230v mains to 12v or 24v USB

[Dan Brown]

Hi
Does anyone know a way this can can be done

I want to wire some usb sockets up the same type you can find in cars, up to a fused connection unit how do I go about doing this.
I know I will need a transformer of some sort but what's the best way to go about this.

I know some people are going to say why not just use the ones what come on sockets but that's not what I want so if somebody could help me out would be much appreciated

Example of the type of usb is in the picture I will attach

If you really wanted to wire your USB sockets to a fused connection unit then I would suggest looking for a compact encapsulated SMPS of similar spec to those Lucien has linked to and mount a 3A SFCU adjacent to a empty single gang box probably with a 35mm or deeper back box (depending on the size of the USB sockets you specify. The 230V power can come from the SFCU and connect to the power supply input and the output of the power supply can be connected to the USB socket via push on female crimp connectors. The power supply would fit in the empty back box and the usb socket could then be mounted in a blank plate to fix over the empty box, the location would be determined by the spacing needed for the power supply.
You would need to ensure the power supply can dissipate enough heat.
Overall expensive and complicated, but it is possible.
