3. Enstriksyon Asanble

The assembly process involves soldering various electronic components onto the provided Printed Circuit Board (PCB). The kit includes a majority of through-hole components, along with a few surface-mount components (SMCs). Refer to the included paper manual for detailed, color-printed soldering steps and component placement diagrams.

General Soldering Guidelines:

1. Preparasyon: Ensure your soldering iron is clean and properly tinned. Work in a well-ventilated area.
2. Idantifye konpozan yo: Carefully identify each component using the provided paper manual and the markings on the PCB. Pay attention to polarity for diodes, LEDs, and electrolytic capacitors.
3. Surface-Mount Components (SMCs): If you are new to SMC soldering, it is recommended to watch instructional videos. For this kit, SMCs can typically be mounted using flux, solder, and a heat gun. Apply a small amount of solder to one pad, place the SMC, then heat the pad to melt the solder and position the component. Solder the remaining pads.
4. Through-Hole Components: Insert components into their designated holes on the PCB. Bend the leads slightly to hold them in place. Solder each lead from the underside of the board, ensuring a good, shiny solder joint. Trim excess leads after soldering.
5. Order of Assembly: Generally, it is best to solder smaller, lower-profile components first (e.g., resistors, diodes), followed by larger components (e.g., capacitors, ICs, terminal blocks, display module, power switch).
6. Enspekte jwenti yo: After soldering, visually inspect all solder joints for bridges, cold joints, or insufficient solder. Re-solder any problematic connections.

4. Enstalasyon

Once the module is fully assembled and all solder joints have been inspected, you can proceed with setting it up for operation.

1. Koneksyon pouvwa Antre: Locate the 'Input DC' terminal block on the PCB. Connect a DC power source (12V-20V) to these terminals. Ensure correct polarity: positive (+) to 'Vin' and negative (-) to 'GND'.
2. Pouvwa sou: Flip the power switch to the 'ON' position. The digital display should illuminate, showing the current voltage of the adjustable output, and the LED indicators for the fixed outputs should light up if a load is connected.

5. Operasyon

The BANRIA Power Supply Module offers multiple output voltages for various electronic projects.

Tèminal Sòti:

• Sòti fiks: The module provides four fixed voltage outputs: 1.5V, 3.3V, 5.0V, and 12V. Each has a dedicated terminal block. The +1.5V terminal outputs a maximum current of 1A, while all other terminals can output a maximum current of 4A.
• Adjustable Output (ADJ): The fifth output is adjustable. Use the blue potentiometer (trimmer) on the board to set the desired voltage. The digital display will show the current voltage of this output. The adjustable range is approximately 2.2V to Vin (input voltage), with a maximum output of 15.2V when input exceeds 15.2V.

Karakteristik kle:

• Pouvwa switch: A dedicated power switch allows for easy on/off control without repeatedly connecting/disconnecting the input power.
• Sòti Voltage Display: The digital display clearly shows the voltage of the adjustable output. The maximum display error is not greater than 0.45V.
• Endikatè ki ap dirije: Each fixed output has an LED indicator to show activity.

Voltage Characteristics:

• Voltage reduction function: Output voltage is lower than input voltage, with a minimum voltage difference of 0.3V.
• The lower the input voltage, the greater the voltage difference, ranging from 0.1V to 0.3V.
• Lè D' a voltage is below 4V, the brightness of the digital tube display significantly decreases; it completely turns off at 3.8V.
• Lè D' a voltage is below 6.5V, the highest voltage of ADJ reaches 6.5V.
• Lè D' a voltage is below 6.5V, the lowest voltage of ADJ is above 2.2V.
• Lè D' a voltage equals 15V, the ADJ output range is: 2.2V to 14.8V.
• Lè D' a voltage exceeds 15.2V, the maximum voltage output by ADJ is 15.2V.
• Lè pwodiksyon an voltage is below the normal value, the brightness of the red indicator light will become dim.

6. Antretyen

To ensure the longevity and reliable operation of your power supply module, follow these maintenance guidelines:

• Keep the module clean and free from dust and debris. Use a soft, dry brush or compressed air for cleaning.
• Evite ekspoze modil la a imidite oswa tanperati ekstrèm.
• Periodically check solder joints for any signs of cracking or corrosion, especially if the module is frequently moved or subjected to vibrations.
• Ensure proper ventilation around the module during operation to prevent overheating.

NAN. Depanaj

If you encounter issues with your BANRIA Power Supply Module, consider the following troubleshooting steps:

• Pa gen kouran/Ekspozisyon etenn:
  • Check the input power source (12V-20V DC) and its connections to the module.
  • Asire w ke switch pouvwa a nan pozisyon 'ON'.
  • Verify all power-related solder joints (input terminals, power switch, display module) are solid.
  • Si opinyon voltage is below 3.8V, the display will be off.
• Volim Sòti ki Pa Kòrèktage:
  • For fixed outputs, check the corresponding LM2596T IC and its surrounding components for proper soldering.
  • For the adjustable output, ensure the potentiometer is correctly installed and functioning. Rotate it to see if the voltage chanjman.
  • Verifye opinyon voltage se nan seri a espesifye (12V-20V).
• No Output/Dim LED:
  • Check the solder joints for the specific output terminal and its associated components.
  • Ensure no short circuits are present on the output.
  • A dim red indicator light may suggest the output voltage is below its normal value.
• Surchof Konpozan:
  • Ensure no short circuits are present on the outputs or input.
  • Verify that the load connected to the output does not exceed the maximum current rating (1A for 1.5V, 4A for others).
