Setup and Assembly
This is a DIY solder kit that requires assembly. Follow the instructions carefully to ensure proper functionality. The kit is designed for beginners and enthusiasts interested in electronics.
- Component Identification: Before soldering, identify all components using the provided component list and the markings on the PCB.
- Soldering Order: It is generally recommended to solder smaller components (resistors, diodes) first, followed by larger components (capacitors, IC sockets, terminals). This prevents larger components from obstructing access to smaller pads.
- Polarity: Pay close attention to the polarity of components such as diodes, electrolytic capacitors, and integrated circuits (ICs). Incorrect polarity can damage the components or the entire module.
- Solder Joints: Ensure each solder joint is shiny, smooth, and forms a good connection without bridging to adjacent pads.
- Digital Display: Carefully solder the digital LED display module to its designated position.
- Input/Output Terminals: Solder the input and output terminals securely.
Image 2: Wiring Diagram. This diagram illustrates the input voltage connection (DC 15V-20V) and the various output terminals including 1.5V, 3.3V, 5.0V, 12V, and an adjustable output from 2.2V to Vin. The 1.5V socket provides a maximum current of 1A, while all other sockets can output a maximum current of 4A.
Operating Instructions
Once assembled, the power supply module is ready for operation. It features an adjustable output voltage and a digital display.
- Power Input: Connect a DC power source (15V-20V) to the input terminals (Vin and GND). The maximum input power is 36W.
- LED Indicator: A red LED indicator light will illuminate when the board is powered, confirming the module is receiving power.
- Output Voltages: The module provides fixed output voltages of 1.5V, 3.3V, 5V, and 12V.
- Adjustable Output: The integrated potentiometer allows you to adjust the output voltage on the ADJ terminal. Use a "+" screwdriver to turn the potentiometer and change the output voltage. The adjustable range is typically 2.2V to Vin (input voltage).
- Digital Display: The three-digit LED digital display shows the current output voltage, allowing for precise adjustment.
- Current Output: The 1.5V output socket provides a maximum current of 1A. All other output sockets (3.3V, 5V, 12V, and ADJ) can output a maximum current of 4A.

Maintenance
The PEMENOL Power Supply Module is designed for durability. Regular maintenance is minimal but important for longevity.
- Cleaning: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or solvents.
- Storage: Store the module in a dry, cool environment when not in use.
- Inspection: Periodically inspect solder joints and components for any signs of damage or loose connections. Re-solder if necessary.
Troubleshooting
Refer to the following points if you encounter issues with your power supply module:
- Output Voltage Lower Than Input: The module functions as a voltage reducer. The output voltage will always be lower than the input voltage, with a minimum voltage difference of 0.3V.
- Voltage Difference: The lower the input voltage, the greater the voltage difference between input and output, typically ranging from 0.1V to 0.3V.
- Dim/Off Display: If the input voltage drops below 4V, the brightness of the digital display will significantly decrease. It will turn off completely at 3.8V. Ensure adequate input voltage.
- ADJ Output Voltage Limits:
- If input voltage drops below 6.5V, the highest ADJ output voltage reaches 6.5V.
- If input voltage drops below 6.5V, the lowest ADJ output voltage is above 2.2V.
- If the input voltage is 15V, the ADJ output voltage range is 2.2V to 14.8V.
- If the input voltage exceeds 15.2V, the maximum ADJ output voltage is 15.2V.
- Dim Red Indicator Light: If the output voltage is below the normal expected value, the brightness of the red indicator light will be dim. Check connections and input voltage.
- Maximum Input Voltage: To prevent damage, the maximum recommended test input voltage is 20V. Do not exceed this limit.
