Module size: Length 70mm width 36mm height 13mm
Single module: 50 g
Output voltage / current adjustment method:
1, adjust RV1 potentiometer, according to your battery or LED, the output voltage is set to your desired voltage value. such as 10 LED string voltage regulator to 37V.
2, adjust RV2 potentiometer clockwise 30 laps, the output current is set to a minimum, connected LED, adjust RV2 potentiometer to the desired current. For battery charging, before connect to output,the battery must be fully discharged, then adjust RV2 to set the current. Please do not adjust the current short-circuited manner, the circuit structure of the booster module can not be short-circuited by way of transfer.
