Hello
Can anyone point me in the direction of a circuit diagram for an electronic load? I have downloaded one from Elecktor but it is a bit more involved than I would like. (But if it's all I can find then it will suffice).
I want to load computer ATX power supply 12V lines mainly up to 20A. (If it works on the 3V3 and 5V0 lines then thats a bonus). I am currently doing this with a monster heatsink and aluminium clad power resistors but I would like to have more control. Something using MOSFETS or high power darlingtons would be ideal controlled by a potentiometer.
All input appreciated.
Regards
Paul
