What is the primary function of a power distribution unit (PDU)?

The primary function of a power distribution unit (PDU) is to distribute electrical power to multiple devices or circuits. A PDU serves as a centralized point for managing and distributing power in situations where there are numerous devices that need to be powered, such as data centers or server rooms. It allows for efficient power management, ensuring that the electrical supply is appropriately distributed, which helps prevent overloads and maintains proper functionality of the connected equipment.

In addition to distributing power, PDUs often include features such as surge protection and circuit monitoring, which enhance their effectiveness. However, the main role remains focused on power distribution, making it crucial for operations that rely on numerous electronic devices needing stable and consistent energy supply. This distinguishes the PDU from other devices that specifically focus on power conversion, energy monitoring, or providing backup power.
