External Battery Cabinet

The Emerson Network Power PSI524VBATT is a 24V valve-regulated lead-acid battery cabinet designed to extend runtime for compatible UPS units. It connects directly to the PSI5-800RT120 and PSI5-1100RT120 models for network closets and small data centres.

24V Battery Capacity

The cabinet adds battery headroom so connected UPS systems can support servers, routers and critical nodes through longer outages. Runtime scales with the load on the host UPS; the cabinet itself has no independent output or inverter.

Pre-Wired Battery Module

The unit arrives as a sealed, maintenance-free battery pack with cabling for immediate connection to the matching PSI5 UPS. No extra software, rail kit or management card is included in the package.
