I use an Astron RM-50 for each of my 12VDC Buses. I have 3 and they have been in continuous use for almost 20 years.

Switching supplies ALL generate RFI somewhere. The better ones allow you to tune the RFI frequency out of the ham bands. But it’s still RFI and will get into something or beat against something. Better just not to have it. I think of Switching Supplies as giant Wall Warts.

I should add that my 3 different Astron RM-50 Each Feed a PowerGate PG-40S to charge big AGM batteries.  Then 12V DC Buses are on the battery side and the Astrons mainly acts as a charger for the batteries.  Virtually eliminates any noise from the power supply and provides clean power to all my 12V devices.



I might add I also have a 5VDC Bus that feeds off one of the 12V DC Buses.
