System and method for programmably operating DC loads

A system for programmably operating a DC load, the system comprising:

• a DC outlet operatively connected to the load;
• a power line communication (PLC) client at the outlet for measuring actual and desired DC voltage at the load;
• and
• a DC power server located remotely from the outlet and being operatively connected between a DC power source and the outlet, the power server having a PLC master in bidirectional feedback communication with the PLC client to determine the actual and desired DC voltage at the load, the power server further having an adjustable DC voltage module controlled by the PLC master to supply an adjustable DC voltage, the power server being operative for adjusting 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.
