    in reply to: DC-DC Buck Converter doesn't lower voltage #21957

    Hello Howard Marsh,
    Thanks for your reply.
    This item #180078 is the same to #180080. The only difference is without shell.
    As what we said previously, please try to turn anticlockwise the “ADJ-V” regulator for over 10 turns until output voltage is changed.
    Best regards.

    Hello Howard Marsh,
    Thanks for writing in.
    Would you please firstly help to confirm if it is the following item?
    180080

    The factory default output for this item is 20V, so you need to turn anticlockwise the “ADJ-V” regulator for over 10 turns.
    Please let us know if it can work.
    Best regards.

    Hello Sam,
    When you measure 0-10V voltage, “Vext+” and “Vext-” terminals need to be connect external power supply. The power supply should be DC10-30v.

    Hello,William Scully
    When you use “VIN-” terminal, the wiring is almost the same to the figure 1,which is connect to “VIN+”. The only difference is to change the “VIN+” into “VIN-“.
    Best regards.
