A Power Distribution Unit (PDU) is a device designed to manage and distribute electrical power to multiple devices within a data center, server rack, or network infrastructure. PDUs provide an efficient way to distribute electricity from a single power source to multiple servers, switches, and other equipment, ensuring balanced power loads. They come in various types, including basic, metered, and intelligent PDUs, with the latter offering advanced monitoring, remote management, and load balancing. PDUs enhance power efficiency, prevent overloads, and improve operational reliability in high-demand environments like data centers, optimizing energy use and equipment performance.
