Vertiv PSI5-1500MT120 Line-Interactive UPS

Overview

The Vertiv Liebert PSI5-1500MT120 is a line-interactive UPS with Automatic Voltage Regulation (AVR) designed to provide reliable backup power and surge protection for sensitive electronic equipment. Its compact mini-tower form factor makes it suitable for deployment in environments where space is limited, such as server closets, network racks, or workstations. This unit ensures continuous operation during minor voltage fluctuations and provides battery power during outages, safeguarding against data loss and equipment damage. The PSI5-1500MT120 offers up to 1440 VA / 1350 W of power capacity and features an LCD display for easy status monitoring and configuration.

Compatibility

This UPS is designed to support a wide range of IT and surveillance equipment. It is compatible with standard 120VAC input and provides six 5-15R outlets for connected devices. The unit's input voltage range of 75-146VAC allows it to operate through common power sags and surges without depleting battery reserves. Optional communication cards (IS-UNITY-SNMP, IS-UNITY-DP) enable SNMP and web management, integrating it into existing network monitoring systems. It is suitable for protecting workstations, network switches, small servers, and surveillance NVRs.

Installation Notes

The Vertiv Liebert PSI5-1500MT120 operates within an ambient temperature range of +32 to +104 °F (0 to 40 °C). It features a standard 5-15P input plug and provides six 5-15R output receptacles, simplifying connection to typical IT equipment. The unit supports user-configurable output voltages of 100/110/115/125VAC, allowing for precise power delivery. For advanced management, it includes USB and RJ-45 ports, alongside EPO (Emergency Power Off) terminals. The line-interactive topology with AVR ensures stable power output by correcting voltage variations without switching to battery unless necessary, maximizing battery life.
