    Hello Chris Swallow,

    To confirm which part it is, would you like to show that  by images? You can show pictures here or send it to service@droking,com.

    And may I know more details about the operation? For example, input voltage/current, what kind of load is connected?

    Best regards,

    DROK

    Hello RayC,

    Please hold the square button for more than 3 seconds when it is in start screen. Just like  holding down trigangel button to reset no-load current.

    Any more questions, please let us know.

    in reply to: DC-DC boost Converter #46722

    Hello Ugochukwu anyoha，

    We are sorry it may be hard to make one with such large output current.

    And most of voltage converters can’t decide how much current the load should draw. They just give a limit on output current. Assume output current can be controlled by  tachometer, that just change current limit value instead of actual load current.

    Best regards.

    Hello ，

    Is it this item?  200206

    We don’t recommend that way. It  is hard to ensure both of output parameters stay same, that  is easy to burn the module.

    Best regards,
