Vertiv Liebert PSI5 Lithium Io 3,000 VA 120 V Rack UPS | Enterprise

Keep critical workloads running through sags, outages, and unstable utility power with the Vertiv Liebert PSI5 Lithium Io. This 3,000 VA, 120 V line-interactive UPS is built for rack deployments where uptime, battery longevity, and remote oversight matter more than commodity protection. Lithium-ion battery technology reduces maintenance burden versus traditional VRLA designs, while programmable outlets give administrators more control over how backup power is allocated during an outage. For infrastructure teams supporting edge servers, network closets, and distributed IT, the PSI5 Lithium Io delivers the kind of power continuity that protects applications, storage, and communications equipment without adding unnecessary complexity. Remote management capability helps teams monitor and respond without a site visit, which is especially valuable when the UPS is deployed across multiple locations. The rack-mount form factor fits standard infrastructure environments and supports cleaner integration into existing power layouts. This model is a strong fit when you need more than basic battery backup. It is designed to preserve availability, reduce battery replacement cycles, and give administrators the visibility required to manage power as part of the broader infrastructure stack.
