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 enhances solar charging efficiency. Output error indicator light illuminates when output voltage drift, short circuit, or other faults occur. Oxidized heat sink provides effective heat dissipation compared to natural aluminum sheets. Inductor uses 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: Up to 10A (MAX), suitable for long-term use within 7A Output power: Suitable for long-term use up to 80W; for 130W operation, enhanced heat dissipation is required Output ripple: 50mV (measured at 12V to 12V) Input reverse connection protection: Not included; if needed, connect a Schottky diode in series at the input Output backflow protection: Not included; for battery charging or self-loading applications, connect a Schottky diode in series at the output Dimensions: 77.6 x 46.5 x 15mm Short circuit protection: Yes Product appearance and printed markings may vary by batch, but this does not affect functionality.
