Vertiv Liebert PSI5 1500VA 2U Lithium-Ion UPS | Rack Tower, TAA

Deliver dependable backup power in a compact chassis built for distributed IT environments. The Vertiv Liebert PSI5 Lithium-Ion TAA 1500VA provides 1,500 VA / 1,350 W of capacity in a 2U rack/tower design, making it well suited for branch offices, network closets, and edge racks where space is tight and uptime is non-negotiable. Lithium-ion battery technology helps reduce the maintenance cycle associated with traditional UPS batteries, while the included RDU120 card gives administrators remote access to UPS status and alerts. That combination is valuable when the unit is protecting switches, firewalls, storage, or a small server stack that must stay online through brief outages and power disturbances. The 120 V class aligns with standard North American power environments, and the TAA-compliant designation supports procurement requirements in regulated or public-sector buying processes. For teams that want monitored power protection without overbuying capacity, this model offers a focused specification set that fits real-world edge deployments and justifies its place in a premium infrastructure standard.
