KEHIPI 200373 DC Buck Converter
This adjustable step-down module converts an 8V to 22V input into a 1V to 15V output with a maximum current of 3A. It is designed for electronics hobbyists and installers who need a compact, waterproof voltage regulator for projects such as car audio, LED displays or radio equipment. The sealed enclosure acts as a heat sink and provides industrial-grade durability against shock, humidity and dust. Two units are supplied in the package.
Thermals noise and power draw
The converter delivers up to 96% efficiency with a static consumption of about 12mA and output ripple around 100mV at 12V to 5V conversion. For continuous operation at 2A no extra heat dissipation is required, while the fully sealed metal case handles thermal load at the 3A peak. Operating temperature spans -20°C to +60°C for industrial use with a survival range down to -40°C and up to 80°C. Built-in protections cover reverse connection, over-current, over-voltage and over-heating.
Upgrade path and fit
This module replaces larger, non-sealed buck boards when a project demands waterproofing, vibration resistance or a tighter 33 x 25 x 20mm footprint. The bottom-mounted potentiometer prevents accidental adjustment once the unit is installed, a benefit over top-adjust designs. The jump is worthwhile when the installation faces moisture, dust or mechanical shock and the load stays within the 3A peak or 2A continuous ratings.

Questions about this item
How do I wire the three leads — red, yellow and black — and which step is often missed?
Connect red to input positive, yellow to output positive and black to the shared negative; the step often missed is confirming the input is at least 3 V higher than the desired output before powering up.
What ongoing care does the sealed module need and when might it need replacement?
The epoxy-sealed unit has no user-serviceable parts; if the over-temperature or over-current protection trips repeatedly under normal 2 A loads, the module should be replaced.
At what point does thermal protection become the limiting factor during continuous operation?
Sustained loads above 2 A at high input-output differentials will trigger the over-heating protection first, since the enclosure acts as the only heat sink.
