KEHIPI

KEHIPI Buck Converter DC 11-32V to 7.5V 3A 22.5W Power Adapter

SKU CH-QD91-E6DXD

Steps 11–32 V DC down to 7.5 V at 3 A with 95 % efficiency and full protection

  • ColorBlack
  • Stable 7.5 V output from 11-32 V input
  • Up to 95 % conversion efficiency reduces heat
  • Over-current, over-heat, reverse and short-circuit protection
  • Waterproof, dust-proof, moisture-proof and shock-proof enclosure
  • Compact 43 × 22 × 11 mm size fits tight spaces

Purpose and Audience

The KEHIPI buck converter steps a DC supply from 11V to 32V down to a fixed 7.5V rail at up to 3A. It suits installers who need a stable 22.5W output for vehicle, RV or solar-powered equipment such as GPS units, LED displays or small motors.

Protection and Build

The sealed ultra-thin case provides waterproof, dust-proof, moisture-proof and shock-proof performance while relying on natural cooling. Integrated safeguards include over-current, over-heating, input reverse-connection and short-circuit protection, allowing reliable operation across a -40°C to 80°C range.

Critical Specification

The converter accepts 11V to 32V input and delivers exactly 7.5V at 3A, so the load must operate within that voltage and current envelope. Devices requiring a different output voltage or more than 22.5W cannot be powered by this module.

Highlights

  • Stable 7.5 V output from 11-32 V input
  • Up to 95 % conversion efficiency reduces heat
  • Over-current, over-heat, reverse and short-circuit protection
  • Waterproof, dust-proof, moisture-proof and shock-proof enclosure
  • Compact 43 × 22 × 11 mm size fits tight spaces

Questions about this item

Will the ultra-thin protective case on this buck converter need any maintenance or replacement over time?

The ultra-thin protective case is a passive mechanical part with no moving elements; no scheduled maintenance or replacement is required beyond keeping it free of debris.

What limit appears first when the converter runs continuously at its 3 A, 22.5 W rating?

With natural cooling and up to 95 % efficiency, the first limit under sustained load is the internal temperature reaching the 80 °C maximum operating point, which triggers the intelligent overheating protection.

How much heat and noise should I expect when this unit powers a load all day inside a vehicle?

Natural cooling means no fan noise; up to 5 % of 22.5 W becomes heat dissipated through the 43 × 22 × 11 mm case, and the operating range extends to 80 °C.
