    I have connected to 50 volt power supply and I have two issues. the voltage measured by multiple meters reads significantly higher than what the regulator is set to. for example, if i set it to 9 volts, it will display 9 volts but my meter will read 12 volts. it is consistently off through out the range. is there a way to calibrate it? any way for me to troubleshoot it?

    the second issue is i cant get it to go above ~3 amps. i have a fan that draws about 6 amps at 12 volts that will run using the drok up to about 3 amps at 12 volts, using CC or only makes it to about 9 volts using CV, and then it resets its self.
    thanks for any advice.

    Hello adrian pharms,
    It seems your problem is not the same to the last one.
    The last problem is about calibration.
    Is it convenienct for you to take a short video to show how it is?
    And please tell us some parameters, for example, input voltage, output voltage/current, load and etc.
    You can send the video to service#droking dot com ( please replace # with @).
    We will try our best to find solution for you.
    Best regards.
