Usage Instructions

1. Input Connection:

• Connect the DC power source to the input terminals (IN+ and IN-). Ensure correct polarity: the positive terminal goes to IN+ and the negative terminal to IN-.

2. Output Connection:

• Connect the load to the output terminals (OUT+ and OUT-). Ensure correct polarity: the positive terminal goes to OUT+ and the negative terminal to OUT-.

3. Adjusting Output Voltage:

• Use a multimeter to measure the output voltage.
• Adjust the output voltage by turning the small potentiometer on the module. Turn clockwise to increase the voltage and counterclockwise to decrease it.
• Ensure that the output voltage does not exceed the voltage rating of your load to prevent damage.

4. Powering On:

• Once all connections are secure and adjustments are made, power on the input power supply.
• Check the output voltage and current to ensure they are within the desired range.

5. Load Connection:

• Connect your load to the output terminals. The module should provide a stable, regulated voltage as per your adjustments.

6. Thermal Management:

• Ensure adequate ventilation around the module, especially when operating near the maximum power output.
• If the module gets too hot, consider adding a heat sink or improving airflow around the module.
