4.Set the voltage and current method
1, set the output voltage: according to the battery you want to charge the float voltage, or string, parallel to the LED voltage, adjust the constant voltage potentiometer (CV), the output voltage is set to the required voltage. (Without load)
2, set a constant current value: the first CC potentiometer counterclockwise 20 laps or so, with a multimeter 20A current file short-circuit output, adjust the CC potentiometer to you need to set the current value.
Note: constant current set when the voltage is higher than 1.2V, otherwise the constant current function will be invalid.

pay attention
1. Please use this product, the module input and output are not together, this will cause the module's current sampling resistor is bypassed, so that the module can not adjust the output current size, then the case of large load easily Burn the module.
2. A customer reflects the module output voltage can not be adjusted, when you encounter this problem, please counterclockwise rotation of the CV potentiometer more than 20 laps, and then use the module can be normal adjustment of the voltage. Because the module factory, the default output voltage of about 18V. We are not responsible for the return of such questions and freight, thank you for your understanding.

Voltage and current adjustment method: (using a tool multimeter and a flat screwdriver)
Voltage regulation: turn the blue Potentiometer on the power panel according to the voltage you need, and turn the voltage up clockwise and down counterclockwise;
Output current regulation: turn the multimeter or Ammeter to 20A or 10A current gear, adjust the power supply voltage to 5V, turn the constant current Potentiometer counterclockwise for about 10 turns, adjust the current to the minimum, use the multimeter for short circuit output, and then adjust the Potentiometer clockwise to adjust the current to the required current value;
The current detection of the module is a low-end detection. Please do not directly short circuit the input negative pole and output negative pole with wires, as the short circuit negative pole power supply may not have constant current, resulting in damage to the power supply and electrical equipment that requires constant current.
The module is a step-down power supply that can only reduce voltage but cannot increase it. The input voltage must be higher than the output voltage.
