Abstract: The present invention provides a self-contained converter plant for use in a modular power supply system. A modular power supply system includes a chassis having power unit bays each configured to receive a power unit module therein, a power distribution bus, a communications bus and a controller. In one embodiment, the self-contained converter plant comprises a housing having a power input connector configured to engage an electrical power interface on the power distribution bus and a converter communications connector configured to engage a communications interface on the communications bus. The converter plant further comprises a converter, and a power distribution device, all contained in the housing. The power distribution panel is electrically coupled to the converter.

Abstract: A grounding connector for use in a rack for receiving at least one module, the module rack having a power outlet associated therewith, the power outlet having a ground receptacle and power receptacles, a connector to allow a module insertable into the rack to be grounded via the power outlet and methods of operation and manufacture therefor. The connector includes: (1) a bracket coupled to a chassis of the module and (2) a ground pin coupled to the bracket and projecting from the chassis to engage and make an electrical connection within the ground receptacle, the connector remaining disengaged and electrically disconnected from the power receptacles thereby to prevent electrical power from being transmitted from within the power outlet.
