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. Constant voltage, constant current, and undervoltage protection functions are included. MPPT technology is optimized for solar charging applications. Output error indicator light illuminates when output voltage drift, short circuit, or other faults occur. The oxidized heat sink provides efficient heat dissipation compared to natural aluminum. The inductor is made of iron silicon aluminum material, generating less heat during operation. Electrical specifications: Input voltage: DC 5-32V, recommended above 10V Output voltage: DC 1-30V continuously adjustable Output current: 10A maximum, up to 7A for continuous use Output power: Up to 80W continuous; 130W with enhanced heat dissipation Output ripple: 50mV (measured at 12V to 12V) Input reverse connection protection: Not included. For protection, connect a Schottky diode in series at the input. Output backflow protection: Not included. When used for battery charging or with self-loading devices, connect a Schottky diode in series at the output.
