IEC Power Supply options

    What are the parts (Please post links) needed for this design for the IEC Mod?

    Thanks!!! :) :D
    As far as the power supply goes: basically it needs a transformer inside it, something like this :

    or this :

    My only real concern is making sure that there is enough space to fit one into the enclosure under the main board (which will sit about 20mm lower than the enclosures upper face, allowing a bit for components). There is also a significant amount of space which is taken up by the I/O board. If we can get accurate measurement of the enclosure we could do a mock up, but first hand experience from someone who has already done it would be better. :D :D :D

    Also on the power supply : I'm fairly sure that the transformer is the only thing needed, I've been poking around looking for any potential issues with EMI radiation that could screw with audio, but no one seems to be talking about it as a concern, so fingers crossed it's a non issue. Toroidal transformers as I've linked to are designed for low noise applications so I'm hopefully just over thinking it. Also the ones I've linked to would work, but are significantly (2 to 4 times) more powerful than is necessary.

    I'll be hopefully using a box from this thread; viewtopic.php?f=16&t=605

    Can anyone that has fitted an IEC style power supply help? :) :) :)
  • I think that the first one is the right choice. The other is for PCB... I can tell you that in this box there is room enough to place a toroidal transformer of 3 Ampere. The transformer that i used is well over the needed power, but was unused in a drawer. Apparently no EMI issue...

    Hello, there´s any of this kind of transformer on Mouser site?
    I´m going to order the boom from mouser and I would like order together a nice trasformer, thanks mates.
