Re: CBus Dimmer Compatibility

[Neil Fuller <neil.fuller@xxxxxxxxx>]

Thanks Phil

I'll get some on order.

Since posting the original question, I've done a lot of research on CBus
Forums etc. Seems the problem also relates to input capacitance so I'll
stick to one of the transformers advised by CIS.

Only problem is that the list seems to be biased towards what's
available in Australia and it's quite an old list too so I'm having
trouble locating any transformers on the list :-(

BTW Phil, I spoke with Roger Pitt the other day - He sends his regards -
Seems you have a fan there!!!!!

Cheers

Neil
