my bathroom has these downlighters (4 total) fitted, and before i moved in
i can see they have a transformer.
i want to fit the protective cover to keep the insulation off them, it wasnt re-fitted, but hesitate to cover the transformer suspecting it gets hot too...
what need i do to finish this area by fitting all the mountains of insulation lying which was moved away to do the job
thanks again

If you look more closely you will see that they are NOT transformers, but switch mode pulse width modulated power supplies.

thanks...do they get hot then...and will need to take the above advices regarding keeping them on top of the insulation??
i will anyway...

edit...i am not thinking straight tonight...must be that extra ginger beer at tea time..
but thanks all...

Nothing pedantry. Transformers and SMPT are completely different things.

so on top it is!!

He does it deliberately to get a reaction.

The ideal reaction would just be that the mods remove his posts, because...

Difficult as it is, we need to ignore him then he will either stop, or cease getting perverse pleasure out of doing what he does.

He won't do the first because he will never stop doing the second.

How many of winston's sub-2000 posts are of this type?

Including all his U0 ones?

About 3000.

This is despite pictures being posted here of manufacturers labelling their own products as "transformers".

It is well known manufacturers (or perhaps their publicity departments) are idiots. Calling a device a transformer when it isn't is the sign of an idiot. Calling a plug a plug top is the sign of an idiot.

Hopefully some of those on these forums are not idiots (I certainly am not).

Yes. You have stated it. And again

everybody is bored witless with your ridiculous and pointless nitpicking

Please, just shut up about things that don't matter to anybody (but you). The forum (and The World) will then be a happier place.

Then you deserve an Oscar and a Bafta.

The use of the correct terms is essential to avoid confusion and at times danger.

Please explain what significant confusion or dangers could arise from calling an ELV supply for lighting a transformer.

Someone may try to use it as a 50Hz 12 V supply which is what one to expect a 12V transformer to provide.

maybe i should hide....i am off to another forum
the projects forum
i am going to convert my garage to a bedroom

happy days chaps...i will return no doubt

cheers

Would that be a Switched Mode Power Transformer? No can't be.

You have to believe everything that he writes. he is infallible.
He's already told us, today

I don't posts that are wrong.

Someone may try to use it as a 50Hz 12 V supply which is what one to expect a 12V transformer to provide.

Please explain the following:

1. What sort of person would have the knowledge that a transformer would deliver an AC supply and also be unable to understand the markings on an ELV lighting supply.
   What sort of person would have that knowledge, and be confused by seeing an ELV lighting supply referred to as a transformer.
2. What danger would arise if they used an ELV lighting supply when they should have used an alternating one.

Feel free to be realistic, credible, and intelligent when replying.

 

[winston1]

1. ELV lighting supplies are typically marked 11.8 volts AC out, minimum 'x' VA, maximum 'y' VA. No mention is made of the fact that the frequency is many kHz square wave. Calling it a transformer would lead one to assume the output is a 50Hz sine wave. Virtually any intelligent person would be confused without proper markings.

2. It probably would not work.

Is number 2 a danger?
