Application:
DIY mobile power, monitor power supply, power buggies, camera power supply, car power, communications equipment supply,etc.
You can adjust the voltage by placing a multi-meter on the output, synchronously, using a screw driver to adjust a potentiometer.
It can be minute adjustments to achieve a precise voltage.

Package Included:
15 x DC to DC buck converter board

Note:
These boards are adjustable current limiting, fixed 3A current limit.
Please make sure that this module within its working range before using.
Please don't output short circuit, otherwise the board would burn out.
When setting the parameter, please make sure output voltage is stable before using the module to avoid any possible damage.
The input voltage should not be over 28 V to avoid damage15
