I'd like to have a way to "test" (place a load on) 12v DC power supplies by drawing 0-40 amps from them.
I have this 40A PWM module, and a power meter to put in front of it. I've used this against a home made bank of power resistors that could draw 10A and it worked well.
What would happen if I hooked this 40A pwm module up to a 100A car battery tester? Would I be able to dump the full 40A into it, or would that .12 ohm load destroy the PWM module?
I've been trying to find pictures of what the inside of the car battery tester looks like, I wonder if I might be able to easily rewire it into a 50A load. Of course I could buy two of them and connect them in series. But if the 40A pwm controller can't handle a load that tries to source more than 40A then even that wouldn't work.
Thanks
