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.
