Description
The Vertiv Liebert PSI5-1500MT120N is a high-performance line-interactive UPS designed to protect critical IT and network equipment in space-constrained environments. Built in a compact mini tower form factor, it delivers 1500VA / 1350W of reliable power protection with pure sine wave output, making it ideal for servers, network devices, and sensitive electronics.
This model features Automatic Voltage Regulation (AVR) to correct brownouts and overvoltages without switching to battery, extending battery life and maximizing uptime. Integrated network connectivity enables remote monitoring and graceful shutdown, while hot-swappable batteries simplify maintenance and reduce downtime.
Engineered for branch offices, network closets, and edge deployments, the PSI5-1500MT120N combines efficiency, manageability, and enterprise-grade protection in a compact footprint.
