The BCU-4830A/BCU-4875A (48 V DC) battery chargers are designed for safe battery backup and shared energy use of the BOUTIQUE system and external power amplifier.

Battery chargers are microprocessor-based devices designed to charge lead-acid batteries and monitor the battery's status simultaneously. With the battery balancing function, the BCU-4830A/BCU-4875A battery charger can maximize the utilization of the 4 battery cells' capacity and increase their longevity.

The BCU-4830A network power output is max. 30 A and BCU-4875A is max. 75 A, with a maximum charging current of 3 A for BCU-4830A and 6 A for BCU-4875A. The BCU-4830A/BCU-4875A is equipped with contact outputs for remote monitoring and measures battery resistance to ensure whether the battery is functioning or not. Additionally, the BCU-4830A/BCU-4875A will detect and control the battery charging action through the temperature sensor, thus extending the battery's lifespan.
