KEHIPI

KEHIPI DROK-2PCS-40W-DC Buck Boost Converter 2pcs 6-36V to 0.5-36V 4.5A 40W

SKU CH-NAA9-G4176

Pack of two buck-boost converters adjusting 6.0-36 V input to 0.5-36 V at up to 4.5 A with colour LCD readout and multiple protections

  • Adjustable output from 0.5 V to 36 V covers diverse loads
  • 88 % conversion efficiency reduces heat and energy loss
  • Colour LCD shows voltage and current at 0.01 V and 0.001 A resolution
  • Nine protection modes include over-voltage, over-current and over-temperature safeguards
  • Silicone keypads resist wear from repeated pressing for long service life

Pack of Two Adjustable DC-DC Converters

This pack contains two KEHIPI DROK buck-boost converters that accept 6.0-36V input and deliver 0.5-36V at up to 4.5A. Each unit provides 40W maximum output with 88% conversion efficiency and a colour LCD showing voltage and current readings. The silicone keypad allows precise adjustment of output parameters and protection thresholds. Designed for hobbyists, RV solar installations and bench power supply builds.

Suits DIY Power Supply Builders.

Builders who need a pair of compact, adjustable modules for charging batteries, driving LED arrays or regulating solar input will find the dual pack convenient. The extensive protection suite includes reverse-input, over-voltage, over-current, over-power, over-temperature and programmable capacity or energy limits. Users requiring sustained currents above 4.5A per channel or input voltages outside the 6-36V range should look at higher-rated alternatives.

4.5A Peak Output Current Per Module

The single specification that decides fit is the 4.5A maximum output current, adjustable down to 0.001A with 0.001A resolution. Over-current protection defaults to 4.6A and can be set between 0.001A and 4.6A. If your load demands more than 4.5A continuous, this converter will trip its protection; if the load stays within that limit, the module delivers the requested voltage with ±0.3% accuracy after calibration.

Questions about this item

What maintenance or replacement will the two buck-boost converters need over time?

Silicone keypads are rated for prolonged pressing without wear, and the colour LCD protects the PCB pads from oxidation, so no routine part swaps are expected.

Which limit appears first when running both modules continuously at 4.5 A?

Over-temperature protection triggers at the default 60 °C threshold, while conversion efficiency is 88 %.

How much heat and noise do the converters produce during all-day operation?

Built-in buzzer sounds only on protection events; silent otherwise, and over-temperature protection activates at 60 °C.
