Frequently asked questions
What do the CC, CV, CP and CR modes do?
CC draws a set current, CV holds a set voltage, CP draws a set power, and CR behaves as a set resistance. These modes let you test a power source under different load conditions.
How should I connect the load to a device under test?
Connect the input terminals to the device under test with correct polarity, using cables rated for the expected current. Keep the total load within 120 V, 30 A and 150 W.
