A variable auto transformer provides continuously adjustable AC voltage.

Description

A variable auto transformer provides continuously adjustable AC voltage. In it’s Auto transformer form it is an efficient, reliable method of controlling AC voltage from zero to line voltage by amplitude modulation of the AC waveform. Since the current, power, heat, light and motor speed are further functions of the voltage, the Dimmer Dot Variable Transformer finds its varied use, but is not designed to provide AC mains isolation.
