Abstract

Current economiser device for the power supply of resistive electric loads, especially the resistance 3 for the heating of the rear window 5 of a vehicle, via a series of insertion/disinsertion cycles. The resistive load 3 is initially energised for a predetermined period of time To of approximately 3-4 minutes, after which the power supply is interrupted if the number of revolutions of the engine of the vehicle drops below a predetermined value. The device 1 comprises a timing circuit 7 to control the power supply of the load for the predetermined time To, and a threshold comparison circuit 10 able to compare a signal proportional to the number of revolutions of the engine with a reference limit value to enable the power supply of the load 3 only when the signal proportional to the number of revolutions of the engine exceeds the reference limit value. <IMAGE>
