Am looking at a multiple outlet nominal 24VDC variable power supply (Factory Configurable 1.8 - 52VDC 80A, 80A, 14A, 40A, 40A) On the PRF Data Sheet is states: EMI & EMC Conducted Noise EN55022 CLASS

That will depend HOW it fails to meet Class B -- and who it affects. It's not unusual to find switch mode PS's that meet Class B above 500 KHz or 1 Mhz -- and fail it at, say, 100 or 200 KHz and low

Looked at both sites (I am an aggressive Google user) and as is often the case the answer is buried out there and I may spend hours looking and still not find the technically relevant answer I seek.

Doc, I know what you mean. It is hard to turn an EMC standard into reality in the ham shack. Industrial-type power supplies are not normally sold to consumers and so probably are never evaluated to t

Doc, I erred in saying there was a 10 dB difference between Class A and Class B. 10 dB difference is for radiated emissions; for conducted, it's worse. Limits are specified for particular bandwidths

I think I will go back to the original plan. Start with a pair of 12v batteries in series and drop the voltage to 19 and 16 v using a couple of zeners, some resistors, and regulators. I am guessing t

Doc, There are some very significant differences between CL A and CL B devices in the EMC world. If you really do intend to use radios while this thing is running, and also if the antennas for those
