Dimmerstate/Variac/Auto Transformer
Variac These variable transformer deliver continuously variable A.C. voltage. The output is variable from 0-270 Volts from mains input of 240 volts. Contact between the winding and load is through a carbon brush which covers at least one turn of wire at all times. The areas of winding swept by the brush is plated with metal which eliminates oxidations and ensures a long working life with negligible maintenance.
