Constant voltage, constant current, undervoltage protection (MPPT is more suitable for solar charging)Output error indicator light, which lights up when the output voltage drift is too serious, short circuit and other faults The whole electrolytic board adopts patch, low resistance, high frequency capacitor, so that the ripple is reduced to the freezing point The input adopts replaceable fuse to protect the power supply and equipment The heat dissipation effect of the oxidized heat sink is that of the natural aluminum sheet The inductor adopts iron silicon aluminum, which generates less heat, Manufacturer: Akfldms
