A power distribution unit (PDU), including: a housing; one or more outlets; a power input connector; a controller; multiple power input conductors coupled to the power input connector; a pair of conductors coupled to and extending between the power input connector and the controller; and a detachable power cord, including: a power cord connector mateable with the power input connector; multiple power cord conductors coupled to the power cord connector and in electrical communication with corresponding power input conductors; and a memory coupled to the power cord connector and in electrical communication with the pair of conductors, wherein the memory includes information pertaining to the power cord.

Systems and methods for providing input power to a power distribution unit

Disclosed are power distribution systems and methods in which a power distribution unit (PDU) includes a residual current monitor (RCM) to detect the presence of downstream leakage current in the PDU. The RCM can include a current sensor with a core that has power conductors passing through the core and drive windings about the core. Drive circuitry of the RCM produce alternating drive signals through the drive windings to drive the core into and out of positive and negative saturation. Sensing circuitry of the RCM produce a response signal that is filtered by a high-order current signal filter to isolate characteristics of the downstream leakage current.
