If I use a Pulse Width Modulator on say a fan, will it reduce the cost of running it, if it is slowed down?
Not something I'm planning on doing, just wondering!

isnt this the equivelant of a VSD?

i beleive they do offer savings on pumps ect, but this is more to do with the mechanical load rather than the electrical charachteristics. Dont takethis as gospel though, im sure somebody more knowledgebale than me will be alongto confirm or correct the above.
