13?Stage Pwm Charging Algorithm: Equalizing charging to the battery periodically or when over discharged, effectively prevent the battery from non?equalization and sulfuration to extend the battery life. 2Features: With temperature compensation employed to adjust charging parameters automatically. A wide range of load working modes facilitate the application to different types of load. 3Multiple Protections: With overcharge, over?discharge, overload protecting, as well as short?circuit protection. 12V/24V system voltages are automatically recognized. 4Large Load Starting: By virtue of an advanced load starting method, large?capacitance loads can be started smoothly. Boasting an industrial grade design, can function well in various tough conditions. 5Convenient to Use: Tvs lighting protection, a dot graphic Lcd screen and a human?machine interface with a key. The user?friendly browser and dynamic interfaces ensure convenient and intuitive operations.
