ABSTRACT:
A control system and method for acquiring and providing backup power to a plurality of distributive communication devices using a single DC APS system is described. The control system comprises a controller that senses the DC bus voltage of each distributive communication device connected to the controller, and controls the output of an auxiliary power source such as a DC generator, fuel cells, or any other suitable DC backup power source that is connected to the controller. The controller further comprises one or more switches which selectively connect each of the distributive communication devices to the APS in manner that prevents power surge currents. The controller further comprises a blocking diode to prevent ground loops between the co-located cabinets, and diodes to isolate each of the co-located cabinets power and ground.
