General Overview:
Three-phase dual 6-pulse, LCD interface. Four charging stages: pre-charge, fast charge, slow charge, or float charge, and supports single-stage discharge setup. Input 380V, activation power 1000A.
Features:
The STB65 battery charging control activation board uses a high-performance 32-bit industrial-grade microprocessor and high-quality military-grade digital design, supporting both remote network control and on-site control modes. The fuzzy PID parameters are open-loop; fault alarms and parameters are displayed on the Chinese touch screen or LCD menu, and the parameters are automatically saved after setup. With constant voltage and constant current regulation, charging operation parameters are set via the LCD screen. The charging stages can be configured into four stages, with each stage set independently: charging current, charging voltage, current limit, charging time, and jump voltage. It supports single-stage discharge parameter setup, allowing users to freely configure pre-charge, fast charge, slow charge, or float charge according to the current battery charging curve. Reliable operation, advanced technology, comprehensive functions, stable performance, convenient debugging, and easy maintenance.
