Vertiv PROREF PL PSI5X1100 MULTI 1,100 VA Desktop UPS | Enterprise Power

Keep critical desktop workloads online when utility power becomes unreliable. Vertiv PROREF PL PSI5X1100 MULTI is built for environments that need compact, dependable backup power without adding rack complexity. Its 1,100 VA class makes it a strong fit for workstations, small servers, network appliances, and point-of-sale systems that cannot afford abrupt shutdowns. This model is designed to do more than bridge outages. It helps condition incoming power, reduce the impact of sags and surges, and give connected equipment time to shut down cleanly during extended interruptions. For IT teams, that means fewer corrupted files, fewer service calls, and less risk to hardware that sits close to the edge of the network. The desktop form factor makes deployment straightforward in branch offices, service counters, and back-office spaces where floor and rack space are limited. For buyers comparing entry-level protection against a more capable UPS class, this model offers a stronger fit when the workload is business-critical and the cost of downtime is higher than the cost of added power protection.
