400W DC-DC Step-up Boost Converter Constant Current Power Supply Module


Module properties: Non-isolated boost module (BOOST)
Input voltage: DC8.5V-50V
Input current: 15A (MAX) If it exceeds 8A, please increase heat dissipation
Quiet working current: 10mA (When the output voltage is increased from 12V to 20V, the higher the output voltage, the higher the static current will be)
Output voltage: 10-60V continuously adjustable (the default output is 19V. If you need other voltages, please inform the shopkeeper.)
12-80V fixed output
Output current: 12A MAX. If it exceeds 7A, please increase 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 * = 60W, input 24V * = 120W,
Input 36V*=180W, Input 48V*=240W,                 
Working temperature: -40~+85 degrees (please increase heat dissipation when the ambient temperature is too high)
Working frequency: 150KHz
Conversion efficiency: 96% (efficiency is related to input and output voltage, current and pressure difference)
Overcurrent protection: Yes (when the input exceeds 1, the output voltage will be automatically reduced, with a certain range of error.)
Input reverse protection: None, (If you need a higher reverse current, please connect a diode in series with the input)
Installation method: 4 2.5mm screw holes
Wiring method: Wiring output
Module size: Length 67mm, width 48mm, height 28mm
Module weight: 60g


Output voltage/current adjustment method:


1. Adjust the "CV-ADJ" potentiometer to set the output voltage to the voltage value you need according to your battery or LED. For example, adjust the voltage of 10 strings of LEDs to 37V. (Counter-clockwise voltage increases, clockwise voltage decreases)


2. Adjust the "CC-ADJ" potentiometer counterclockwise for about 30 turns to set the output current to , connect the LED, and adjust the RV2 potentiometer to the current you need. For battery charging, discharge the battery, connect it to the output, and adjust RV2 to the current you need. (When charging, you must use a fully discharged battery to adjust it accurately, because the more power the battery has, the smaller the charging current.) (Counterclockwise current is adjusted to a smaller value, and clockwise current is adjusted to a larger value)


Please do not use short circuit to adjust the current. The circuit structure of the boost module cannot be adjusted by short circuit.
