Re: Xfmr core size vs. freq

It all depends on whether you are winding, or just buying.

A larger core allows a lower frequency primary to be
wound on it.

Right, Phil. That has absolutely nothing to do with power
transformers. You want to minimize both the iron, and the copper losses
to keep the cost down. BTW, how well do your microphone transformers
work at 120 VAC?

As I need only a small amount of power I was wondering if someone has already tested the following setup: A lab sine generator set to 50/60Hz, a low cost audio amplifier (units up to 500W are available for 50$ or so on ebay, and should be happy with a 50Hz signal), and a 48V/220V transformer driven on its secondary side. ...
