Frequently Asked Questions

Can I use an external battery or power supply with your systems?

NextComputing - Frequently Asked Questions
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.

Is it OK to use the power module and an external power supply at the same time?

Magellan Professional GPS
Yes, the Z-Max will automatically detect the power level of both batteries and seamlessly switch between them if necessary. The Z-Max will use the battery with the highest voltage.

Can I power from external supply?

Squirrel FAQs
Yes, 10-18V DC only. Includes 12V DC battery.What happens if the external supply fails? If the external power fails, batteries must be fitted to prevent loss of data. In the case of a power failure, the logger will switch to the battery supply and continue with no interruption.

How do we choose a power supply to charge a battery?

Mean Well AC DC and DC DC Switching Power Supply
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.

Is it OK to change or remove the power module if an external power supply is attached?

Magellan Professional GPS
Yes, the Z-Max will automatically switch to a suitable external power source without any impact on functionality. The Z-Max will only report capacity information from a battery it can communicate with. The power module is capable of this; power sources input through the external power port are not.

What Power Supply Should I use with a GL4000?

ALLEN & HEATH :: WORLD CLASS MIXERS
The correct PSU is the RPS11. This can be used with an RPSD2 for connection of a backup RPS11 with autoswitching.

What power supply should I use in a car?

MP3 Jukebox Player Frequency Asked Questions
The player module itself will operate on a regulated 5VDC @ 75 mA. So its actually the hard drive that is the significant power-hungry device. I would recommend using a 2.5" notebook/laptop hard drive for cars, as they tend to be more mechanically sturdy and also run off a 5VDC regulated supply @ ~1000mA. A single 12V-5V DC-DC converter can then be used to run the whole module. The cheapest way is to get a LM7805 3-pin 5V regulator and boost the current output (with a heatsink attached).

Can I use the internal and an external battery in parallel ?

service_faqs_rtus.html
Unfortunately not. When connecting an external battery the internal one needs to be disconnected. See also previous FAQ. NOTE: The electronics of the RTU's integrated battery charger can only provide a maximum charging current of up to 0.9Amps. Since batteries should be charged with at least 1/10 of their capacity, the maximum capacity of an external battery should thus not exceed 9Ah.

What is the power battery holder HLD-3?

Evolt E-300 Digital SLR Camera > Frequently Asked Question...
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.

Is it possible to connect an external power supply in order to extend the working time?

Magellan Professional GPS
Absolutely. An external power supply kit will be available as and additional accessory. It is based on a battery similar to the one internal to the ProMark3 unit installed in a pouch, connected to the receiver with a waterproof cable/connector. For easy portability, the pouch can be attached to the ProMark3 field bracket. Such a system extends the autonomy by eight hours in typical operation conditions.

Do I need any external device like a power supply in addition to the LCIC?

I.M.S. - Industrial Measurement Systems Ltd. Technical Suppo...
No- The LCIC board equipped with switching power supply to provide the excitation to the load cells. Just attached the Load cell cable to the board and you are ready.

Do I need a special power supply?

Flow meter, mass flow controller, mass flow meter, flowmeter...
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.

What kind of Power Supply is needed? Can I use an ATX Power SUpply?

SIMKITS - Flight Simulator Parts - Frequently Asked Question...
The Central Control Unit is powered by a standard 200 Watt PC AT Power Supply through a diskdrive connector. These power supplies are available around the corner. The Central Control Unit on its turn powers the servos through the flatcable. The newer ATX Power Supplies do not switch on automatically when used stand-alone. These Power Supplies are switched on by the PC Mother board normally.

How can I get a negative voltage out of a single battery for a bipolar power supply?

Common Questions Beginners Ask and their Answers
Check out the ICL7660, 7662, LT1026, voltage converters. They can double, produce negative voltages etc... from a single battery.

What external power supply requirements are necessary for my DSP-3 module?

Frequently Asked Questions
The DSP-3 requires a 15V DC supply with a current capacity rating of at least 300mA. The output termination is via a 2.5mm barrel type (coaxial) connector. Center pin is positive.

I have a separate power supply for my Roll-Up---do I really need to use it?

Technical Support - Digitizing & Measurement Products - ...
Yes. Although the Roll-Up does get some power from the computer, the external power supply is needed to ensure a constant power source. This is especially true if you are using the digitizer with a laptop computer.

I have a separate power supply for my Roll-Up III---do I really need to use it?

Technical Support - Digitizing & Measurement Products - ...
Yes. If the Roll-Up III connects via serial port, the external power supply is needed to ensure the digitizer has a constant power source. This is especially true if you are using the digitizer with a laptop computer. The power supply is not needed if the Roll-Up III connects via USB port.

Do you have a power supply I can use for fieldbus?

Fieldbus FAQs : Relcom Inc.
We do not manufacture devices to convert AC Mains power to 24VDC. All of our Fieldbus Power Conditioners require a nominal 24VDC power supply. MTL does manufacture a Class I Division 2 power supply. Please see their web site at www.mtl-fieldbus.com
