices that make it possible to connect a power supply to various devices in just about any setting. There are adapters for handheld devices, laptops, and even for various types of household appliances. The need for a universal power adapter usually comes about when an individual is traveling to another country, where the type of electrical outlets and the kind of power supply must be converted in order to function properly with the device.

One of the more common examples of a universal power adapter would be the universal laptop power adapter. Adapters of this type normally come with plug attachments that make it possible to connect the power cord to different configurations of wall outlets. Since various countries use different designs and standards for electrical outlets, anyone who travels to a foreign location is likely to need these attachments in order to be able to use the laptop without relying solely on battery power.

Along with making sure that the plugs are compatible, a true universal power adapter will also help to convert the type of current available within the country to a type that is compatible with the electronic device. For example, if a handheld device or laptop requires direct current to operate properly, but the individual is traveling in a where alternating current is the norm, the adapter will  for the difference in voltage and cycle of the electrical current. This makes it possible to use the device without damaging the parts.

Along with adapters for use by travelers, people who are living abroad for a period of time may also make use of a universal power adapter on any household appliance he or she is taking along. Adapters of this type can be used with stereo equipment or other expensive electrical items that the individual wishes to have access to on an ongoing basis. When purchasing adapters for this purpose, it is important to make sure the particular appliance will function properly with an adapter, since some electrical appliances will not work at full efficiency even with the use of an adapter plug to convert the power supply.

The Basics when Looking for an Dell pa-10 adapter

Try and Find your specifications for your Dell pa-10 adapter. On the old adapter, Device wishing to supply or specification page in an owners manual. The specs are usually given as volts and milliAmps (mA). Always try and find a exact match of specs. This is the safest way to go. Where an exact match is not available a couple general rules of thumb to find a workable adapter.

Choose the closest voltage available . Safer to go lower the higher. Some devices can handle higher without damage but many will not take it. If you choose lower generally the worse that would happen is it would not supply adequate voltage and equipment would not normally be damaged.

Choose milliAmps equal or higher than required

2) Regulated (Switching) or Unregulated (non-switching) Output

Most AC adapters are unregulated, Voltage output of the power supply floats with the load placed on them. Some electronic equipment such as digital cameras or security cameras are very sensitive to the input voltage and so require a Regulated/Switching adapter.  A regulated AC adapter guarantees that the output voltage will always be constant.

Do Not use an unregulated supply in place of a regulated one!

Ok to use a regulated (however generally pricer) in place of an unregulated.

3) Output plug size/ Output Polarity

These are measured in mm. I will try and give these measurements as accurately as I can. If the plug is not correct for your application. Radio shack or another supplier may have an adapter or the existing plug can be spliced to the replacement adapter if you be sure to check polarity before attaching to the equipment.

Output Polarity

Adapters with an AC out put this is not an issue however ANY and ALL DC adapters it must be observed or equipment damage most likely will occur.

