Step Down Converter Module DIY Power Voltage Regulator Adjustable Power Supply Module, 12 Pcs LM2596 Buck Converter

ALMOCN - The input and output interface can not be reversed. The efficiency of the lm2596 up to 92%, power loss=amount of heating=100%-efficiency %, the heating power will be about 8% of the input power, much less than a resistive voltage dropper.

The buck converter consists of 36u thickened circuit boards, high-Q inductance with output indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. This is an adjustable module. The input voltage must be higher than the output voltage. The input and output interface can not be reversed. Keep it under 2. 5 a and use the heat sink when working for long hours.

These voltage converters can be used for camera, 3D printer, computer fans replacement, prototyping project, battery charging systems, and other devices powered by solar panel system. Connect to power source, adjust the swirl button on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to voltage.
