20W Adjustable DC-DC Boost Converter With Digital Display

This 20W adjustable DC-DC boost converter with a digital display supports 3~32V power input, 5~35V output the conversion efficiency can reach 94%, it has the functions of overheating protection and short-circuit protection, and the performance is very powerful.

The module is equipped with terminals, which can be easily used without iron, and retains the welding wire connection points. The two methods of use are very convenient. It can be used in boosting fields where the input voltage is lower than the output voltage.

The on-board voltmeter supports self-calibration mode. You can get accurate voltage values on the entire voltage range with only one calibration.

This is a multipurpose boost converter. Supply voltage is as low as 5VDC and it boosts to as high as 35V.
