Check out the ICL7660, 7662, LT1026, voltage converters. They can double, produce negative voltages etc... from a single battery.

Yes, NextComputing recommends APC brand UPS/DC power pack bricks. These units usually provide 15–30 minutes of power, depending on your system's configuration. See similar questions...

MEAN WELL has ESC, SC, PA, PB series for battery charger purpose (120~360W). If these series does not meet customers’ demands and they like to choose a power supply as a charger, we advice to pick up one which over load protection (OLP) mode is constant current limiting. The models in this mode provide constant current even when the protection circuit is triggered. The second choice is fold-back current limiting or constant wattage model. See similar questions...

a. Normally this not a problem as long as the motor operates within the speed and current limits set by the manufacturer. Since motor speed is proportional to the voltage across the motor leads, select a power supply voltage that could not cause a mechanical over-speed in the event of an amplifier malfunction or a runaway condition. See similar questions...

The torque produced by the motor is affected by changes in power supply voltage. The torque the motor produces is proportional to roughly twice the power supply voltage. For example, if the voltage of a motor rated at 115 VAC fluctuates between 103.5 VAC (90%) and 126.5 VAC (110%), the torque produced will vary between 80% and 120%. When using motors under large power voltage fluctuations, remember that the torque produced will vary, so select a motor that provides a sufficient margin. See similar questions...

For the BayStack 600 series and the Netwave AirSurfer Plus APs the power supply output specification is: 6V DC, 1A, center pin +ive. For the Xircom CNW and Netwave AirSurfer Access Points the power supply output specification is: 12V DC, 1000mA, center pin +ive. See similar questions...

The supply voltage may be higher or lower than the voltage required by the load. However, the frequency of the two may not differ. If your load ratings are not expressed in KVA, use the load voltage and amperage to determine the KVA. Once you have a KVA rating, then select a transformer from the charts in the appropriate section of this catalog by matching the primary and secondary voltages determined above. See similar questions...

Yes. However, the maximum power output per channel with all channels driven simultaneously will be decreased. The power output with only one channel driven will not be affected. See similar questions...

The HLD-3 power battery holder can hold two Li-ion rechargeable batteries (BLM-1). This enables you to use the camera twice as long as a single use battery. Additionally the holder provides remote cable connector and shutter button, which is convenient to take pictures while holding the camera vertically. See similar questions...

No, the 810 and 820 series meters operate in using a "single ended supply" meaning you only need between 9 and 25 VDC to operate them. We sell very reasonably priced power supplies that accomplish this in a very economical manner. See similar questions...

Please keep in mind that everyone's situation is different. Never let a "bipolar label" overshadow who you are as an individual. However, while individual differences shouldn't be underestimated, it's also amazing the amount of common experiences people with bipolar illness share. It's hoped that these questions and answers will get at some of the basic information you may need as you begin to explore what bipolar illness means in your life. See similar questions...

The BCM-1 Battery Charger (Item #260206) for the EVOLT E-510 is rated at 100-240 V AC and automatically adjusts itself for the local electrical current. However, you may have to get a set of plug adapters for the different wall outlets used in foreign countries. Plug adapter kits are available at electronics and luggage stores. The EVOLT E-510 accepts CompactFlash cards up to 8 GB capacity and supports Write Acceleration CompactFlash cards. See similar questions...

The no-load voltage is around 12.9 V, so anything less than that while the engine is running means that the battery is discharging. See similar questions...

Most of our food is bought fresh in Bintan and taken out to Pangkil on the morning of your trip. To plan menus and organise the land and launch transport we ideally need to know the size of your group and your ferry time(s) a week before your trip. Small changes to the number of guests closer to your date of departure are fine. In this case, if she is planning on being on the same ferry as the rest of you, you can let us know on the Friday.

my logic says ,it can be used but i don't know its consequences or,side effects,if any,please help me. using a scott transformer, feeding two single phase loads, which are unbalanced, how dramatically could this affect the overall power system? Are power electronics and svc the only solutions to mitigate the problem? Which solution is most appropriate> My name is Jose Garcia, EE. My Company: AGC Electric & Recycling Contractors Inc., Miami, FL. See similar questions...

A battery charger is a type of DC Power supply (PSU) which is specifically designed for charging batteries. While any DC Power supply can be used to charge batteries, there are serious potential pitfalls to using a generic power supply as a battery charger. For example, a DC Power supply may include regulation circuits, which may be damaged if a battery is connected to the output, before the AC Power supply is switched on. See similar questions...

Accordingly, voltage measured right after removal of the tab is normally lower than specified voltage of 1.4Volt. This has nothing to do with battery capacity and you do not have to worry at all. It will be fully activated as you use the battery. We would like to suggest that you insert the battery into your hearing aid at least 1 minute after removal of the tab to allow for proper activation time. See similar questions...

Will the spectrum work with an older Futaba Tx, namely the Field Force 3 (3UCP)? I note that the module for the 3PK is of the same size, but not sure if the internals are different. See similar questions...
