Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.\u003cbr\u003e 2. Set the CC potentiometer approximately 30 turns counterclockwise (i.e., set the output current to the minimum), connect the LED, and adjust the CC potentiometer to the required current.\u003cbr\u003e To recharge the battery after it is completely discharged, connect it to the output and adjust the CC to the required current. (The higher the setting, the lower the charging current.)\u003cbr\u003e\u003cbr\u003e Special features:\u003cbr\u003e Condition: 100% brand new\u003cbr\u003e Input voltage: DC6-40V\u003cbr\u003e Output voltage: Continuously adjustable (1.2-35 VDC) for extended periods below 32 V (suitable for applications where the input voltage is higher than the output voltage and cannot be amplified)\u003cbr\u003e Output current: Maximum 20 A within 15 A for extended periods (please add a fan for heat dissipation if the power tube temperature exceeds 65 degrees, and use a power reduction for the high-voltage output)\u003cbr\u003e Current limiting range: 0.2-20 A (setting).
