Bypass PDU Recommended for Maintaining Continuous Power During UPS Maintenance
Keeping mission-critical data center equipment operating at its optimal level often means scheduled
maintenance. But what if you are unable to afford the costly downtime involved in powering down for
regular upkeep? This 120V 20A single-phase hot-swap PDU works in conjunction with your UPS system
to keep everything running 24/7/365. It allows you to manually transfer connected equipment to utility
power via the PDU’s bypass switch, permitting maintenance or equipment replacement with no
interruption of performance.

Features Dual Inputs and a Manual Transfer Switch for Uninterrupted Operation
The PDUB201U includes separate UPS and utility input cables with NEMA 5-20P plugs. The manual
transfer switch allows PDU output power to flow from either input. Flip the switch to Bypass to replace the
UPS and flip back to Normal once the maintenance or UPS replacement is complete. Equipment
connected to the six NEMA 5-20R outlets will continue to operate without interruption.

Optional ECO Switching Feature Enables Cost-Cutting Power Savings
By enabling the ECO power saving feature, you can power off a single bank of five controlled 5-20R
outlets all at once when the device connected to the master 5-20R outlet is powered off or goes into a lowpower consumption mode.

Mounts into 1U of Rack Space or Wall
Use the included mounting hardware to install the PDUB201U’s all-metal housing into 1U of space in an
EIA-standard 19-inch rack. You may also use the mounting brackets to secure the PDU to a wall.
