Description

The Vertiv Liebert PSI5 1500VA Rack/Tower UPS delivers high-performance, line-interactive power protection for critical IT and network applications. Designed for flexibility, this 2U convertible UPS supports both rack-mount and tower installations, making it ideal for network closets, edge deployments, and small data centers.

With Automatic Voltage Regulation (AVR) and pure sine wave output, the PSI5 ensures stable, clean power while extending battery life during utility fluctuations. A 0.9 power factor provides more usable output power, allowing you to support higher-density equipment without oversizing the UPS.

Advanced features include hot-swappable batteries, programmable outlet groups, USB connectivity, and support for optional SNMP/network management cards. The PSI5 1500VA also supports external battery cabinets for extended runtime, giving organizations the scalability and reliability needed to keep systems online during outages.
