A power distribution unit (PDU) is a designed to distribute electric power to equipment in a data center or networking center. Power is typically distributed to racks of computers or networking devices via multiple outputs on the PDU. The PDU performs a number of controls related to the distributed power such as AC power monitoring, power metering, environment sensing and monitoring, and is equipped with a LAN connection.

ST offers a wide range of products suitable to cover the needs of power distribution unit. These products include power management ICs, microcontrollers and a variety of environmental sensors.
