  • CV Potentiometer: Adjusts output voltage. Turn clockwise to increase voltage and counterclockwise to decrease voltage.
  • CC Potentiometer: Adjusts maximum output current. Turn clockwise to increase the current limit, and counterclockwise to decrease it.

Applications:

  • Lithium-ion battery charging systems
  • Lead-acid battery chargers
  • High-power LED drivers
  • Laboratory bench power supplies
  • Solar power systems
  • DIY electronics projects
  • Industrial automation equipment
  • Motor and controller power regulation

Important Notes:

  • No Reverse Polarity Protection: Reversing the input polarity may permanently damage the module.
  • Input voltage must always be higher than the desired output voltage.
  • For continuous loads above 5A–6A, active cooling with a fan is strongly recommended.
  • The module can reach its maximum 300W rating only under suitable voltage, current, and cooling conditions.
  • Monitor heatsink temperature during high-power operation to prevent overheating.

How to Use:

  1. Connect the DC input source to the IN+ and IN- terminals.
  2. Connect the load or battery to the OUT+ and OUT- terminals.
  3. Adjust the CV potentiometer to set the desired output voltage.
  4. Adjust the CC potentiometer to set the desired current limit.
  5. Verify voltage and current settings using a multimeter before connecting sensitive loads.
  6. Install additional cooling if operating at high current levels for extended periods.
