How much effect will linear power supplies’ EMI have on machine controls?

April 15, 2015
A machine builder asks about the trade-offs between a switched mode power supply and linear regulated.

We’re trying to save cabinet space by changing from a linear regulated power supply to a switched mode power supply. From what I understand, we’ll get a higher power density with a smaller footprint, while the power factor is about the same. My biggest concern is, with so many devices offering built-in intelligence these days, will a switching power supply create so much electromagnetic interference that it will cause a controls problem on our form, fill and seal machines?

Any mounting recommendations to reduce EMI? What about unregulated? And how close are power supplies to offering their own control capabilities, or is that already available?
