Hi,
I am building an ac/dc power supply for testing some controls that utilizes a variac. The AC output will be 0-135V from the variac at 0-20 amps. Is there any easy way to regulate the current output to a selectable amount? By that, I mean I would like to adjust the ac current limit via a pot knob and a current display. The power supply would then have current limit at that set point. I have spent several hours surfing the net and have not come up with anything. Any help would be appreciated.
