4. การติดตั้งและการเดินสายไฟ

Follow these steps for proper setup and wiring of the boost converter:

1. Initial Undervoltage Protection (UVP) Adjustment: Before connecting any load, adjust the UVP potentiometer (labeled 'UVP' on the board) to its minimum setting. This prevents premature shutdown during initial setup.
2. ปริมาณการส่งออกtage การตั้งค่า: Connect the input power (DC 14-85V) to the VIN+ and VIN- terminals. Then, adjust the CV (Constant Voltage) potentiometer (labeled 'CV' or 'Output Voltage Adjustment') to set the desired output voltage. บันทึก: ปริมาณการส่งออกtagค่า e จะต้องสูงกว่าค่า vol ที่ป้อนเข้ามาเสมอtage for boost operation. For 120V output, the input voltage ต้องมากกว่า 20V
3. Constant Current (CC) Setting (for Constant Current Loads): If you are using a constant current load (e.g., an LED lamp or battery charging), first adjust the CC (Constant Current) potentiometer (labeled 'CC' or 'Output Current Regulation') to its minimum setting. Then, connect your load. Gradually increase the CC potentiometer until the desired output current is reached. สำคัญ: ปริมาณโหลดtage ต้องสูงกว่าปริมาตรอินพุตtage for the boost power supply to operate correctly. For example, a 12V input can only charge 24V or higher batteries; a 24V input can only charge 36V or higher batteries.
4. ลำดับการเปิดเครื่อง: After setting both voltage and current, first turn on the boost power supply, then connect the load.

5. Operating Notes and Performance Considerations

• เล่มที่tage Extremes: Avoid operating the converter at the absolute highest or lowest input and output voltage limits simultaneously for prolonged periods.
• Operating Current Calculation: The operating current must not exceed the maximum input current of 20A. Calculate the operating current using the formula:
  Operating Current = (Output Voltage * Output Current) / (Input Voltagอี * 0.94)
  (Where 0.94 represents an approximate efficiency of 94% for calculation purposes, as 1.06 is the loss factor).
  Exampเลอ: For a 1200W model, if input is 15V, output is 48V, and load current is 5A: (48V * 5A) / (15V * 0.94) = 240W / 14.1V ≈ 17.02A. This is below 20A, so it can operate normally. If the load is 48V 7A: (48V * 7A) / (15V * 0.94) = 336W / 14.1V ≈ 23.83A. This exceeds the 20A input limit, so it cannot be used.
• ประสิทธิภาพ: Efficiency is highest when the difference between input and output voltage is small. A larger voltage difference results in lower efficiency. For instance, with a 20V input and 120V output, efficiency will be at its lowest, potentially below 90%. Ensure the input power source can supply at least 1.5 times the required load power.
• การปรับปัจจุบัน: It is strictly forbidden to adjust the output current by short-circuiting the output terminals. This can damage the module.
• Supercapacitors: Charging supercapacitors is strictly forbidden.
• การทำงานของพัดลม: The cooling fan is temperature-controlled and will only activate when the heatsink temperature reaches approximately 40°C. It is normal for the fan to be off at lower temperatures.
• Power Output Limitations: The advertised 1200W output is theoretical. Due to the 20A input current limit, the actual maximum output power depends on the input voltagเช่นample, with a 14V input, the maximum input power is 14V * 20A = 280W. After conversion losses, the practical maximum output power will be around 250W. It is recommended not to exceed 210W output when the input is 14V to ensure stable operation and longevity. To achieve higher output power, a higher input voltage (e.g., above 64V for maximum output) is required.

8 การแก้ไขปัญหา

• ไม่มีเอาท์พุทVoltage: Verify input power is within 14-85V. Ensure the output voltage setting is higher than the input voltage. Check for correct wiring.
• Output Current Cannot Be Adjusted: Ensure you are not attempting to adjust current by short-circuiting the output. Adjust the CC potentiometer with a proper load connected.
• พัดลมไม่ทำงาน: The fan is temperature-controlled and will only activate when the heatsink reaches approximately 40°C. If the module is cool, the fan will not run. If the module is hot and the fan is still not running, check fan connections.
• Lower Than Expected Output Power: Review the operating current calculation in Section 5. Ensure your input voltage is sufficient for the desired output power, considering the 20A input current limit and efficiency losses. Increase input voltage if possible, or reduce load.
• โมดูลร้อนเกินไป: Ensure adequate ventilation around the module. Check if the load exceeds the module's capabilities for the given input voltage.