With the popularity of the cellphone has come another industry as well. Sales of cell phone batteries, cases, earphones are all benefiting. Cell phone batteries are the life of the phone. Without them the phone will not work. But they need to be charged in order to work. There are several types of chargers. Choosing the right one or having an additional charger can be a lifesaver. A handcrank charger can get the phone working if there is no electricity at all or if you away from an electric power source. If you are traveling in a foreign country, there might not be the same electric current and an alternative charging method will be necessary to take pictures, and videos in addition to regular cell phone use. This article covers some of the types of cell phone chargers available.
These are the standard chargers. Most cell phones and laptops come with this type of charger. They are very hardy and charge fairly quickly. The more portable the device the more chances the charger will get lost. As a result, chargers are one of the most popular of all consumer products because they are lost often especially cell phone chargers. This type of charger works simply by connecting the charger to a electric source and the device ie. cell phone or laptop to the charger. Some chargers have several ports for charging several phones and/or laptops.
A car charger is a  phone charger that charges from the battery of a car. These use a specialized plug that hooks into the cigarette lighter socket of the car. This can allow a phone to be charged while on the move, which makes it a great option for travelers. Traveling salesman can benefit from this especially those who do presentations on the road. Charging your battery can ensure it will be available for Powerpoint presentations, video conferencing or other types of work on your phone that require a lot of energy. You can also use it if you are planning to record favorite scenes from a sporting event as well. In some cases, a back up battery is a great idea all together. A car charger is great  backup if a wall charger fails or is lost.
Wireless chargers are very interesting. They use inductive charging to charge everything from cars to phones. There is a charging station. The station will create the electromagnetic field the device will convert back to electric current and charge the battery. This is a very clean way to charge with less wear and tear on the parts of the phone. One draw back is it takes longer to charge than the direct plugin the wall type charger.
A rapid or fast charger can give a dying battery much needed power in half the time of a regular charger, but may come with a risk. These chargers can charge much faster than a standard wall or travel charger.  This is only if the phone will allow the fast charger to operate at full speed. Not all phones have the capacity to receive the amount of charge that fast chargers are capable of putting out. It is important to check your phone charger for the amps output. Also late model phone chargers have fairly fast charging times and a fast charger might not be necessary. Fast chargers get very hot. Though many incorporate a small fan for cooling purposes, cheaply made fast phone chargers can damage the battery if left plugged in for too long. Using fast chargers can reduce the overall battery life and make the battery unable to charge to full power.

Some unusual phone chargers are available on the market for those who enjoy gadgetry or are looking to reduce waste. Solar phone chargers use small solar panels to capture the energy in sunlight and use it to restore the battery. These can be a very good choice for people on camping or hiking trips who will be away from standard power sources. A similar alternative is a hand-cranked charger, which uses manual power to provide a charge. These phone chargers may take serious arm work to provide a decent amount of charge, but have the benefit of not needing sunlight to charge in remote locations.

Hand cranked chargers are a great to have for several situations. For camping or outdoor trips, there is no telling if weather will be suitable for charging a battery with a solar charger. And you don't know when your battery will need to be charged up again. It could be in the night. Another great reason for a hand cranked charger is you might be in the middle of a storm and not have any electricity to power or charge any device. In this case, a hand held is one of the best options for spare charger power. It might be laborious to crank power to your phone but you will be able to use it.

There are several types of chargers to choose from. All the chargers will be more or less beneficial depending on the user. A tv cameraman who is on the road often will benefit from a car type charger or a traveling salesman. A student may need the standard plugin charger. Those whose work involve being outdoors like a guide might benefit from solar type chargers. Chargers that use a hand crank are good backup for emergencies especially if no land line is available. The choice of charger is as individual as the lifestyle of the user.

Blinking green light on the laptop AC adapter

If your laptop ac power adapter also known as a power supply has a blinking or flashing green light and the laptop / notebook system does not power up at all while the ac adapter is plugged into the laptop, then you have a short on the motherboard. Also if you have a light on the power jack/ input /port that usually blue when you plug the cord in and it is not blue anymore (i.e.hp Pavilion DV6000 AC Adapter or hp Pavilion DV9000 AC Adapter series?then it is also a short on the board.
You plug in your ac adapter into the wall ac power outlet; the light on the ac adapter is solid green at that time. As soon as you connect the ac adapter’s plug into the laptop the light on the ac adapter dims and does not show green at all until the next time you unplug the ac adapter from the laptop and from the wall or the ac power adapter could simply be blinking green. At the same time system does not power up from the ac adapter.
This means that once the short is being encountered the AC adapter, power brick, power supply shuts itself down, once it shuts itself down the green light goes out. If the ac adapter is more advance it tries to restart itself thus the blinking light. Every time ac adapter(Dell Inspiron 4000 ac adapter) restarts the shortage happens and thus the light comes up and dims out.

