Cliff Test – Constant Current Variable Load

 

Check out the Cliff Test, it is a Constant Current Variable Load by TimNJ. It is based on the popular inexpensive load tester circuit that Dave Jones built a while ago. 

“Here’s some information about it:

-External AC/DC power suppply
-Fan cooled (no temperature control at the moment)
-Load switch (with LED indicator)
-10-turn pot
-Internal trimmer to set max current (currently set at 1A, but can most likely do 2-3A)
-Yellow and black banana jacks for current measurement (1A/1V)
-10x 10ohm Vishay CPF3 (3W) resistors”
