Vertiv Liebert PSI5 3000VA 2700W Rack-Tower UPS | 2U, Enterprise

Maintain uptime for critical infrastructure with the Vertiv Liebert PSI5 3000VA/2700W rack-tower UPS. Built for 120 VAC environments, it delivers line-interactive power conditioning for servers, network switches, storage arrays, and edge systems that cannot tolerate unstable utility power. The 2U rack-tower design gives you deployment flexibility in standard racks or as a tower where floor space and service access matter. With 3,000 VA and 2,700 W of capacity, this model is sized for higher-density loads that outgrow entry-level UPS units. It includes six NEMA 5-15R outlets and one NEMA L5-20R outlet, giving you the right mix for mixed IT equipment and higher-draw devices. Support for 115 V AC, 120 V AC, and 125 V AC input helps it fit common North American power conditions without forcing a redesign of the electrical path. For teams that value predictable recovery and clean power delivery, the PSI5 line is a practical choice when downtime costs more than the hardware. It is designed to protect connected equipment from interruptions while preserving rack efficiency and simplifying deployment in enterprise, branch, and edge environments.
