Techopedia Explains Power Distribution Unit

A power distribution unit is an electrical device that has multiple sources of integrated power outputs. Each power output socket can be connected with a computing or networking device directly. There are two types of PDUs: floor mounted and rack mounted.

A PDU has the ability to manage and distribute large amounts of electricity and usually is directly installed in the rack. PDUs generally have the ability to be connected and accessed over the network or remotely, and provide data and statistics on the power usage effectiveness (PUE).
