Application:
The DC/DC buck module applications the input voltage is higher than the output voltage of the buck field, such as battery, power transformer, DIY adjustable regulated power supply, 24V Vehicle notebook power supply, industrial equipment buck.12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, buck to 24V etc.
Note:
If you found that the output voltage of the module cannot be adjusted and it’s always equal to the input voltage, please turn the potentiometer counterclockwise for more than 10 turns and use the module to adjust the voltage normally.
The original output voltage is around 20V.
