DC buck-boost regulator for DIY power projects

This KEHIPI module converts a DC 6-30V input into an adjustable DC 0.5-30V output at up to 4A and 60W. It is built for hobbyists and engineers who need a compact step-up and step-down converter with constant-current and constant-voltage modes. The clear black enclosure includes an LCD that shows voltage and current together. Short-circuit, over-temperature and input reverse-polarity protection are integrated.

Fits into a build as a standalone power board

The unit accepts wiring through terminal blocks or solder pads labelled VIN and VOUT. A USB port on the case provides a convenient 5V tap for charging or low-power devices. An opening on the bottom of the shell allows an optional fan to be added when output exceeds 2.5A or 35W. Operating temperature range spans -20 to +70°C, so external heat-sinking may be required in sustained high-power use. The board is explicitly not intended for computers or laptops.

Suits bench testing, battery charging

Makers who need a protected, metered supply for prototyping, high-power LED constant-current driving or battery charging will find the adjustable limits and calibration function useful. Builders who require AC mains input, isolated outputs or regulatory certifications for commercial equipment should look at alternative solutions. Anyone planning continuous operation above 50W must plan additional cooling beyond the supplied case.

Questions about this item

At what output current does the KEHIPI regulator need extra heat dissipation?

The manufacturer recommends enhanced cooling when output exceeds 2.5 A or 35 W, and notes the power tube should stay below 70 °C.

How loud or hot does the unit get when running continuously at high load?

There is no built-in fan; a fan opening on the bottom allows you to add one, and the over-temperature protection shuts off output if the power tube exceeds 70 °C.

What input source must I already have to power this module?

A DC supply between 6 V and 30 V connected to the VIN terminals or solder pads is required.