Unregulated DC Power Adapters

Regulated or un-regulated: what does it mean?
A voltage regulator is a device (usually an electronic circuit) that controls or maintains the constant voltage output of a power supply. Some (more expensive) DC voltage output power adapters have voltage regulators built in, while most do not.

Unregulated DC output power adapters are still the most common type of power adapter in use today. Unregulated, or "non-regulated" simply means the power adapter is not subject to the control or authority of a voltage regulator. With unregulated power adapters, or any other unregulated DC power supply, the DC output voltage is dependent upon an internal voltage reduction transformer, and related to the amount of current used by the electrical load. (The load is the device receiving power from the adapter).

Example: A given unregulated power adapter has an output rating of 9 volts DC at 500ma (500 milliamps = 0.5 Amps).
This rating means that the unregulated voltage output of the power adapter will be 9 volts DC when it is under the full rated load of 500ma. Many people are surprised when they plug an unregulated power adapter into a wall outlet and measure the DC output voltage of the power adapter with a volt meter. While the adapter is providing no power to a load device, the measured output voltage is several volts higher than the rated voltage of the power adapter. Often, people jump to the conclusion that something is wrong with the power adapter, while the simple explanation is that the power adapter has no voltage regulator, and this is normal. But if the same unregulated power adapter is connected to a load which draws 500ma of current, the measured output voltage of the power adapter would drop to the rated 9 volt DC output level as it should.

The second important concept to understand about any power adapter, whether regulated or unregulated, is that the rated output current of the adapter should not be exceeded by the maximum current requirement of the load.

Example:  If a power adapter has an output current rating of 500ma, it should never be connected to a load that will draw more than 500ma of current from the adapter. Drawing more than the rated current output from an unregulated power adapter will certainly cause the actual output voltage to drop below the rated value, and overloading any power adapter in this way will lead to overheating and premature failure of the adapter. Overloading a power adapter may cause a fire hazard and depending on the power sensitivities of the load, may cause damage to the load as well. Most power adapters made today, have built in overload protection (essentially an internal fuse to prevent the adapter from going up in a puff of smoke), but overloading the adapter may still cause it permanent damage. Appropriate external fuse protection can be added if the extra precaution is warranted.

A third concept about unregulated power adapters which for most applications is less important, but still helpful for people to understand, is that unregulated DC output power adapters do not produce a pure and "clean" DC voltage. But if the power adapter selected is closely matched to the power requirements of the load, the purity of the DC voltage produced is more than adequate for many jobs (with few exceptions).

Proper Laptop Adapter Care

Laptop adapter is very important especially if the computer’s battery is getting low or drained. So, proper use and maintenance should be observed to keep the adapter in good condition. Of course, no one wants to have a non-functional laptop adapter/charger because it can lead to unproductive work if the computer doesn’t have power.

Here are some practical tips on using as well as taking care of your laptop power adapter:

1. If the power adapter is not working. Check first if the outlet is live before doing serious troubleshooting on the device.  In this way, it will save your time and effort as well as avoid unnecessary repair.
2. Use only the model-specific adapter for the laptop. Don’t use it in other gadgets even if the output voltage requirement is the same because the current might be different.
3. Always put first the DC output plug into the laptop’s power jock before putting the input plug on the power outlet. This is the correct method.
4. Don’t leave it connected into the computer for continuously long periods of time. If the battery is full, gently remove the cord in the laptop’s jock port.
5. Place the laptop adapter in an area where it will not fall. Keep it in a safe location where it can be hard to reach for children. Also, avoid dropping it to avoid damage.
6. Don’t shake or knock the adapter. Improper handling may break the internal parts and circuit boards.
7. Don’t place the notebook adapter in a cool place or near the air conditioner to avoid the device from getting moistened.
8. Avoid the metal tip of the adapter from getting in contact with other metal objects because it can cause short-circuiting.  Your computer might get damage when a short-circuited charger is used.
