General-purpose Vertiv Liebert UPS for office, retail, and small business — PSI5 line-interactive, GXT5 online, GXT5 Lithium for long-deployment. 750 VA to 6 kVA on 120 V or 208/230 V. 2-year factory warranty (USA & Canada).
The general-purpose tier covers Vertiv Liebert UPS that doesn't sit at the data-centre extreme — not three-phase APM2 / EXM / NXC. The middle: workstation-to-small-server, retail back-of-house, branch-office IT, edge compute. Covers most Canadian SMB Vertiv purchases.
UPSPLUSBATTERY.CA stocks the general-purpose Liebert range with matching Liebert Vertiv replacement batteries. For topology-specific browsing see Vertiv line-interactive UPS and Vertiv online UPS. Full Vertiv catalog at Vertiv UPS.
