2k Variac (Variable Transformer):

A variable transformer is designed to provide variable output voltage that can be adjusted from 0 to 117 percent of the unit’s input voltage. It consists of a copper winding on a toroidal core of laminated, grain-oriented, silicon steel. A carbon brush, connected to an output terminal, is rotated over the length of a precision-ground, precious metal-plated, commutator track to tap off voltage at any turn from zero volts to the maximum output voltage of the winding. The cased plug-in model variable transformer features a ventilated steel case, input line cord and plug, fused NEMA rated output receptacle, and an illuminated on/off switch. It is connected for output voltage increase with a clockwise rotation, and the dials are graduated from 0-100 percent of the voltage setting.
