Black or Green Terminal on a Power Supply

Posted on: December 16th, 2020 by Doug Lovell

Our power supplies are isolated power supplies. So when you connect to the black negative terminal you have connected your DUT to an isolated channel.  Where as if you connect to the green terminal you are connecting your DUT to ground which will no longer have the power supply act as an isolated supply.
