I recommend Integrated Power Designs, a small US company located in Pennsylvania. They build switchers, but at least theirs will meet FCC regulations for sure.

Jeep, are these power supplies no-name or anything branded? What kind of filters do you use on AC and DC? HM or off-the-shelf?

With some additional input and output filtering, I use the 50A switching supplies found on ebay. Are they totally quiet? I can still find spurs outside the Amateur bands.______________________________________________________________

I would like to ask for recommendations for a 28V DC mains power supply
with worldwide availability to power 28V DC avionics at home, which
would accept 220-240V AC and which would generate low RFI. I noticed at
https://www.youtube.com/watch?v=wEHs31HJLmM <https://www.youtube.com/watch?v=wEHs31HJLmM> that the German-made PULS
GmbH SL20 power supplies were used to power a 618T-3. It seems that the
SL power supplies by PULS are no longer made, but sometimes they can be
purchased. The Taiwanese Meanwell is widely available, but they are also
reported to generate RFI, which actually disqualifies them.
Could you please share your experiences on such reasonably priced power
supplies and specify the brand and series of such units that worked well
with avionic radio equipment?
