    I have bought two Cc Buck Converter, DC-Dc constant current and voltage regulator board 5v-36v-24v step down transformer, high power led cc driver module battery charger for solar panels. At first they worked fine. Then they stopped working. I cannot adjust the potentiometers and this the voltage. I tried turning both the voltage and current counterclockwise 10 or more and still it does not work. Any ideas on how to solve the problem or do just throw them away?

    Hello Karl,

    Thanks for writing in.

    It is hard to confirm with item it is with these key words. Would you please send us product link?

    And could you please tell us more details? Can’t you change output voltage? Or is there no output current?

    If possible, would you like to show how it isby video?In that way, we can check it  and find solution quickly.

    You can share us by Youtube link or send it to service@droking.com

    Best regards.
