POWER SUPPLY AND CONTROL CIRCUIT OF A SOLENOID AND PILOTING OR SWITCHING DEVICE PROVIDED WITH SAID CIRCUIT

The present invention relates to a power supply and control circuit (20) of a coil or of a solenoid that can receive in input alternating or direct current with variable voltage and possibly also frequency, said circuit comprising a multi-voltage rectifier circuit (25) that can be supplied with alternating or direct input current, a current control circuit (29) and a universal driver (26), which in turn comprises a direct current power driver (27), adapted to be connected to the coil or to the solenoid to be supplied, and a PWM controller (28) of the output circuit, wherein the rectifier circuit (25) supplies the power driver (27), wherein said power driver (27) drives the PWM controller (28) which supplies the coil or solenoid and wherein the universal driver (26) is connected to the current control circuit (29) and is driven in feedback thereby.
