DC-DC Adjustable Step Down Converter Module 5A Regulated Power Supply

Features: Step-down voltage module with over-current protection; suitable for use as a charger for various batteries, solar panels, and wind turbines; can also be used as a high-power LED constant current driver. Indicator shows CC/CV mode and charging status (charging or fully charged). Input voltage: DC 4V–38V; output voltage: DC 1.25V–36V continuously adjustable; maximum output current: 5A; maximum output power: 75W. Includes short-circuit and over-temperature protection. Features constant current (CC) and constant voltage (CV) modes; float voltage and charging current can be set when used as a lithium battery charger; up to 96% efficiency; low ripple. Specifications: Module type: Non-isolated Buck Module Input voltage: 4–38V (do not exceed 38V) Output voltage: 1.25–36V continuously adjustable Output current: 0–5A, recommended for use within 4A Output power: Recommended for use within 75W; for loads above 50W, a heatsink is recommended Operating temperature: -40°C to +85°C Switching frequency: 180kHz Conversion efficiency: Up to 96% (efficiency varies based on input/output voltage, current, and voltage difference) Load regulation: ≤0.8% Voltage regulation: ≤0.8% Power indicator: Yes Short-circuit protection: Yes (current limited to 8A) Over-temperature protection: Yes (automatically disables output when overheated) Reverse polarity protection: None (if required, add a high-current diode in series at input) Mounting method: 2 x 3mm screw holes Wiring method: Soldering required; V-IN is input, V-OUT is output Note: Due to lighting and shooting angles, slight color variations may occur. Allow 0–3mm measurement deviation due to manual measurement. Package includes: 1 x Step-Down Power Supply Module
