Fw: Quiet Toroidal Transformer

[Gareth Cook <g@xxxxxxxxxx>]

Went to my local CEF they didnt have an Illuma units in stock. So grabbed
a 200w and a 100w Aurora transformer to see how I got on.

Well, better than expected - it cant even hear the slightest buzz now ,
whatever level of dimming !

So, if youve got CBUS or LD11's , I can heartily recommend these units.

If they are like the Ikea then in my experience they are just
transformers

And the windings go open circuit after about 2 weeks

I replace mine with Illuma  electronic Transformers

My wife has bought 2 new fancy lights - these are now plumbed into CBUS,

etc. Except - they have their own electronic transformer (they are both
LV
lightings), and if you dim, they buzz like hell. So, my option is to
bypass the internal transformer and use a Toroidal wire-wound unit. One
needs a 100W transformer, the other needs a 200W transformer.

I'd like to reduce the buzz so my best bet is to relocate the
transformer
away, and use appropriate thickness T&E cable, etc. So what I need are
quiet sealed transformers so they can put up into the ceiling void.

Anyone have any units like this they can recommend ? I have loads of the

50W sealed units, but not used any toroidal units bigger than this.
