Patent ID: 8390441

Claim:
A power device comprising: a power converter configured to provide power to a plurality of load devices over a plurality of conductors when the power converter is electrically coupled to the load devices with the conductors, wherein the conductors propagate the power from the power converter to the load devices as direct current power signals; a power communicator configured to receive data digitally transmitted by a plurality of load communicators over the conductors that propagate the direct current power signals to the load devices, wherein each of the load communicators is paired with a corresponding one of the load devices; and a processor configured to determine a target power level for each of the load devices based on the data digitally transmitted by the load communicators over the conductors that propagate the direct current power signals to the load devices, and wherein the processor is further configured to cause the power converter to adjust the power to the load devices in accordance with the target power level for each of the load devices.
