Abstract (en)

[origin: WO2007031356A1] The invention relates to relates to a control circuit for a relay. A coil (1) of the relay and a switch element (2) connected in series thereto are supplied by a first voltage source configured by a capacitor (4). Said capacitor (4) is connected to an AC voltage source via a charging connection configured from a first diode (5). The inventive control circuit also comprises an additional DC voltage source (U) which is connected in parallel to the first voltage source via a second diode (8). The current for maintaining the relay in the picked-up state is partially taken from the additional DC voltage source (U), thereby reducing the power taken from the first voltage source.
