  2. Input -
  3. Constant Current Indicator
  4. Constant Current Regulation
  5. Output +
  6. Output -
  7. Output Indicator
  8. Output Voltage Regulation


To use the module, connect it to the power supply to initiate voltage output. Connect the output terminal to a multimeter for voltage measurement, and adjust the output voltage using the voltage adjustment potentiometer. For constant current adjustment, set the multimeter to the 10A current gear, connect probes to the output, and adjust the constant current potentiometer. The displayed current on the multimeter reflects the constant current value. After these adjustments, connect the module to the load for proper functionality.

Note: When dealing with high power, consider adding heat dissipation if significant heating issues arise.
