Power Distribution Unit (PDU)

Power Distribution Unit (PDU)

A power distribution unit (PDU) is a device that distributes electrical power to multiple devices within a data center or server room. They are essential for managing power distribution, ensuring reliable power delivery, and often include features for monitoring and controlling power consumption. They distribute electrical power from a single source to servers, storage systems, networking gear, and other IT equipment. They also ensure optimal load management and prevent overloads.
