Using transformer secondary windings

Can I use both secondary windings to power separate loads?

 

I have a need for two 4.5VAC power supplies.

I have a transformer that is 9VAC with a center tap. I would like to connect one load to one 4.5VAC O/P and the other load to the other 4.5VAC. I'm assuming I can do this, provided I don't exceed the max current rating. It has been a long time since I have dabbled this low in analogue. I was looking for some reassurance or refresher.

    Thanks JC for the reply. The AC loads are two small model railroad buildings that require 4.5VAC. It looks like they have some internal electronics to generate power for the few LEDS scatter around. It…

    As far as I can remember you can use a half wave rectifier on both output taps and the share the center tap as ground there is no problem with the circuits connecting to each other. Using half wave rectification…

    Only need the AC. I have no need for the rectifier stuff.
