Buck converter with LCD and button control
The KEHIPI 200359 is a step-down module that accepts an input range of 6.5 to 36 volts and delivers an adjustable output from 1.2 to 32 volts. It is intended for engineers, hobbyists and technicians who need a compact DC-to-DC power supply with built-in metering and push-button adjustment instead of trimmer screws.
Thermals, noise and power draw
Conversion efficiency is rated at about 94 percent, so waste heat stays low at typical loads. The unit runs silently with no fan; it can sustain 3.5 amps continuously with natural convection and reach 4.5 amps when additional heat dissipation is provided. Quiescent current is approximately 30 milliamps.
Adjustable current limit decides suitability
The constant-current limit is adjustable between roughly 4.2 and 4.5 amps, which sets the maximum load the module can protect. Buyers who need a higher guaranteed current threshold or output anti-backflow protection for direct battery charging without an external diode should look elsewhere.

Questions about this item
How do I install the crystal protection case that ships as separate parts?
The case is packed separately to avoid shipping damage; after receiving the module, assemble the case around the 70.5 × 48.4 × 28 mm board before use.
What maintenance will the LCD display need over time?
The LCD shows input and output voltage, current and power with ±0.1 V and ±0.05 A accuracy; no calibration is mentioned, so normal use requires no scheduled maintenance.
At what sustained load does thermal protection become the limiting factor?
Continuous operation is rated at 3.5 A (50 W) with natural cooling; reaching 4.5 A (75 W) requires enhanced heat dissipation, so the 3.5 A limit appears first under sustained use.
