Waterproof Buck Converter 8-22V Input
The KEHIPI 090010 is a synchronous rectification step-down module that accepts a DC input between 8 V and 22 V and delivers an adjustable 3 V to 15 V output at up to 3 A. Its fully sealed enclosure doubles as a heat sink and meets CE, RoHS and UL specifications, making it suitable for harsh automotive or outdoor environments. The unit includes reverse-connection, over-current, over-heating and over-voltage protection for safe operation. A bottom-mounted potentiometer allows precise voltage trimming without accidental shifts once installed.
Hobbyists needing regulated low-voltage power
Builders powering radios, car audio amplifiers, LED displays, small motors or phone chargers from a higher-voltage vehicle or battery source will find the adjustable range and rugged sealing convenient. Users who require an input below 8 V or an output above 15 V cannot use this module. Projects demanding more than 3 A continuous current or a non-isolated topology with different protection features should look at alternative regulators.
Simple screw-terminal wiring with sealed housing
Installation consists of connecting the DC supply to the input terminals and the load to the output terminals, then adjusting the output voltage via the recessed potentiometer using a small screwdriver. The potted enclosure prevents moisture ingress but also means internal components are not serviceable. Ensure the input voltage remains at least 3 V higher than the desired output to maintain regulation, and verify polarity before powering up to avoid triggering the protection circuits.

Questions about this item
What minimum input voltage is required to get a 12V output from this 8-22V buck converter?
The input must be at least 3V higher than the output, so a 12V setting needs 15V or more at the input terminals.
Will the 3A current rating support a load that previously drew 2A from a 12V linear regulator?
Yes, the converter is rated for 3A continuous output, providing headroom above a 2A load at the same voltage.
How can I verify the output voltage is set correctly after wiring the module?
Measure the output with a multimeter before connecting the load; the potentiometer on the bottom adjusts the voltage between 3V and 15V.
