1.12V/ 24 V system voltages are automatically recognized.
2.An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charging to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery's service life.

3.With temperature compensation employed, charging parameters can be automatically adjusted.
4.A wide range of load working modes facilitate the product's application to different types of load.
5.The product provides overcharge, over-discharge, overload protection, as well as short-circuit protection.
6.By virtue of an advanced load starting method, large-capacitance loads can be started smoothly.
7.The product provides a dot matrix graphic LCD screen and a human-machine interface with a key.
8.The user-friendly design of browser and dynamic interfaces ensure convenient and intuitive operations.
9.Boasting an industrial grade design, the product can function well in various tough conditions.

10.TVS lighting protection is adopted.
