A system and method for programmably operating a DC load connected to a DC outlet. A power line communication (PLC) client at the outlet measures actual and desired DC voltage at the load. A remotely located DC power server is connected between a DC power source and the outlet. The power server has a PLC master in bidirectional feedback communication with the PLC client to determine the actual and desired DC voltage at the load. An adjustable DC voltage module at the power server is controlled by the PLC master to supply an adjustable DC voltage. The power server adjusts the DC voltage supplied by the voltage module to the load based on the bidirectional feedback communication between the PLC master and the PLC client.

A circuit comprises an output connector connectable to a load. A relay selectively connects the output connector to an AC power source. The relay is responsive to a disabling signal to disconnect the output connector from the AC power source. A sensor senses a level of power delivered to the load via the output connector. A detector emits a first fault signal when the sensed power level exceeds a fixed power limit. A latch maintains the first fault signal until it receives a rearm signal. A controller emits a second fault signal when the sensed power level exceeds a configurable power threshold, receives a user command to rearm the circuit, and in response to receiving the user command, emits the rearm signal and ceases the emission of the second fault signal. A logic combiner generates the disabling signal when it receives one of the first and second fault signals.
