The input uses a replaceable fuse to protect the power supply and equipment. The entire electrolytic board features patch components, low resistance, and high-frequency capacitors to minimize ripple voltage. Provides constant voltage, constant current, and undervoltage protection. MPPT technology is optimized for solar charging applications. Output error indicator light illuminates when output voltage drift, short circuit, or other faults occur. Oxidized heat sink provides efficient heat dissipation compared to natural aluminum. Inductor uses iron silicon aluminum material, generating less heat during operation.
