  • NI ELVIS II

Issue Details

We have several NI ELVIS II boards, but the output of the +15V power supply is not accurate and pure 15V. Some boards output 15.5V and others 15.6V. Why we are not getting exactly +15V?
 

Solution

As per the specification sheet of NI ELVIS, the +15V power supply has +/-5% voltage accuracy which means the voltage range can be between (-15*1.05) and (+15 *1.05) which is from -15.75 to +15.75.
