Abstract:

An improved circuit for energizing and quickly deenergizing the DC operating winding of an electromagnetic relay or contactor from sources of AC supply. It employs a full wave rectifier bridge, a transistor for initiating and maintaining the energization of the relay or contactor control winding when AC is supplied to the bridge, and a zener diode connected in parallel with the main conducting path of the transistor to facilitate quick deenergization of the control winding when the AC supply to the bridge is interrupted.
