|I have officially started on this massive controller for my
5K-Watt DC coil. This will not only control the fans and power to the rotor gap (variac to
change speed), but will also limit current and voltage to the pig. A hefty variac will
control the voltage and a large variable inductor will control the current. The pig does
not contain any current limiting properties, so an external current limiting mechanism is
essential. This monstrous gigantic cooper thing is already over two hundred pounds. I am
confident the time I finished with meters, fuses, and switches, this beast approaching
three hundred pounds. Adding pictures as I progress; tab on pics to enlarge.
