ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Toroidal Transformers?

Less I2R losses, less EMI, single bolt mounting, they run cooler too.
Most of the good quality stereo equipment uses this sort of Xformer, as opposed to the E-I configuration, which is high in losses and they have a poor regulation factor(P-S).
Would anyone like to jump into the waters of this argument, it has been a really hot topic,regarding safety standards, here DownUnder?.
Your thoughts please-
