Taihang Jiaxin lead-acid battery charging system is suitable for maintenance and non-maintenance operations. The primary function of the charging system is to provide continuous load while charging the battery without supervision. It is suitable for high reliability emergency backup power systems. Controlled by solid state thyristors with electronic sensing and monitoring. The charging characteristic is a constant potential with a current limit. The primary function of the charging system is to provide continuous load while charging the battery without supervision. The charger rectifier circuit provides 100% of the rated current, while the float/boost charges a group of lead acid batteries.
