Abstract (en)
Control system and method for an electromechanical contactor of a power circuit, the electromechanical contactor comprising:• a contact (1), movable between two positions: an open position and a closed position in which the contact (1) produces the connection,• a coil (2), in mechanical connection with the contact (1) and configured to drive the contact (1) between the open and the closed positions.The control system comprising a regulated power supply (3) connectable to the coil (2) and a controller (4) for varying the relationship k between the output voltage V<sub>OUT</sub> and the feedback voltage V<sub>FBK</sub> from at least a first relationship k<sub>1</sub> to a second relationship k<sub>2</sub>, being k<sub>2></sub>k<sub>1</sub>, such that, the regulated power supply (3) varies the provided output voltage V<sub>OUT</sub> from a first output voltage V<sub>OUT1</sub> to a second lower output voltage V<sub>OUT2</sub> for reducing power consumption of the coil (2).
