[RFI] Sorenson DCS 55-55 PS Clean?

[Tim Groat]

You can read the manual here: 
<http://theelectrostore.com/datasheets/dcs55-55_nig.pdf> (warning: long 
file!). On page 4, it says the power supply is certified to meet FCC Class 
"A" emissions. In other words, it's going to make more RF noise than a 
class "B" product, at least at some frequencies. If it passed class "B" 
standards, they would almost certainly say so because that opens additional 
sales opportunities.

Also take a look at the safety information on page 2. Among other things, 
this unit needs a dedicated 208-240V AC power line similar to what you'd 
need for a legal-limit power amplifier. That's to be expected, since this 
*is* a 2.5kW power supply.

So I won't say don't use it--Sorenson is a respected company that make fine 
industrial products. But do understand what you're getting into. Powering 
an amateur radio transceiver isn't what they had in mind when they designed 
and built this heavy-duty brute.
