Alternating Current Power Distribution Unit (AC PDU) Definition

"PDU" Definition
The acronym "PDU" stands for Power Distribution Unit. PDUs are, essentially, industrial-grade power strips used (in most cases) to power servers and telecommunications equipment.

You'll generally have too many devices at a site to plug them all directly into your power supply. You need PDUs to distribute your site's power to each device. This is possible because a PDU turns one (or a few) power inputs into many (usually about eight) power outputs.

PDUs are available in both AC and DC models to match the power in use at different kinds of sites.

AC PDUs are built just like their DC-power counterparts, except for their output current.

AC power distribution units are designed to provide electric current in the Alternating Current format that many rack-mounted devices use.
