Generality:
 
3 phase 12 pulse, LCD interface. The four charging steps are pre-charge, fast charge, slow charge or drift charge, users can freely set it up as they like. Input 380V, trigger capacity 1000A.
Featured:
STB66 battery charge control trigger board uses 32-bit industrial-grade high-performance microprocessor, high digital military quality design, supports network remote control and on-site control mode . The fuzzy PID parameter is open-ended, error warning 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, the charging operation parameters are set by 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 discharge parameter setting one stage, users can set the charging parameters of pre-charge, fast charge, slow charge or drift charge according to the current charging curve freely. Reliable operation, advanced technology, complete functions, stable performance, convenient debugging and easy maintenance.
