1,The shortest way to convert high current, reduce current loss and further improve the conversion efficiency. 2,Adopt centralized double air duct left and right uniform heat dissipation, reduce MOS tube temperature, improve conversion efficiency, from the previous single air duct multiple groups of in series innovation to single transformer vertical multi-layer copper ring superposition winding method, reduce copper loss magnetic loss, reduce heat, improve efficiency. Working efficiency from 80% to 90%. 3,Double current detection of the front and rear stages, multiple protection, to achieve efficient and stable operation of the inverter, will not cause damage to the power supply equipment and load equipment due to damage to a single electronic component. 1: Aluminum alloy shell, light weight, good thermal conductivity, can quickly reduce the temperature of components, long-term work is not affected. 2: Pure sine wave, intelligent filtering, no interference with electrical appliances and protection of electrical appliances. High conversion efficiency (up to 90%), the low power consumption of the product itself can greatly extend the battery life.
