SYSTEM AND METHOD FOR PROTECTION IN POWER INSTALLATIONS

An apparatus and method for protection in power installations are disclosed. The apparatus includes a power converter (505,605) configured to convert input power to direct-current output power on a power converter output terminal, the power converter comprising a controller (306) and a receiver (507, 607). The receiver provides an enable signal to the controller in response to a presence of a varying signal superimposed on the power converter output terminal The controller shuts down the conversion of the input power to the direct-current output power if the power converter does not receive the enabling signal from the receiver.
