The basic Spectron Continuously Variable Voltage Auto Transformer is meant for operation of a nominal voltage of 240V AC and can give output voltage anywhere between 0 tp 240V, or upto V by a simple transformer action. Three such Spectron Continuously Variable Voltage Auto Transformer when connected electrically in star, and mechanically in tandem, become suitable for operation off 415V 3 Phase AC supply and to give output from 0 to 415 V or up to 470V.
