A carbon \n\nbrush, connected to an output terminal, is rotated over the length of a \n\nprecision-ground, precious metal-plated, commutator track to tap off \n\nvoltage at any turn from zero volts to the maximum output voltage of the\n\n winding.  Unlike a standard fixed ratio transformer, a Staco variable \n\ntransformer \n\nis designed to provide variable output voltage that can be adjusted from\n\n 0 to 117% of the unit's input voltage.
