So far I'm impressed with this:

Yeah, that's probably good for 7A. Teensy!


AFAICT it performs as advertised. My variac + arc welder transformer
power supply goes to 57VDC or 70ADC but not both at once, and not over
30A for very long. I'm fairly sure I used it to test the DPS5015 at
15A to at least 35V but I can't find the data. It's a difficult
measurement because my power resistors have to be reconfigured several
times as the voltage rises and they get very hot, 500-600F.

At least it's not C. Sounds like a pretty nifty supply. Was that a
little fan on the backside of the power transistor mount plate? Still,
they don't look up to 7.5A each, so I'm surprised. Cute little guy.
