DC - DC 400W แปลงไฟจาก 8.5-40V เป็น 10-50V constant current boost module converter adjustable power transformer
*****(โปรดอ่านก่อน ก่อนใช้งานทดสอบป้อนอินพุท ที่ 10Vdc วัดเอาท์พุทจะได้ 15-17Vdc ซึ่งร้านทดสอบและปรับใว้แล้ว หากลูกค้านำไปต่อกับอินพุทที่สูงกว่านี้เช่น 20v จะต้องปรับตัวต้านทาน Rv1 ทวนเข็ม 10-15 รอบ เอาท์พุทถึงจะขึ้นตาม ไม่เช่นนั้นเอาท์พุทจะได้ 20v หากต่อกับอุปกรณ์อื่นที่ไม่ใช่ไฟDCที่แปลงจากไฟบ้าน อาจจะมีปัญหา มีปัญหาถ่ายคลิปและรูปส่ง ไฟเข้าเท่าไร ออกเท่าไร ก่อนทุกครั้งภายใน 7 วัน)*****
DC-DC adjustable boost constant current power module 400W 15A car charging transformer boost module board
Applications:
1. DIY power supply, 12V input and output adjustable 12-50V.

3. As a car power supply for your laptop, PDA or various digital products.
4. DIY mobile phone notebook power supply: 12V plus large capacity lithium battery.
5. Solar panel regulator.
6. Rechargeable lithium battery.
7. Drive high power LED lights.
product features:
- Module name: 400W boost constant current module
- Module Features: Non-Isolated Boost Module (BOOST)
- Input voltage: DC8.5V-40V
- Input current: 15A (MAX) exceeds 8A, please strengthen heat dissipation
- Static current: 10mA (12V 20V, the higher the output voltage, the higher the current, the greater the silence)
- Output voltage: 10-50V continuously adjustable (default output is 19V.)
- Output current: 12A (MAX) exceeds 7A, please strengthen heat dissipation (related to the input and output voltage difference, the larger the voltage difference, the smaller the output current.)
- Constant current range: 0.2-12A
- [Output power]: = input voltage * 10A, such as: input 12V * 5A = 60W, input 24V * 5A = 120W, input 36V * 5A = 180W, input 48V * 5A = 240W
-
- [Working temperature]: -40 ~ + 85 degrees (please strengthen heat dissipation when the ambient temperature is too high)
- [Working frequency]: 150KHz
- [Conversion efficiency]: up to 96% (efficiency is related to input, output voltage, current, and pressure difference)
- [Overcurrent protection]: Yes (If the input exceeds 15A, the output voltage is automatically reduced, and there is a certain range of error.)
- [Input reverse connection protection]: None, (if more reverse connection current is required, please input a diode in the input)
- [Installation]: 4 2.5mm screw holes
- [Wiring mode]: wiring output
- Module size: 67mm * 48mm * 28mm (LxWxH)
- Module weight: 60g
Output voltage / current adjustment method:
1. Adjust the "CV-ADJ" potentiometer and set the output voltage to the voltage you need according to your battery or LED. Such as 10 string LED voltage regulation 37V. (The counterclock voltage is increased, and the clockwise voltage is decreased.)
2. Adjust the "CC-ADJ" potentiometer counterclockwise about 30 turns, set the output current to the minimum, connect the LED, and adjust the RV2 potentiometer to the current you need. For battery charging, after the battery is discharged, connect it to the output and adjust RV2 to the current you need. (Be sure to use the discharged battery to adjust it when charging, because the remaining battery capacity is More, the smaller the charging current.) (Turn down the counter-clock current, increase the clock-clock current)
Please do not adjust the current by short circuit. The circuit structure of the boost module cannot be adjusted by short circuit.
