The Taihang Jiaxin charger is controlled by a solid-state thyristor with electronic sensing and monitoring functions. The main function of the charging system is to charge the battery without supervision while providing a continuous load. The charging characteristic is a constant potential with a current limit. The charger rectifier circuit provides 100% of the rated current, while the float/boost charges a group of lead-acid batteries. The system is also suitable for maintenance and non-maintenance operations.
