Power distribution systems and methods in which a power distribution unit (PDU) is provided with residual current monitoring at multiple outlets of an outlet module in a PDU. A residual current monitoring circuit of the PDU includes at least one current sensor associated with the outlets of the PDU to detect residual current for each of the outlets. The methods of residual current detection in a PDU having multiple power outlets includes detecting current leakage at each outlet as a difference between supplied current and return current for each outlet.

Per outlet residual current monitoring for power distribution units

Methods, systems, and apparatuses provide power from multiple input power sources to adjacent outputs efficiently and reliably. Aspects of the disclosure provide a power distribution unit (PDU) that includes a number of power outputs including first and second adjacent power outputs. The PDU includes a printed circuit board having a first conducting layer electrically interconnected to a first power input connection and the first power output, a second conducting layer that is at least partially above the first conducting layer and in facing relationship thereto. The second conducting layer is electrically insulated from the first conducting layer and electrically interconnected with a second power input connection and the second power output, the first and second power outputs thereby connected to different power inputs.

Method and apparatus for multiple input power distribution to adjacent outputs

A power distribution unit including a plurality of outlet cores arranged along an outlet panel of a housing and mounted to one or more circuit boards with an unobstructed space between adjacent pairs of the plurality of outlet cores. The outlet cores each extend a portion of the distance between the circuit boards and the outlet panel, and the outlet panel includes a plurality of apertures each corresponding to an associated one of the plurality of outlet cores. One or more overcurrent protection devices are mounted in a non-outlet panel aligned along the length of the housing.

Power distribution unit system incorporating smart cables and adapters

Disclosed are power distribution systems and methods in which a power distribution unit (PDU) is provided with an overcurrent protection device and per-outlet current sensing at each of the multiple electrical outlets of the PDU. The described embodiments enable the identification of the electronic device connected to a specific outlet or electronic device that may have caused the overcurrent protection device to trip. The methods of outlet identification in a PDU having multiple electrical outlets includes detecting whether either a peak current or a half-cycle root mean square (RMS) current at each outlet has exceeded a selected threshold prior to the occurrence of the trip event associated with the overcurrent protection device.

Circuit breaker forensics for power distribution units

Systems and apparatuses are provided in which outlets are coupled to a power distribution unit (PDU) or PDU module in various configurations. The outlets may be coupled to a recessed surface within a PDU housing. The outlets may be coupled to a printed circuit board that is at least partially disposed within the PDU housing. The outlets may extend away from the recessed surface or printed circuit board towards or beyond a front face of the PDU housing.

High outlet density power distribution unit

An adapter for interconnecting a power distribution unit (PDU) to electrical equipment. The adapter can include a first connector mateable with an outlet of the PDU and a second connector in electrical communication with the first connector. The second connector is mateable with a power input of the electrical equipment. PDU interface circuitry incorporating an optical interface can be housed in the first connector for communicating one or more electrical parameters of the electrical equipment to the PDU when the first connector is mated with the outlet of the PDU.

Managing electrical power usage in a power distribution system. Power usage data indicative of electrical current flow through electrical outlets in the system are collected and displayed for a user. The user may select an outlet and issue a command to control current flow through that outlet. Environmental data may also be collected and displayed. Outlets in different Cabinet Power Distribution Units (CDUs) in different locations may be clustered for reporting and control. A database structure provides a 'system' table for data descriptive of the system, a 'tower' table for data descriptive of outlets and other elements in the system, an &#x201c;infeed&#x201d; table for data descriptive of input electrical power, and an &#x201c;outlet&#x201d; table for data descriptive of electrical power flowing through the outlets.
