STB65 Forward and Reverse Control Battery Charger Control Board

STB65 battery charge control trigger board adopts 32-bit industrial grade high-performance microprocessor, highly digital military quality design, supports network remote control and on-site control mode. The fuzzy-PID parameter is open-ended, fault alarm and parameters are displayed on the LCD screen or touch screen menu Chinese, parameters are automatically saved after setting. With constant voltage and constant current regulation, the charging operation parameters are set by the LCD screen. The charging phase can be set up in four stages, each stage are set independently: charging current, charging voltage, current limit, charging time and jump voltage, support one-stage discharge parameter setting, users can set the charging parameters of pre-charging, fast charging, slow charging or floating charging according to the current battery charging curve freely. The operation is reliable, technology is advance, functions are complete, performance is stable, debugging is convenient and easy to maintain.
