Transformers failing

[garlicbread]

Cut your loses now and replace the low voltage fittings with 230v fittings and get rid of the transormer situation before you end up replacing them all over time.

I havent installed a 12v downlight for some time now, for a number of reasons, much prefer 230v.

Not sure what you mean by overloaded.

An overloaded transformer is when a transformer has a load grater than what it is rated for. (i.e. A single 50w transformer running 2 50w lights)

On a more serious note, transformers can fail if they get to hot such as by having insulation around them.

I personally like these from tlc: http://www.tlc-direct.co.uk/Products/LTYT50.html[/quote

Which, once again, are NOT transformers.

It is possible the downlighters came in a kit with the transformer included, a lot of these suppliers do a contracters pack of say 6 lights/ transformers combined.
Avenue are in the same leaque as aurora in my veiw and probarly made by a major manuacturer and rebranded, contact LITEPLAN or MEDLOCK they may be able to assist

I thought transformers were rated in VA

If that was the case he would have had transformers, but he didn't have any transformers.

They are rated in VA, but 1VA = 1W when on single phase with a power factor of 1.

I used watts for simplicity reasons.

They step the voltage down, provide electrical isolation and work on electro-magnetic induction - A Transformer!

A transformer with a power factor of 1?

The item you linked to did not work on electromagnetic induction. It was labelled electronic transformer and there is no such thing. It was a switch mode power supply.
About half the posts on this thread have been about this and you still do not understand.

I know what a switch mode power supply is, it regulates the voltage by rapidly switching the power on and off electronically to maintain the set voltage.

Even if it is a switch mode power supply and not a true transformer, they are still reliable and are fine to use. We have moved on from the days of heavy toroidal transformers.

The subject of this thread seems to imply otherwise.

I installed 22x 60 va toroidal transformers in a basement flat in 1989, had to replace one last weekend ….good old newies !

sorry, for a minute i thought winston the transformer expert had slipped up, but it was his dodgy quoting again
