A magnet generator controller has a variable voltage array fabricated as a formation of receptacles mounted on a printed circuit board and interconnected via traces to pairs of taps off a transformer winding, and a plug-in connector that inserts in a selected receptacle to electrically couple one of various pairs of the taps to a field winding output in a mode of operation of the controller. This sets the voltage of the field winding output in the mode. The magnet generator controller also has a function select switch that allows selection of a run function in which the magnet generator controller sequences through plural modes (e.g., extra lift, lift, and drop modes) with associated field winding output settings in response to an operator control switch and timers. For use during set-up or fine-tuning, the function select switch also allows selection of exclusive mode functions in which the magnet generator controller operates indefinitely in an exclusive one of the modes.
