Abstract

See full text

A computer-implemented apparatus and related method control a dynamic phase rotation unit of a power distribution unit (PDU). The method comprises using a processor of a system controller for identifying a PDU group of two or more redundant PDUs, receiving input parameters from an input port of each of the PDUs in the PDU group, and comparing the input parameters from of the PDU group. The method further comprises conditioned upon a determination of the following both being true: 1) the input parameters are within a predefined threshold of similarity; and 2) no uninterruptable power supply (UPS) is present, then, responsive to the determination sending, via a network, a phase rotation command to a phase rotation controller to change the phase rotation switches on at least one of the PDUs in the PDU group. Otherwise, responsive to the determination, not sending the phase rotation command.
