    Existing reviews of DC-DC Buck Converter, 24V to 12V
    Steady step down converter
    This DC-DC buck converter works great, I was using a charge controller to provide 12 volts to my 12V components to rotate the solar panels. This converter is much simpler and works way better. Keeps my voltage at 12 volts and I will be able to add more panels too.

    Good price and good value DC-DC converter
    Lots of DC-DC boost/buck converters for sale on store. So I just found the right one to meet my need. Used this converter to step down DC 24v to 12v. Product was as described and does the job as it should. No issues at all. Good price and good value.

    I really like this DC-DC buck converter
    Hi I am interested in your ATO-DCDC-2412. But I see in the specs the minimum input voltage is 18 VDC. What happened if the input voltage drops below 18V?

    If the voltage drops below 18V, the output voltage will be unstable. And we can customize for about 2V less than the normal operating voltage range (16V input voltage).
