    in reply to: Usb led lights with high CRI #30190

    Dear customer,

    Thanks for writing in.

    However we are sorry we don’t have CRI information about LED. We also consulted our factory, but LED part is sourced from outside, they  have no idea about that. Please forgive we can’t give you accurate answer.

    Any other questions, please let us know.

    Best regards.

    Hello ELVIS,

    Thanks for writing in. We are nto sure what NEMA-1450 is, google shows it is a flush mounting receptacle.

    Please kindly refer to the following wiring diagram, all of connections need to be based on it.

    Hello Akash Sawhney,

    Here is the protocol for 200220. https://www.droking.com/cs/wp-content/uploads/2017/07/200220.docx

    It doesn’t have USB terminal, you need a USB to TTL cable.

    in reply to: voltage regulator question #30155

    Hello Michael,

    Thanks for writing in.

    Before connecting battery to output terminals, our regulator show input is 20.3v, is it right?

    And aftering setting voltage and turn on output, how is it when no load?  We want to know if  votlage drops after connecting battery.

    If you can, could you please take a video to show your operation? That will be more helpful for us.

    You can share us vidoe link here or send attachment to our service email(service@droking.com)

    Best regards.
