Description
The Vertiv Liebert PSI5 48V External Battery Cabinet (PSI5-48VBATTTAA) is designed to extend runtime for compatible Liebert PSI5 TAA-compliant UPS systems, delivering enhanced power availability for critical IT and network applications. Engineered for seamless integration, this external battery cabinet connects directly to supported PSI5 UPS models to provide longer backup durations during extended outages.
Built with a compact rack/tower-convertible design, the cabinet fits easily into space-constrained environments such as network closets, edge installations, and small data centers. Its TAA compliance makes it ideal for government, defense, and regulated environments requiring adherence to federal procurement standards.
Ideal for deployments where uptime is critical, the PSI5 48V battery cabinet enables scalable runtime expansion without replacing existing UPS infrastructure.
