Abstract

The present disclosure relates to a modular DC power unit having a form factor enabling mounting in at least one of a plurality of component locations of an equipment rack. The modular DC power unit provides DC power to a DC bus of the equipment rack. The modular DC power unit may have a chassis defining a plurality of slots into which a plurality of DC power supplies may be inserted. An AC input module may be used for receiving AC power from an external AC power source. A plurality of independent, modular DC power supplies, each having a form factor enabling insertion and mounting in one of the slots of the chassis, may be mounted in the chassis. A controller may be in communication with the DC power supplies and housed within the chassis. A DC bus housed within the chassis communicates with the DC power supplies and supplies DC output power from the DC power supplies to the separate DC bus housed within the equipment rack.
