How to Make a Power Supply

<< < (11/16) > >>

Bernd:
Darren,

You might want to add a fuse on the mains side of the tranny for saftey sake. Other than that it looks OK. :thumbup:

Bernd

Darren:
Good point Bernd,

It easy to forget what comes without question for some of us could be missed by others  :thumbup:

You could also add a fuse after the transformer, say 5A or if you know you current demand is low like these motors then a 3A would be better.

But, DO fit a mains fuse as Bernd suggested.

Bernd:
As far as I know and have seen in electrical magazines in the US all such projects have a fuse in line on the incoming voltage to the transformer.

Seems each country has different electrical codes for such devises.

Looking good Darren. Carry on and sorry for the interruption.  :thumbup:

Darren:
In the UK many electrical goods do not have an internal fuse.

This is because our wall socket plugs have internal fuses. This makes it quite hard to connect anything to the mains supply without a fuse.


Do I understand from your post that US plugs don't have internal fuses?  :scratch:

Divided he ad:
Thank you for the parts list Darren :thumbup:


I'll get figuring out the stuff and where to buy it ASAP  :)




Got to get my mill powered  :dremel:


The plug thing.... Odly the other side of the pond do not have fuses in the plugs.... like the French (And I suppose other European countries?)
It seems a little under protected to me..... But hey, someone must know what they're doing? right?  :zap:
