power distribution unit - Computer Definition
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.
