Eaton PDUB151U – 100-125V Hot-Swap Bypass PDU, 1U

Product Overview

The Eaton PDUB151U is a 100-125V, 12A single-phase hot-swap PDU with manual bypass, designed to keep mission-critical data center equipment powered during scheduled UPS maintenance or replacement. Working alongside an existing UPS system, this 1U rack or wall-mount PDU lets technicians manually transfer connected equipment to utility power via a bypass switch, avoiding the downtime that a full power-down would otherwise require.

Product Description

Scheduled UPS maintenance is often unavoidable in a data center, but powering down connected equipment to perform it is rarely acceptable when uptime is mission-critical. The PDUB151U solves this by allowing staff to manually transfer connected equipment to utility power through the PDU's bypass switch, permitting UPS maintenance or replacement with no interruption to running equipment. The unit provides six NEMA 5-15R outlets for connecting servers, switches, or other rack-mounted devices, and accepts dual NEMA 5-15P inputs so it can draw power from both the UPS output and a separate utility or bypass source. Built for 100-125V single-phase environments at 12A, the PDUB151U installs into 1U of a standard 19-inch rack or can be wall-mounted, giving integrators flexibility depending on available space in the equipment room. This hot-swap bypass PDU is recommended for data centers and other mission-critical environments where continuous 24/7/365 uptime during UPS maintenance windows is a requirement rather than a nice-to-have.
