I just bought this and it does not change the output voltage. Other than a defective  unit, any suggestions?

thanks

Hello Izzy，

Thanks for writing in.

Is it this item? 090455  To check what wrong is, would you please tell us more details about your operation parameters? For example, input voltage, load. Did you connect load?

It would be appreciated if you can take a video to show us the operation. In that way, we can check it more carefully.

If it is hard to attach vidoe here, you can send it to our service email(service@droking.com)

Best regards.
