Buck Converter 3A
This buck converter or more commonly known as a stepdown module, has the incredible ability to step voltages of up to 22V - 120V down to 8V - 28V, which makes it unique, due to its high voltage input range and its ability to step this high voltage down to lower usable voltage without the need of a second buck converter. This is ideal if you have a 48V or higher voltage battery that you want to use to power a microprocessor such as an Arduino, or to power 12V LED lights. Due to the trim pot on the module, you can accurately adjust the output voltage to match your requirements.
