The PDU includes power inputs. The power inputs are configured to receive one or more of: alternating current (AC) power, high voltage direct current (DC) power, single-phase fault managed power, or multi-phase fault managed power. The PDU further includes at least one fault managed power module configured to be contained in the housing, the at least one fault managed power module including a power transmitter configured to generate single-phase or multi-phase fault managed power from the AC power and/or high voltage DC power.

Fault managed power in a power distribution unit

Techniques are provided to synchronize a remote power switch at a power receiver end of a power cable with a first power switch operation at a power source end of the cable, without any physical or data communication means for synchronization. This process may involve synchronization of a MOSFET-type switch with voltage pulsing at the power source cable end to a MOSFET-type isolation switch at the power receiver cable end to provide (voltage or load) power during the On-time and safety testing for a shock hazard during the Off-time. This method synchronizes switching pulses by sensing and synchronizing on the cable switching voltage transients from the source side. This method also involves blanking the additional switching voltage transients on the cable generated after the synchronized switching begins to maintain proper synchronization. These techniques may be used for a single-pair pulse power cable or with multi-pair multi-phase pulse power cables.
