Application:

1. Normal step down module

   1>. Adjust potentiometer "ADJ-V" to set output voltage;

   2>. Short ouput "+" and "-" and adjust potentiometre "ADJ-I" to set output current;

   3>. Connect load

2. Battery charger

   1>. Make sure battery's float voltage and charging current(if
lithium battery is 3.7V/2200mAh,so the float voltage is 4.2V and max
charging current is 1C ,);

   2>. Under no-load conditions and adjuset "ADJ-V" to set output voltage at float voltage;

   3>. Short ouput "+" and "-" and adjust potentiometre "ADJ-I" to set output current at charging current;

   4>. Connect battery.

3. Constant current LED driver module

   1>. Make sure LED working current and voltage;

   2>. Under no-load conditions and adjuset "ADJ-V" to set output voltage at LED working voltage;

   3>. Short ouput "+" and "-" and adjust potentiometre "ADJ-I" to set output current at working current;

   4>. Connect LED.
