Deliver backup power where rack space is tight and uptime still matters. The Vertiv Liebert PSI5 1500 1350W, 120VAC is designed for infrastructure teams that need dependable protection for network gear, edge systems, and compact server deployments without giving up valuable rack units. With 1,500 VA and 1,350 W of capacity, it is sized for essential loads that must stay online through short outages and utility disturbances. The 120 VAC design aligns with common North American power environments, while the rack-mount format keeps installation clean and predictable in standardized cabinets.
