Describe: 1. High conversion efficiency, power saving, and low working temperature. The components are selected from temperature resistance above 105 C. After the battery is full, it will be automatically stopped and transferred to the floating charging state. At this time, the charging has a repair effect on the battery. Therefore, the battery will not cause the battery to reduce the capacity and shorten the service life due to overloading or insufficient charging. Overcoming the shortcomings of old -fashioned low -frequency chargers, it increases the discharge capacity and service life of the battery. 2. There is a soft startup function, the starting current is small, and the AC input impact is effectively reduced. Can withstand frequent switches start, and will not cause damage to the power. 3.
