Product Overview
The APC SRT48RMBP is a 48V extended runtime battery pack engineered to add backup time to APC Smart-UPS SRT 1kVA and 1.5kVA online double-conversion systems. As a dedicated APC Smart-UPS SRT battery pack, it lets AV and IT teams scale runtime for head-end equipment without replacing the UPS. This rack-mount extended runtime battery pack matches the SRT chassis for clean integration into a commercial AV rack. It is the factory-matched answer for facilities that need longer ride-through during utility events.
Product Description

The SRT48RMBP provides extended runtime for critical Smart-UPS SRT applications by adding reliable lead-acid battery capacity at a nominal 48V. It is designed for rack-mounted installations, so it slides into the same AV rack or server rack as the host SRT UPS. The enclosure measures 8.5 cm in height, 43.2 cm in width, and 53.6 cm in depth, fitting standard rack widths used in commercial AV and IT deployments. Multiple packs can be added to a compatible SRT system to tailor runtime to the load. The unit is a genuine APC replacement battery solution, listed as the supported battery for the 1kVA and 1.5kVA SRT models. Because it uses the SRT connection scheme, installation does not require rewiring the protected equipment. This makes it a practical choice for integrators maintaining boardroom, control-room, and head-end power systems. It ships as a defined battery enclosure ready to connect to the host UPS.
