Protection device for protecting a voltage source and a load supplied thereby

摘要

A device for protecting a voltage source and a load supplied with power by the voltage source, comprises a switching element interposed between the voltage source and the load and is associated with a current limiting circuit including a measuring unit for measuring the current provided by the source and a control unit for controlling the switching element so as to prevent the current from exceeding a predetermined current threshold, and a voltage limiting circuit adapted to control the switching element so as to prevent the voltage supplied to the load from exceeding a predetermined voltage threshold.
