10A 300W DC-DC Step-Down Adjustable Constant Voltage & Constant Current Module XL4016
[Step Down Buck Converter] 10A 300W DC-DC Step-Down Adjustable Constant Voltage & Constant Current Module XL4016 The 10A 300W DC-DC Step-Down Adjustable Constant Voltage & Constant Current Module is a high-power adjustable buck converter designed for applications requiring regulated output voltage and controlled output current. It can be used as a high-power LED driver, battery charging module, regulated power supply, and vehicle power supply. The module features independent CV (Constant Voltage) and CC (Constant Current) adjustment using onboard 3296 multi-turn potentiometers, allowing precise adjustment of the output voltage and current. A dual heatsink design helps dissipate heat from the power components during high-power operation. With a maximum advertised power rating of up to 300W, the module is suitable for high-power applications when adequate cooling and an appropriate input supply are provided. For continuous high-current operation, additional forced-air cooling is recommended. ⭐ Key Features Up to 300W output power 10A maximum output current Adjustable constant voltage and constant current CV and CC independent adjustment Output voltage continuously adjustable Typical output voltage range: 1.25V–35V High-power DC-DC step-down/buck converter Dual heatsink design for improved heat dissipation Independent heatsink for MOSFET/Schottky diode section 3296 multi-turn potentiometers for precise adjustment High-frequency capacitors for reduced output ripple Large Sendust core Double pure-copper winding Suitable for LED driver and battery charging applications Additional cooling recommended for continuous high-power operation 📋 Technical Specifications Product Type: DC-DC Step-Down Buck Converter Function: Constant Voltage / Constant Current Maximum Output Power: Up to 300W Maximum Output Current: 10A Recommended Continuous Current: Up to approximately 8A with additional cooling Output Voltage: Continuously adjustable, approximately 1.25V–35V Minimum Voltage Difference: Approximately 1V Adjustment: CV / CC Multi-Turn Potentiometers Potentiometer Type: 3296 Multi-Turn Operating Temperature: -40°C to +85°C Output Ripple: Approximately 50mV under the stated test conditions Cooling: Dual Heatsink Additional Cooling: Cooling fan recommended for continuous high-power operation Converter Type: Step-Down / Buck 🔧 Applications High-Power LED Driver Constant Current LED Power Supply Lithium Battery Charging Lead-Acid Battery Charging Ni-Cd / Ni-MH Battery Charging 6V Battery Charging 12V Battery Charging 14V Battery Charging 24V Battery Charging Solar Panel Power Systems Wind Generator Applications Vehicle-Mounted Power Supply Laptop Power Supply Regulated DC Power Supply Low-Voltage Power Supply Systems 🎛️ CV & CC Adjustment The module has two independent multi-turn adjustment potentiometers: CV (Constant Voltage): Adjusts the required output voltage. CC (Constant Current): Adjusts the maximum/constant output current. Turn the potentiometers clockwise to increase and anticlockwise to decrease the corresponding setting. Use a reliable multimeter while adjusting the output voltage and current. 🔋 Battery Charger Application Determine the required battery charging voltage and charging current. Connect a suitable DC input supply to the module while observing correct polarity. Use the CV adjustment to set the required charging voltage. Use the CC adjustment to set the required charging current. Connect the battery to the output while observing correct polarity. Monitor the charging process and ensure the voltage and current remain within the battery manufacturer's specifications. 💡 Constant Current LED Driver Application Determine the LED's required operating current and maximum operating voltage. Adjust the output voltage to a low safe level before connecting the LED. Use the CC adjustment to set the required LED current. Adjust the CV setting according to the LED's required operating voltage. Connect the LED and verify the output voltage and current with a multimeter. 🛠️ Adjustment Instructions If the output voltage initially follows the input voltage and cannot be adjusted, turn the appropriate potentiometer counterclockwise for multiple turns and then adjust again. Turn the adjustment potentiometers clockwise to increase and anticlockwise to decrease. Always use a multimeter when setting voltage or current. The potentiometer closest to the output side is specified for CC/current adjustment. The potentiometer closest to the input side is specified for CV/voltage adjustment. 📦 Package Includes 1 × 10A 300W DC-DC Step-Down Adjustable Constant Voltage & Constant Current Module ⚠️ Precautions This is a step-down (buck) converter; the input voltage must be higher than the required output voltage. Do not exceed the module's maximum voltage, current, or power limits. 300W is the maximum advertised power rating; actual continuous power depends on input voltage, output voltage, current, efficiency, and cooling. For continuous high-current operation, use a cooling fan with the heatsink. Do not short-circuit the output. Observe correct input and output polarity. Use appropriate protection when charging batteries. Never leave a battery charging unattended. Ensure the module's heatsink does not become excessively hot during operation.
