Applications
The UP-9125 is a line-interactive UPS typical of the late 1990s–early 2000s, designed to protect workstations, servers, and other sensitive electronic equipment from power interruptions, sags, and surges. Units of this class were commonly deployed alongside proprietary workstation platforms — in the case of the Unisys UP-9125, it was paired with Unisys enterprise workstations and servers. The 1250VA/900W rating makes it suitable for powering midrange server or workstation loads. Today, units like this are sought after by technicians for parts, battery-case reuse, or repair projects, as the UPS electronics (inverter, transfer switch, control circuitry) are often intact even when the original battery has reached end of life.
This Unisys UP-9125 Uninterruptible Power Supply is being sold AS-IS for parts or repair. No battery is included — this UPS requires a proprietary battery pack, which may use a non-standard connector, and is not provided. The unit has a crack in the plastic housing at the rear corner, visible in the photos. It has not been tested and is not guaranteed functional. Please view our photo set and contact us if you have any questions.
