Overview

The Vertiv Liebert PSI5-1000RM1201U is a 1,000 VA / 900 W line-interactive UPS designed for rackmount deployments. It provides conditioned power with automatic voltage regulation (AVR) to protect sensitive IT equipment from voltage fluctuations and short-term outages. Its compact 1U form factor makes it suitable for densely populated server racks where space is at a premium, ensuring continuous operation for critical network devices, switches, or servers.

Compatibility

This UPS is designed to support standard 120VAC IT equipment. It features a 5-15P input plug and five 5-15R outlets, compatible with most common server and network peripheral power cords.

It is suitable for use with standard rack-mounted servers, network switches, and other 120V equipment requiring stable power.

Installation Notes

The unit operates within an ambient temperature range of +32 to +104 °F (0 to 40 °C). It requires a standard 5-15P wall outlet for input power. The UPS is rated ANSI C62.41 Category A, Level 3 for surge protection. Its line-interactive topology with AVR corrects voltage variations without switching to battery, preserving battery life during minor fluctuations. The front-panel LCD display provides immediate insight into UPS status, configuration, and operational parameters.
