Many operational mode choices are possible, and each can be configured by the user while remote from the power manager. The power manager can be commanded to upload a user configuration list, and it can be commanded to accept a downloaded user configuration list.

Power distribution unit and methods of making and use including modular construction and assemblies

Power distribution apparatus with input and output power sensing and method of use

Power distribution apparatus with input and output power sensing and a method of use. A power distribution unit includes a sensor that senses power parameters of power outputs and a power input, a processor, and a communication circuit. A power management system includes a power manager, a user interface, and a plurality of power distribution units that may be located in one or more equipment cabinets and data centers. The system may compute apparent power, RMS power, power factor, energy usage over time, power usage history, or environmental history for any or all of the power distribution units. The system may identify an under-utilized server connected to one of the power distribution units and initiate a shut-down of that server.

Wireless communications capable power distribution unit and techniques for communicating therewith

A method for providing wireless communication between a PDU and other wireless devices is provided. A wireless controller receives an indication that a discoverability button has been pressed. The wireless controller accesses PDU discoverability information from a computer memory. The wireless controller broadcasts the PDU discoverability information for a pre-determined period of time.

Power distribution, management, and monitoring systems and methods

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 'infeed' table for data descriptive of input electrical power, and an 'outlet' table for data descriptive of electrical power flowing through the outlets.

Method and apparatus for multiple input power distribution to adjacent outputs

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.

Transfer switch with arc suppression

An automatic transfer switch for a power system receiving multiple alternating current sources and delivering multiple alternating current output is described. A transfer switch control circuit can sense a power loss in one or both AC sources. Each power supply can deliver current to drive a load but, if one of the power supplies fails, the other can supply power to drive both loads.

Vertical-mount electrical power distribution plugstrip

A vertical-mount electrical power distribution plugstrip comprises a long, thin plugstrip body with several power outlet plugs distributed along the length of one face. A power input cord is provided at one end, and this supplies operating power to each of the power outlet plugs through individual relay control.
