Vertiv Liebert PSI5 3,000 VA 2,700 W UPS | Rack Mount TAA Enterprise

Keep critical systems online with the Vertiv Liebert PSI5-3000RT120TAA, a 3,000 VA / 2,700 W rack-mount UPS designed for 120 V infrastructure. It is a strong fit for IT teams that need dependable power protection for servers, storage, and network gear without moving to a larger, more complex power architecture. TAA compliance makes this model especially relevant for public sector and regulated procurement environments where sourcing requirements matter as much as technical fit. The 120 V input and output profile aligns with common North American deployments, while the rack-mount design helps preserve valuable floor space in closets, branch sites, and smaller data rooms. This UPS is sized for the point where downtime becomes expensive and basic consumer-grade protection is no longer enough. It gives infrastructure teams a practical way to ride through short outages, bridge generator transfer events, and complete controlled shutdowns when runtime is exhausted. For organizations that need a credible UPS with procurement-ready credentials, the PSI5 line offers the right balance of capacity, deployment simplicity, and enterprise positioning.
