Description
The Vertiv Liebert PSI5-1000RM1201U is a high-performance 1U rackmount line-interactive UPS designed to protect critical IT and network equipment in space-constrained environments. Delivering 1000VA / 900W of reliable power, it features pure sine wave output on battery, making it ideal for servers, network switches, storage devices, and VoIP systems.
Advanced Automatic Voltage Regulation (AVR) with buck and boost functionality stabilizes incoming power without draining the battery, extending battery life and ensuring consistent output during voltage fluctuations. The compact 1U form factor includes a rotatable LCD display, programmable outlet group, and hot-swappable internal batteries for easy maintenance.
With USB connectivity and support for optional SNMP network management, the PSI5-1000RM1201U provides enterprise-grade power protection, monitoring, and flexibility for modern IT racks and edge deployments.
