Each relay is associated with a specific outlet to control power to the outlet and attached electric device.

A method of limiting a total power delivered by a power distribution unit having a plurality of output connectors is disclosed. A configurable power threshold is assigned for each of the output connectors so that a sum of the configurable power thresholds of the output connectors does not exceed a maximum rated power for the power distribution unit. A power level of a given output connector is sensed. A delivery of power by the given output connector is stopped when the power level of the given output connector exceeds the configurable power threshold for the given output connector. Power delivery may be resumed in response to receiving a user command to rearm the given output connector. A power distribution unit adapted to limit its total power delivery is also disclosed.

Power distribution units, power distribution systems, and related methods for controlling relay switches of electrical cords are disclosed herein. According to an aspect, a PDU includes multiple electrical plug receptacles for operatively connecting to one or more electrical cords for providing power to the electrical cord(s) to transmit power to connected electronic devices. The electrical cord(s) each include a switching relay configured to control transmission of power via the respective electrical cord. The switching relay is configured to receive a control signal for controlling the transmission of power. The PDU includes a connector to a power source configured to supply power to the electrical plug receptacles. Further, the PDU includes a communications module configured to individually route control signals to the switching relays for individually controlling transmission of power via the respective electrical cord(s).

The invention relates to a master distributor strip for distributing electrical energy for equipment and/or server cabinets, comprising a plurality of connection means that are provided on a face of the master distributor strip, and to which electrical loads can be connected for the purpose of energy supply. Furthermore, sensors for determining data at least relating to the status of the master distributor strip and/or of the plurality of connection means are provided. The invention is characterized in that a communications module is provided, which module is configured to retrieve and/or receive the data of the sensors, and to communicate with at least one sensor and/or actuator that is remote from the master distributor strip, by means of a communications network. The master distributor strip furthermore comprises an information and management module which is configured to provide the data of the sensors, retrieved and received by the communications module, directly to a user, via a communications network interface.

A power distribution unit (“PDU”) comprises a housing, a power module mechanically connected to the housing, at least one outlet module separately and mechanically connected to the housing, and a communications module mechanically connected to the housing. The PDU includes busbars that are electrically connected to the modules.

A system and method is disclosed for detecting a specific voltage phase, from a multiphase voltage source, and a specific outlet of an intelligent power strip, that is associated with a residual current flow. The method accomplishes this by using a system that employs a statistical time series analysis using a Pearson's correlation coefficient calculation to measure the linear dependence between the discretely sampled residual current waveform and each phase and outlet's discretely sampled current waveforms, in turn. A residual current as low as 1 mA can be accurately measured and its associated voltage phase source, as well as which outlet of an intelligent power strip it flows out of, can be reliably determined.
