Vertiv Liebert PSI5 UPS - 1100VA/990W 120V|Line Interactive AVR Tower/Rack Mount

The Vertiv Liebert PSI5-1100RT120 uninterruptible power supply provides dependable backup power and protection for servers, networking equipment, workstations, and other critical electronics in home, school, and office environments. This 1100VA/990W line-interactive UPS helps protect connected devices from outages, brownouts, sags, surges, and electrical noise while supporting orderly equipment shutdown during extended power interruptions.

Automatic Voltage Regulation (AVR) corrects input voltage fluctuations from 83 to 159 VAC without relying on the battery, helping conserve battery capacity and extend service life. Pure sine wave output supports sensitive IT equipment and critical applications, including network closets and small data centers. With a transfer time of less than 6 milliseconds, the Vertiv Liebert PSI5 is designed to provide responsive battery backup when utility power is disrupted.

The rack/tower form factor supports flexible deployment, while the rotatable LCD display provides convenient access to real-time operating conditions, alarm notifications, and runtime information. An optional Vertiv Liebert Unity communication card enables remote monitoring of up to 50 UPS systems through the Vertiv Trellis Power Insight application. The unit includes tower support stands, a USB Type A to USB Type B cable, a printed quick-start guide with safety instructions, and a CD.
