Which Different Type of Power Distribution Unit Can Be Used in Data Centers?


Angela Bailey

In a data center, power distribution units (PDUs) play a crucial role in managing and distributing power to various equipment and devices. There are different types of PDUs available that offer unique features and functionalities. Understanding these different types of PDUs can help data center administrators make informed decisions when it comes to selecting the right one for their specific needs.

Basic PDUs

Basic PDUs, also known as strip or rack-mount PDUs, are the most common type of PDUs used in data centers. They provide a reliable way to distribute power to servers, networking equipment, and other devices within a rack. Basic PDUs typically come with multiple outlets and a single input power cord that can be connected directly to a power source.


  • Cost-effective solution for basic power distribution needs.
  • Straightforward installation and operation.
  • Compact design that saves valuable rack space.

Metered PDUs

Metered PDUs offer additional features compared to basic PDUs by providing real-time monitoring of power consumption. They come equipped with built-in meters that display important information such as voltage, current, power usage, and more. This allows administrators to keep track of power usage trends, identify potential issues, and optimize energy efficiency.


  • Accurate monitoring of power consumption helps prevent overloads.
  • Enables better capacity planning and resource allocation.
  • Data logging capabilities for analyzing historical power usage patterns.

Switched PDUs

Switched PDUs combine the capabilities of both basic and metered PDUs with the added ability to remotely control power outlets. These PDUs can be managed through a web interface or a central management system, allowing administrators to turn outlets on/off, monitor power usage, and configure advanced settings remotely.


  • Remote power control enables efficient troubleshooting and equipment management.
  • Individual outlet monitoring and control for enhanced flexibility.
  • Alert notifications for power events or abnormal conditions.

Monitored and Switched PDUs

As the name suggests, monitored and switched PDUs combine the features of both metered and switched PDUs. They provide real-time monitoring of power usage while also offering remote management capabilities. These PDUs are suitable for data centers that require both monitoring and control functionalities in a single unit.


  • Comprehensive visibility into power usage at individual outlets.
  • Flexible remote management options for efficient operations.
  • Integration with building management systems for centralized monitoring.

Dual-Circuit PDUs

Dual-circuit PDUs are designed to provide redundant power supply to critical equipment. They have two separate input power cords that can be connected to different power sources, ensuring continuous operation even if one circuit fails. Dual-circuit PDUs are commonly used in high-availability environments where uptime is of utmost importance.


  • Redundant power supply for increased reliability and fault tolerance.
  • No single point of failure, minimizing downtime risks.
  • Suitable for mission-critical applications that require uninterrupted operation.


Choosing the right type of power distribution unit is essential for maintaining a reliable and efficient data center infrastructure. Basic PDUs offer a cost-effective solution, while metered PDUs provide monitoring capabilities.

Switched PDUs enable remote control, and monitored and switched PDUs combine both functionalities. Dual-circuit PDUs ensure redundancy for critical equipment. By understanding the different types of PDUs available, data center administrators can make informed decisions that align with their specific requirements.
