Features 1、3‑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. 2、Features: With temperature compensation employed to adjust charging parameters automatically. A wide range of load working modes facilitate the application to different types of load. 3、Multiple Protections: With overcharge, over‑discharge, overload protecting, as well as short‑circuit protection. 12V/24V system voltages are automatically recognized. 4、Large 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. 5、Convenient 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.
