Product identity

The APC SUM48RMXLBP2U is a 48 V DC extended-run battery pack designed for Smart-UPS XL modular systems. It supplies 1300 VA capacity through two user-replaceable VRLA cartridges in a rack/tower convertible enclosure.

Capacity and headroom

Two hot-swappable modules deliver 1300 VA of backup power for compatible 1500 VA and 3000 VA Smart-UPS XL units. Runtime scales with load; the pack will exhaust its reserve faster under heavier draws and cannot support units outside the listed SUM series.

Thermals noise and power

Valve-regulated lead-acid cells operate without active cooling, so the pack adds no fan noise to the rack. The sealed cartridges weigh 131 lb and measure 3.4" high by 17" wide by 26.7" deep, requiring adequate rack space and structural support for safe installation.
