Context

Power is a foundational element of data centre operations. Without a highly reliable power source, data centre operators cannot ensure the availability and performance of IT systems. That’s why the power distribution unit (PDU) is one of the most important components of the data centre infrastructure. A power distribution unit , or PDU, distributes continuous network power to multiple devices. A PDU doesn’t condition or generate power but relays AC power from a generator, an uninterruptible power supply (UPS), or a utility power source to networking hardware, servers, telecom equipment, and other critical devices.

Evidence

Pending intelligence enrichment.

The job of a PDU is to bring power from a primary electrical source into the data centre. Floor-mounted PDUs, also known as main distribution units, can supply 300kVA or more to power multiple racks and cabinets. Standard-density rack mount PDUs are generally rated up to 5kW, and high-density PDUs up to 10kW. There are also ultra-high-density PDUs for even greater power loads. PDUs are engineered for installation in special equipment racks, conveniently keeping power within reach of rack-mounted devices like routers, services, switches, or cooling fans. PDUs are typically employed in data centres, VoIP phone systems, network closets, and industrial environments.
