Abstract
A remotely controlled electronic general switch in DC power electrical supply system(s), ensuring switching and control of current and supply voltage, has an electronic module. The module has a controller or processor connected (i) to the switching and measurement circuit, the controller and measurement circuit optionally being linked bidirectionally, the controller being configured such that, when it receives a voltage and current measurement of the measurement circuit, it is respectively able to verify whether the input voltage lies in a predetermined interval and to instruct current interruption by the switching circuit for a certain duration, as a function of the measured current value, and (ii) to the communication interface, the communication interface connected to the communication bus and controller optionally being linked bidirectionally, such that the controller can be programmed remotely. An addressing bus, connected to the controller, enables selection, from several systems, a particular supply system linked to the general switch.
