Re: Home made AC-AC power supply question

I have a device requiring 9v AC 2.5 Amp.

** Buy an approved plug pack with that rating.

Those are not especially easy to find, hence his question.


** Bollocks - they are quite easy to find.


So do I get a 240v-9v transformer from the electronics shop and put it
in a case, attach the correct leads and I'm done.

** No - that is not safe.

I suppose an inline fuse might be a safety precaution.

** Fuses save equipment from fire - not people from electric shock.

The transformer you have cited is not safety approved for use as an
external PSU.

It is not short circuit proof and it does not have a thermal fuse.

Buy a 9 volt AC plug pack - it will cost far less anyhow.

Idiot.

By extension, are all people who build their own power supplies idiots?


** If they build ones to replace compulsory safety approved plug packs that
came with equipment AND pay more in the process - yes, they are total
idiots.



You do point out an important advantage of "wall-wart" type
transformers -- that, in general, they are designed so that when
short-circuited, they either do not overheat, or burn out without
generating enough heat to start a fire.

** That is not what I pointed out - you fucking MORON.

The * advantage * of the approved plug pack is that it will not electrocute
you.



However, with reasonable precautions (fuse, enclosure, etc.) I don't think
what this fellow is proposing to do is dangerous.


** Errrr - just how the *** would a pig ignorant ASS like you know ??


He's only going to use it with a specific preamplifier, not connect it to
things at random.


** What irrelevant CRAP !!


And he's building one unit, not applying for safety certification.


** You are clearly not one tiny bit sane.

240 volt AC power is LETHAL.

What the fuckwit OP proposed is beyond stupid and ILLEGAL.

I hope it kills him.

I'm afraid it will kill someone else.
