Issue Details

My setup requires powering my CompactDAQ or CompactRIO system with a vehicle battery. Is this possible, and are there any downsides if the power supply fluctuates during operation?


You can use a vehicle battery to power your CompactDAQ or CompactRIO as long as the power supply voltage is within the specifications of your device. There are no adverse affects of a power supply that is fluctuating, as long as the fluctuations do not dip below or above the device's power supply specifications.

For more information, see the white paper Powering Your CompactDAQ or CompactRIO System.
