Description
The Vertiv Liebert PSI5-1500SRT2UXLI is a high-performance, line-interactive lithium-ion UPS designed for edge IT, network closets, and space-constrained environments. Delivering 1500VA / 1350W of reliable power protection in a 2U short-depth rack/tower form factor, it provides clean, pure sine wave output to safeguard critical servers, networking equipment, and electronics.
Built with advanced lithium-ion (LiFePO₄) battery technology, the PSI5 offers up to three times longer battery life, significantly faster recharge times, and reduced maintenance compared to traditional VRLA UPS systems. Its high 0.9 output power factor ensures more usable power per rack unit, while the wide input voltage range minimizes battery usage and extends overall system lifespan.
Designed for flexibility and manageability, the PSI5-1500SRT2UXLI features a rotatable LCD display, programmable outlet groups, hot-swappable batteries, and optional IntelliSlot network management for remote monitoring and control. This UPS is an ideal solution for organizations seeking lower total cost of ownership without compromising uptime or performance.
