GCON 2pcs Waterproof DC Buck Converter 8V-22V to 3V-15V 3A gender changer
Waterproof step-down module converts 8–22 V input to an adjustable 3–15 V output at up to 3 A with built-in protection
- Adjustable 3 V–15 V output from 8 V–22 V input
- 3 A peak current with 2 A continuous rating
- Four protection circuits prevent damage from faults
- Waterproof sealed case doubles as heat sink
- Bottom-mounted potentiometer avoids accidental changes
Two-Pack Waterproof Buck Converters
This set supplies two sealed DC-DC step-down modules rated for 8 V to 22 V input and 1 V to 15 V adjustable output at up to 3 A each. The enclosures double as heat sinks and are rated waterproof, anti-shock and dust-proof for harsh environments. A bottom-mounted potentiometer lets you trim the voltage without accidental shifts once mounted. Built-in protection covers reverse polarity, over-current, over-temperature and over-voltage conditions.
Hobbyists and Installers Needing Rugged Regulation
The converters suit anyone building radio gear, car audio, LED displays or motor drives where moisture, vibration or dust are present. The two-unit pack simplifies redundant or dual-rail designs. Projects that require input below 8 V, output above 15 V, or sustained current beyond 3 A per module cannot use these units. Applications needing isolation or synchronous rectification for higher efficiency should look at different topologies.
3 A Maximum Output Current Per Module
Each converter delivers a peak of 3 A; continuous operation at 2 A or less needs no extra cooling. The 3 A limit is the single figure that decides whether the module can power your load. Exceeding it triggers over-current protection and thermal shutdown.

Questions about this item
How do I choose between the 12 V and 15 V output settings on these converters?
The output is continuously adjustable from 1 V to 15 V with the onboard potentiometer, so you set the exact voltage your device needs rather than picking a fixed tap.
What does the 3 A rating mean when the module is installed in a project enclosure?
It can supply up to 3 A peak; for continuous operation the supplier suggests staying at 2 A or adding extra heat sinking because the sealed case relies on its outer shell for dissipation.
What input-voltage range does the DC buck converter accept and what minimum headroom is required?
It accepts 8 V to 22 V DC in, and the input must stay at least 3 V above the chosen output voltage for regulation to work.
