Abstract (en)
[origin: WO9626528A1] The new circuit has a control circuit (34), in which a switching element (2) and a measurement resistance (3) are connected in series to the contactor coil (1). A pick-up current regulating circuit (24) taps the voltage at the measurement resistance (3) and controls the switching element (2) after comparing said voltage to a reference voltage. By connecting in parallel another shunt resistance (41) to the measurement resistance (2), a current that is approximately twenty times higher in the pick-up phase than in the holding phase may be achieved with a single predetermined reference voltage. The parallel connection is cut off during the holding phase, so that only the measurement resistance (2) remains in activity.
