Junk box constant current dummy load

Another constant current dummy load. This one is capable of up to 10amps at 40volts.

Since I’m planning to build two bench power supplies, I needed to build a current load to test them. So, I’m going to show you my version of the dummy load. Please note that this project was built ONLY using existing parts in my personal stock.

Thanks MickM. Via the forum.

  1. Hi,
    Just wondering, how can I use the dummy load you created to test a negative power supply?
    Thanks!
