Inside each rack, the Power Distribution Unit (PDU) plays a central role. A PDU converts a single incoming power connection into multiple outlets for IT equipment. Most modern installations use vertical PDUs mounted along the rear of the cabinet frame. This article explores how power is connected inside modern data center racks, examining the flow of electricity. When people think of a data center, their attention usually goes straight to server racks, blinking LEDs, and high-performance computing hardware. It generally includes redundant or backup power supplies, redundant data communications. In Europe, EU Regulation 2024/573 sets phased restrictions for new fluorinated-gas switchgear by voltage class, so project teams should check the specific deadline that applies to the selected MV or HV range rather than using one generic “phase-out” date. If you want to build and operate your AI data center as effectively and efficiently as possible.
