    I'm trying to make an ac adapter for this lcd touchscreen monitor I've got and google is failing me while trying to figure out what kind of plug this thing has on it. I called the manufacturer and they wanted an astonishing 200.00 for a replacement adapter so thats completely out of the question.

    It's a round plug with threads on the outside and has 3 pins in it arranged in a triangular fashion with a flat spot in the plastic between one of the pins and the outside of the plug socket. The monitor requires 24v dc 3.75a

    If anyone can help it would be greatly appreciated. Here's a pic, don't mind the boogered up looking pins I'm taking care of that.

    I'll take a look in the morning and see what it says inside the plug hopefully that would help.

    No idea what it is called, however, if the adaptor is broken but ccable is fine, can you not just attach the cable to a new powersupply? If you do that, the colour of the wires inside the cable should tell you the polarity as well.

    Edit: I miss read, sorry. Hopefully it is helpful anyway.

    Also, could you not just hardwire a powersupply or find a broken one and use it for parts?

    if the adapter is broken and the cable is fine you might find another transformer to fit the bill and use the other cable with another plug on the other end to convert it as well

    How about removing that 3 prong plug and convert it with plug available to you..
