Eaton Corporation has released 480-volt (V) configurations for its ePDU power distribution product line. The new units are designed to help achieve efficiency gains in large enterprise data centers where high-density computing is required. The majority of Eaton’s three-phase uninterruptible power supplies, including the Eaton 9355, 9390, and 9395, are designed to work seamlessly with a 480-V ePDU solution.
Since utility power in North America typically enters a facility at 480-Vac, Eaton’s 480-V ePDU products remove the need for step-down transformers. A server operating at 277-V requires 25 percent less current than a server operating at 208-V. This allows for a reduction in upstream circuits, which reduces overall copper and power distribution costs.
