How to operation
Voltage adjustment
When the power supply is unloaded, use a flat-blade screwdriver to adjust the output terminal "V-ADJ" potentiometer (marked in the figure below) to increase clockwise and counterclockwise to adjust). Because the output capacitor capacity is large, the output voltage is When the high voltage is adjusted to a low voltage, the reaction will be slower. The adjustment of the instrument is smaller.
Current adjustment
Adjust the "CC A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the load such as the LED battery, and adjust the "CC A-ADJ" potentiometer clockwise to the current you need. For battery charging, ensure that the capacity of the battery does not exceed the capacity of this module. Connected discharged battery to the output, and adjust the CC A-ADJ to the current you need while measuring with current meter. Do not use the short-circuit output to adjust the current, the circuit structure of the boost module can not be adjusted by short circuit.
