Power Distribution Units (PDUs) are available in several types, each designed to meet varying power distribution requirements within IT infrastructures. Selecting the appropriate type of PDU depends on system size, equipment demand, and the level of power control needed within the facility.

Basic PDUs

Standard PDUs offer straightforward electrical distribution. These units do not include monitoring or switching capabilities. They are typically used in compact server rooms where equipment demand is stable and does not require real-time oversight. Basic PDUs are cost effective and support consistent power delivery across connected devices.

Metered PDUs

Load-Metered PDUs enable facilities teams to view electrical load information directly from the unit. A display panel shows how much power is being drawn by connected equipment. Tracking this information helps minimise the risk of exceeding circuit limits. Metered PDUs are often used in environments where power usage must be tracked across multiple racks.

Monitored PDUs

Networked PDUs provide remote access to load information through a network connection. IT teams can check power usage without visiting the cabinet physically. This assists with maintenance planning and system audits. Remote monitoring also enables facilities teams to identify unused capacity within power circuits.

Switched PDUs

Remotely Switched PDUs feature remote outlet control. Each socket can be turned on or off through a management interface. This allows technicians to restart servers or network devices if a system becomes unresponsive. Switched PDUs are often used in unmanned facilities or in distributed network environments.

Intelligent PDUs

Smart PDUs combine monitoring and switching features. These units provide real-time data on voltage, current, and power usage. Some models support environmental monitoring sensors that measure temperature and humidity levels. Intelligent PDUs are commonly used in larger data centres where system performance depends on accurate power management.

Automatic Transfer Switch PDUs

ATS PDUs support redundancy by connecting equipment to two power sources. If one source fails, the unit automatically switches to the backup supply. This feature helps maintain business continuity during power interruptions.

Rack Mounted PDUs

Rack mounted PDUs are built for installation within server cabinets. Zero-U units provide multiple outlets without occupying pdus rack unit space. Horizontal units fit within standard rack slots and are used where vertical mounting is not suitable.

Selecting the Right PDU

Choosing the correct PDU type helps ensure safe electrical distribution and equipment performance. Facilities teams should review equipment demand, load requirements, and maintenance processes before installing PDUs. Careful selection helps maintain uptime and ensures infrastructure reliability.
