    Hello Tom Rehanek,

    Please kindly refer to 2001710003 instruction, https://images-na.ssl-images-amazon.com/images/I/B1Z5kTp++9S.pdf

    Actually they are the same items, the difference is default setting.

    You can find some battery codes directly in  menu 1 or program custom setting in menu 3.

    For any more questions, please contact us.

    Best regards.

    Hello Burns，

    Thanks for writing in.

    We are sorry factory doesn’t show us circuit diagram. This item is mainly used for audio amplifier. If you need to amplify current, you may try  signal amplifer that is used to amplify current or voltage signal.

    Any more questions, please kindly let us know.

    in reply to: Drok 200202 Board not working #36088

    Hello Apollo，

    It doesn’t matter if you connect load to output.

    We wonder whether you connect trigger siganl.  Only P3.2  doesn’t require  trigger signal.

    The other programs can’t work without trigger signal. For example, P1:  when there is  trigger signal, the relay  close for some time, and then open.

     

    Best regards.

    in reply to: Output no more than 0.3 amp #36078

    Hello Diego Monzon,

    Thanks for writing in.

    Could you please tell us more details about your operation? Before connecting your device,  did you short the output terminals and then turning  current potentiometer?

    In addition, please kindly notice the current adjustment here is for limited the max output current. It doesn’t mean actual output current is as the same as preset value.

    For example, if you set 1A , but your device only need 0.75A, actual output should be 0.75A.
    If device want to draw 2A , in that case, output will be limited to 1A.

    Best regards.

    in reply to: Set constant current on the 180080AFA #36077

    Hello Andres,

    Constant current only work under the case of 2v output.

    And please kindly notice, constant current adjustment is different from voltage adjustment.
    For most of converters, output current can’t be adjusted directly, which is decided by load mainly. The current adjustment here is for limited output current.
    For example, if you set 3A output, but  load only need to  draw 2A, the actual output is just 2A.
    When load want to draws over 4A, converter will limit output current to  3A. in that case, it is in constant current mode.

    For any more questions, please kindly let us know.

    Best regards.

    Hello Apollo,

    Thanks for writing in.

    Would you please tell us how did you program it? Did you set OP or CL time? And which work mode did you set?

    For example, if you set P3.2 and OP,CL time. It can work once power on.

    Best regards.

    Any more questions, please kindly contact us.
