ELECTRONIC CONTROL DEVICE FOR ELECTROMAGNETIC UNIT

摘要

The invention relates to an electronic control device for a switch unit ( 10 ), which comprises an electromagnetic actuator having a control coil ( 15 ) powered by an excitation current ( 26 ) for closing a power electrical circuit. The control device ( 20 ) comprises a unit ( 22 ) for storing at least one control profile giving a plurality of values of the excitation current varying as a function of time, and a drive unit ( 21 ) receiving at its input an external close command ( 25 ) and delivering at its output the said excitation current ( 26 ) following the said control profile during the closing of the power circuit.
