Vertiv Liebert PSI5 3000 2700W 120VAC RT with RDU120 Card | Rack Mount UPS

Maintain uptime for essential rack-based systems with the Vertiv Liebert PSI5 3000. Built for 120 VAC environments and rated at 2,700 W / 3,000 VA, it delivers the capacity needed for higher-density network closets, branch infrastructure, and small server deployments. The rack/tower design gives you deployment flexibility when floor space, cabinet depth, or service access drives the installation plan. This model includes an RDU120 card, adding remote monitoring capability that helps IT teams track UPS status without standing at the rack. That matters when the UPS is protecting equipment that cannot tolerate unplanned downtime or when support teams need faster insight during an event. The PSI5 platform is a practical choice when you want more than basic battery backup: it is sized for serious loads, built for controlled deployment, and suited to environments where power quality and manageability directly affect service continuity. For teams comparing entry-level units with higher-value infrastructure protection, this configuration stands out by combining capacity, rack/tower versatility, and remote visibility in one package.
