1. Adjust the CV-ADJ potentiometer to set the output voltage to the voltage you need based on your battery or LED. For example, set the voltage of a string of 10 LEDs to 37V. (Counterclockwise the voltage increases, clockwise the voltage decreases) 2. Turn potentiometer CC-ADJ counterclockwise about 30 turns, set the output current to 1, connect the LED and adjust potentiometer RV2 to the current you need. To charge the battery, once the battery is completely discharged, connect it to the output and adjust the RV2 to the current you need. The higher the charging current, the lower the charging current. ) (Counterclockwise current decreases, clockwise current increases.)Please do not adjust the current to short circuit. The circuit structure of the boost module cannot be adjusted in short circuit.Scope :1. Create a regulated power supply with 12V input and 12~50V adjustable output. 2. To power your electronic devices, you can set the output value based on your system voltage.3. As a car power supply, power your laptop, PDA or various digital products.4. Create a high-power mobile laptop power supply: Equipped with a large-capacity 12V lithium battery, your laptop can be illuminated wherever you go.5. The solar panel voltage is stable.6. Charge batteries, lithium batteries, etc. 7. Drive high power LED lights.Module Name 400W Boost Constant Current Module Module Specifications: Non-isolated boost module (BOOST) Input voltage: DC8.5V-50V. Input Current: 15A (MAX) is higher than 8A, please strengthen heat dissipation Quiescent operating current: 10mA (between 12V and 20V, the higher the output voltage, the higher the quiescent current) Output voltage: 10-60 V continuously adjustable Output current: 12A, maximum 7A, please strengthen heat dissipation (related to the input and output voltage difference, the higher the voltage difference, the smaller the output current).Constant current range: 0.2-12A Output Power: = input voltage * 10A, for example: 12V input * = 60W, 24V input * = 120W, 36V input * = 180W, 48V input * = 240W, Operating temperature: -40~+85 degrees (please strengthen heat dissipation when the ambient temperature is too high) Working frequency: 150 KHz Conversion efficiency: 96% (efficiency is related to input voltage, output voltage, current and voltage difference) Overcurrent protection: Yes (If the input exceeds 1, the output voltage will automatically decrease, with a certain error range.)Input reverse connection protection: None (if larger reverse connection current is required, please connect a diode in series with the input end) Installation method: 4 x 2.5mm screw holes. Wiring method: wiring output Module dimensions: 67 mm length, 48 mm width, 28 mm height Module unit weight: 60 grams
