Our current interest is in transformers. The requirement is given in W, not VA. If we are looking for a 50-60 VA power supply, when do we run out of runway for the 1/2W standby spec. in terms of core, or is it simply a matter of how big can we stand?

By the way, I forgot to mention in my quest -- >I was looking for ac-ac supplies. I found many ac-dc supplies... AC-AC supplies? Like a transformer? Is the off-load limit of 0.5 W true watts or VA? If it's true watts, you may be able to meet it with an oversize transformer core, depending on what output VA you want. As is usual, more data required! -- OOO - Own Opinions Only.
