Uninterruptible Power Supplies

A power distribution unit, PDU, is a critical piece of equipment designed with multiple outputs that distribute electrical power and is typically used in data centers. They are designed to control power requirements that are much larger than home or office power strips and surge protectors. The power requirement in data centers can be as large as 22 kVA or more.

Data centers rely on power distribution units to improve uptime and efficiency and support growth. Most large data centers require PDUs with single-phase power output and three-phase power input.

Types of Power Distribution Units

There are basically two main types of PDUs, basic and monitored, or intelligent PDUs.

  • Basic PDU – a basic PDU is simply designed to distribute power from the input and provide standard electrical outlets to data center equipment. They are normally installed directly on a rack, and basic rack power distribution units may resemble a large power strip without surge protection. They do not provide advanced features.
  • Monitored PDUs – monitored PDUs are intelligent with capabilities such as real-time monitoring and remote access management. They are networked and normally contain an intelligence module that allows for remote metering of power information as well as on-off control and alarms. Some advanced power distribution units allow users to manage external features such as airflow, temperature, and humidity.


PDUs are typically installed directly on a rack, and rack power distribution units can utilize a power source coming from either alternating current (AC) or direct current (DC) power. The power can originate from an uninterruptible power supply (UPS), a generator, a utility power supplier, or a secondary power source.
