Welcome to our store! 1. 3-stage PWM charging algorithm: Equalizes the battery periodically or upon over-discharge, effectively preventing the battery from becoming uneven and sulfating to extend battery life. 2. Features: With temperature compensation, it is used to adjust charging parameters automatically. A wide range of load working modes facilitates application to different types of loads. 3. Multiple Protections: With overcharge, over-discharge, overload protection, as well as short-circuit protection. 12V/24V system voltages are automatically recognized. 4. Large Load Start: Thanks to an advanced load starting method, large capacitance loads can be started smoothly. With an industrial-grade design, it can perform well under various harsh conditions. 5. Convenient to Use: TVS lightning protection, a dot-matrix LCD display, and a one-key man-machine interface. The user-friendly browser and dynamic interfaces ensure convenient and intuitive operations.
