STB63 controlled three-phase bridge rectifier module - the secret to a perfect three-phase battery charging system!


Three-phase rectifier battery charging control module STB63

6 3-phase pulses, LCD interface, 4 charging stages, support 1-stage discharge setting, 380V input, 1000A activation capacity.



STB63 3-phase bridge rectifier module with thyristor control uses high-end industrial 32-bit microprocessor, military-quality digital design, supports remote control via network and on-site control. Fuzzy-PID parameter is open-ended, error alarm and parameters are displayed on LCD screen or Chinese touch screen menu, parameters are saved automatically after setting. With constant voltage and constant current regulation, charging operation parameters are set using the LCD display. Charging stage can be set into four stages, each stage is set independently: charging current, charging voltage, current limit, charging time and jump voltage, support single-stage discharge parameter setting stage, users can set the charging parameters of pre-charging, fast charging, slow charging or floating charging according to the current battery charging curve freely. Reliable operation, advanced technology, complete functions, stable performance, convenient debugging and easy maintenance.
