Power from 24VAC

Thanks for the inputs.

The Recom is a neat device http://www.recom-power.com/pdf/Powerline-AC-DC/RAC01_02-SC.pdf

However, it is rated at 90vac minimum. What happens when it is used at far below its rated minimum?

I guess that several billion wall module power supply designers are right and that a transformer is the best approach.

Does anyone have any recommendations for a tiny transformer to go in front of the bridge?

As i looked at information on transformers, it became obvious that becoming familiar with all the varieties and specifications could take a long time. Does anyone have any quick explanation on how to see the load imposed by the winding on a perpetual basis>

If this post seems redundant, I put one up a few minutes ago that didn't show up and decided to do it again.

Thanks again.
