The invention relates to a system for supplying a smart electronic relay which includes a micro-controller or another equivalent electronic circuit. According to the invention, the system comprises a filter rectifier (1) connected with a regulator (2), in series with which there is mounted an actuation element (3), a voltage reference (4) ensuring a voltage pre-stabilization at the input of a serial stabilizer (6), through which a microcontroller (7) is supplied, the stand-by current being sensed by a reaction element (5) which controls the regulator (2), the microcontroller (7) which actuates the actuation element (3) being connected with some analogic or digital transducers (10), with some operation buttons (11) or a communication interface (8) using an alternating current network. |
