(1) Adopt switching power supply structure, wide input AC voltage range, small size, light weight and high efficiency(2) The two-stage charging method (constant current first and then constant voltage mode) is used for automatic charging, and the charging is fully carried out according to the charging characteristics of the battery. Prevents lead-acid batteries from overcharging and maximizes battery life(3) Built-in PFC circuit, the highest power factor can be calibrated to above 0.99(4) Built-in current protection circuit, which can effectively protect the charger in case of overcurrent, short circuit and reverse connection, and quickly use the power indicator and charging indicator flashing as an alarm(5) External LED status display: green power light indication; red charging light indicationcolor:BlackMaterial:MetalPackage Contents:1 x Generator Charge Control BoxOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
