<p>A device (1) including a DC actuator (3), a rectifier element (D1, D2) and a switch (K) controlling the actuator power supply by connecting the actuator to the power grid via the rectifier element. The device is characterised in that the switch (K) enables the actuator to be electrically connected to the power grid, in that the switch (K) is a unipolar inverter with three positions (UP, DN, 0), and in that the rectifier consists of two diodes (D1, D2) connected to the inverter.</p> |
