Extended Runtime for SRT UPS

The APC Smart-UPS SRT48RMBP is a 48V 1.5kVA replacement battery pack designed for rack-mount Smart-UPS on-line systems. It provides stand-alone battery backup to keep mission-critical applications running during prolonged outages. This unit targets administrators who need to extend runtime on existing SRT deployments without replacing the entire UPS.

Sustained Discharge and Monitoring

Embedded monitoring reports health at cell, module and cabinet levels so operators can track remaining runtime during extended loads. The pack operates continuously from 0 to 40 degrees Celsius and up to 10000 feet elevation. Storage tolerates -15 to 45 degrees Celsius and 0 to 95 percent relative humidity, allowing the batteries to survive harsh facility conditions between deployments.

Rack Installation and Constraints

The 2U form factor measures 3.35 by 17.00 by 21.10 inches and weighs 65.92 pounds, so two-person handling or a lift is advisable when sliding it into a standard rack. Buyers who need a different voltage, a tower form factor or a smaller capacity cannot use this pack. No cables or rail kits are mentioned in the specifications, so verify compatibility with your existing SRT chassis before ordering.

Questions about this item

Does the SRT48RMBP generate noticeable noise or heat when running continuously in a 40 °C rack environment?

The battery pack operates silently with no fans; it is rated for 0–40 °C ambient temperature and 0–95 % relative humidity during continuous operation.

Which APC UPS models must I already own for the SRT48RMBP to function as an extended-runtime pack?

It is designed for Smart-UPS SRT on-line systems rated at 48 V — specifically the 1 kVA and 1.5 kVA rackmount models.

Will the SRT48RMBP work alongside an older Smart-UPS RT unit that uses the same 48 V battery voltage?

No — the pack integrates only with current SRT-series on-line UPS units; legacy RT models use a different mechanical and communication interface.
