    Hakko FX-888D toroidal transformer upgrade to 240V

    Hi,
    I was using a Singway 120-240V < > voltage convertor from Ebay but it was not good enough, it popped and the fuse in the Hakko blew also.
    I have been looking at replacing the Hakko 110V transformer (I can trade the transformer if anyone needs it) with a toroidal transformer.
    I have looked at projects and they seem to have been successful but also seem to have used single Voltage Out toroidal transformers. But, the only toroidal transformers I found all have dual 12V or dual 24V Voltage Out.
    It seems I should have to use a single Voltage Out toroidal transformer and not a Dual Voltage Out toroidal transformer.
    May I have some advice please.

    you connect the 12v windings in series.

        Please note that Toroid transformer has high in rush current thane E-core transformer so it may pop the fuse that you have right now.

          Thanks for this information ( I Did not know this about Toroid transformers )

          I have only seen this type of transformer a few times in a few devices I have seen them at some electronic surplus supply stores online I have been tempted a few times in the past to buy some but not have any experience using them I have not bought any of them

          I will read about this type of transformers from the website links that you provide

          Thanks again for information
