Fuction:
1.Built in over-temperature protection function
2.Built in current limit function
3.Built in output short-circuit protection function

How to use
1.Access the power supply ( 3 -40 V), the power indicator light, the module is working properly.
2.Adjust the blue potentiometer knob (usually clockwise rotation boost, counterclockwise rotation Step-down) and monitor the output voltage with a multimeter to reach the required voltage.
3.A customer reflects the module output voltage can not be adjusted, always equal to the input voltage. When you encounter this problem, please first counterclockwise rotation potentiometer 10 laps above, and then use the module can be normal adjustment of the voltage.
