[′pau̇·ər ‚di·strə′byü·shən ‚yü·nət]

Equipment located in or near a computer room which breaks down electric power from a high-voltage source to appropriate levels for distribution to the central processing unit and peripheral devices. Abbreviated PDU.

power distribution unit

A device used in datacenters to distribute AC power to multiple servers and other equipment. Power distribution units (PDUs) range from simple 120v power strips to units that break out 120 volts from 240v and three-phase power. Advanced units are managed remotely via the SNMP management protocol or from a Web browser or other management console, causing outlets to be turned on and off at prescribed times and in a proper sequence for shutting down and powering up equipment. See power strip.


In the Rack
Most power distribution units (PDUs) are used to deliver power to rack-mounted equipment such as this basic 120v unit from APC. (Image courtesy of American Power Conversion Corporation.)
