Features: 1. Constant output voltage/current, continuously adjustable. 2. High conversion efficiency up to 96%. 3. High power electronic components, stable and reliable. 4. Adopt aluminum substrate PCB with good thermal conductivity. 5. Mainly used for LED drive, DIY power supply, car power supply, solar charging power supply, battery charging, etc. Specification: Input Voltage: DC 10-40V Input Current: 6A Max Static Working Current: 10mA Output Voltage: DC 10-50V continuously adjustable Output Current: 6A Max (decreases as the voltage difference between input and output increases, please enhance heat dissipation when over 4A) Constant Current Range: 0.2-6A Output Power: Input voltage x 6A Working Frequency: 150kHz Conversion Efficiency: 92%-96% Input Reverse Connection Protection: Support Operating Temperature: -40~85 Module Size: 70*36*13mm / 2.7*1.4*5.1in Weight: Approx. 64g/2.2oz Output Voltage Regulation: Adjust the RV1 potentiometer and set the output voltage to your desired voltage according to your battery or LED. Output Current Regulation: Turn the RV2 potentiometer clockwise for about 30 turns to set the output current to the minimum value and connect it to the LED, adjust RV2 potentiometer to the required current. For charging the battery, connect the output after discharging the battery, then adjust the RV2 to the current you need. Package list: 1 * Step-Up Power Supply Note: 1. The input/output voltage and current must not exceed the maximum value during operation to avoid damage to the power supply. 2. Pay attention to ventilation and heat dissipation when working for a long time to extend the service life of the power supply.
