Description
The Vertiv Liebert PSI5-500SRT1ULIN is a compact, high-performance 1U line-interactive UPS designed to protect critical IT and network equipment in space-constrained environments. Powered by long-life lithium-ion batteries, this UPS delivers faster recharge times, significantly longer battery life, and reduced maintenance compared to traditional lead-acid systems.
With a 0.9 output power factor, pure sine wave output, and wide input voltage range, the PSI5 ensures stable, efficient power for edge IT, network closets, and remote deployments. Its short-depth rack/tower convertible design supports flexible installation, while the included network management card enables remote monitoring, alerts, and graceful shutdown of connected equipment.
Backed by a standard 5-year warranty and a $400,000 equipment protection plan, the PSI5-500SRT1ULIN provides reliable, low-TCO power protection for mission-critical applications.
