Will the G540 work using a low voltage source (5v wall wart or 7805 circuit) for less contact arc? I can lower the amps with a low amp fuse, but the 48v of my supply seems high. I "feel" safer with low volts in the control circuit.
If the G540 can do this with a low voltage, I know I'd need to connect the negative to the supply/selinoid negative star hook up point. Or am I just being too cautious?
