To minimize possible differences in potential in the grounding systems for power circuits supplying IT equipment, it is common for these centers to be equipped with a single or multiple power distribution units (PDUs). Each rack must safely deliver stable electrical power to dozens of servers, switches, and storage devices while maintaining reliability, airflow efficiency, and electrical safety. Article 645 of the National. A power distribution unit (PDU) is a device fitted with multiple outputs designed to distribute electric power, especially to racks of computers and networking equipment located within a data center. Data centers face challenges in power protection and management solutions. Modern data centers rely on intelligent PDUs equipped with monitoring, control, and protection capabilities to. Designing an efficient electrical distribution system and power supply for a data center isn't just about delivering electricity—it's about achieving high reliability, handling high power densities, minimising power outages, and optimising for energy performance (e.
