Product Overview

The ABP72VRM2U rack/tower convertible Extended Battery Module (EBM), which extends battery runtimes during power outages, is designed for Smart App Online UPS systems OL2000RMXL2U and OL3000RMXL2U. This EBM takes 2U of rack space and can be installed to rack or tower configuration to match the UPS form factor. Up to four EBMs can be added to the UPS, and the module's DC plug-and-play power connectors allow for daisy-chaining EBMs to a UPS system. The ABP72VRM2U typically has a UPS charging time of three hours. For estimated runtimes, see the Estimated Runtimes table. The ABP72VRM2U comes with a three-year warranty.

Higher Capacity UPS for Longer Runtimes

To determine the size of the UPS that you need, identify the total power load (measure in VA/Watts) of the connected equipment, along with the amount of runtime required (in minutes). Also, think about any equipment that might be connected to the UPS in the future, which could affect the calculations for load and runtime.

Estimating expected UPS runtimes can be challenging, particularly when the consistency of the utility power is not well known. Selecting a UPS with a load capacity 30-35% above the required power load offers the advantage of longer runtimes. This can lower the risk of overloading the UPS and causing an unnecessary UPS shutdown.

Although the initial outlay of a UPS increases with its size because of the higher capacity required for components, long-term operating costs typically decrease. When a UPS operates below maximum capacity, it reduces the stress on components. Sizing a UPS to run loads significantly lower than its capacity also increases spare capacity for future growth, along with extending runtimes.
