Vertiv Liebert PSI5 3,000 VA 2,700 W Rack Mount UPS | SNMP, TAA

Maintain uptime where it matters most with the Vertiv Liebert PSI5 3000. This rack-mount UPS delivers 3,000 VA and 2,700 W of capacity for protecting servers, storage, network switches, and other critical rack equipment from outages, sags, and surges. Its line-interactive topology helps correct common power problems without constantly switching to battery, preserving runtime for the events that actually threaten availability. Built for IT environments that need more than basic backup power, the PSI5 includes SNMP manageability for remote monitoring and coordinated response. That matters when racks are distributed, closets are unattended, or shutdown windows are tight. The 120 VAC output aligns with standard North American infrastructure, while the rack-ready form factor keeps valuable floor space free. For teams comparing UPS options, this model stands out by pairing enterprise-grade capacity with the operational visibility needed to support higher-value workloads. It is a practical fit for environments where downtime is expensive, equipment density is high, and power quality cannot be left to chance. TAA compliance also makes it suitable for procurement paths that require it.
