ABSTRACT:
Apparatuses, systems, and methods for providing battery-backed power to movable partitions are disclosed. A power converter generates a DC output from an AC input. The DC output may be selectively decoupled from an enabled DC output such that the DC output can be monitored for acceptable operation in-situ. The enabled DC output may be selectively coupled to a battery output terminal. A charge current may be sensed between the enabled DC output and the battery output to control charging of the battery with a pulse-width modulation operation by controlling the selective coupling of the enabled DC output to the battery output. The enabled DC output and the battery output are coupled in a logical-OR configuration to generate a supply output providing current from the enabled DC output and the battery. The supply output may drive a movable partition controller and a motor configured for opening and closing a movable partition.
