The CyberPower BP240V30ART3U (240V) External Battery Module (EBM) with DC plug-n-play connections provide extended battery run-time during power outages for select Smart App Online UPS models. Fast charging times are maintained thanks to a built in battery charger. The typical charging times of 4 hours is maintained even when additional EBMs are installed. Each EBM takes up 3U of rack space and can also be installed in a tower form factor to match the UPS power module. The back panel includes an access panel to the fuses for easy replacement, a resettable circuit breaker to protect against overloads, and a DC breaker to safely remove power from the batteries when connecting or disconnection the EBM. A DC plug-n-play power connector and an AC receptacle for the battery charger make it easy to “daisy-chain” additional EBMs to a UPS system. A Three-Year Warranty ensures that the BP240V30ART3U has passed our highest quality standards in design, assembly, material or workmanship.
