Feature

Input voltage rangeDC 3 -40 V (input voltage must be 1.5 V higher than the output voltage, no boost)
Output voltage rangeOutput: DC 1.5 - 35 V voltage is continuously adjustable, maximum output current is 3 A
With over-temperature and short-circuit protection, hence it is safe to use.
Easy to make it work and convenient to accurately adjust the output voltage with a mini screwdriver.
100% SATISFICATION SERVICE: If there are any problem with our products, please feel free to contact us. you can request a refund for any single module and no need to return it.; Any problems you can contact us and we will try our best to resolve it till you satisfied.NoteThe factory have tested these at max voltage so they are very high by default, takes about 15-20 turns CCW before the voltage starts ramping down)

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.

Package includes:
8X LM2596 board
8 pieces of heat sink
