KEHIPI Drok VH-2405 Buck Boost Converter 5-30V to 0.6-30V 35W LCD Power Adapter

KEHIPI Drok VH-2405 Buck Boost Converter

The KEHIPI Drok VH-2405 is a DC buck boost converter module that steps input voltage from 5.0V to 30V down or up to an adjustable 0.6V to 30V output. It delivers up to 4.0A continuous current with a rated output power of 35W. A built-in LCD screen shows real-time voltage and current readings with 0.01V and 0.001A resolution. The unit includes constant voltage and constant current modes with a lock function to prevent accidental adjustment.

For bench testing and low-power DC systems

This module suits hobbyists, technicians, and builders who need a compact adjustable DC supply for prototyping, battery charging, or LED driver applications. The thickened heat sink supports sustained 35W operation, while an external cooling fan can raise the limit to 50W. It is not for users requiring AC mains input, isolated output, or power levels above 50W. Buyers needing fixed-voltage regulated adapters or higher current capability should look at alternative power solutions.

35W rated output with 88% conversion efficiency

The converter operates at a 180kHz switching frequency and achieves 88% conversion efficiency under typical loads. Over-voltage, over-current, over-power, and over-temperature protections engage automatically, with low-voltage protection activating below 4.7V input. Output anti-backflow and short-circuit protection protect connected loads. The manufacturer recommends an input above 7V to obtain full rated output power.
