John,
When you find one, post the vendor here on the list.
-we looked for one also, but with ATX wiring, and could not find one that
had international compliance. The vendor is Sunpower model SAP 6300P. It
is CE marked and specifically marked with 'passes harmonics' and standard,
but there is no international compliance markings (or UL). The vendor is
aware of the harmonics issue. I don't have a model number for the straight
pc version supply. I have tested this supply and I can tell you it is much
cleaner than the non-pfc counterpart.
Since I had to probe this supply with thermocouples for the heating test, I
examined the innards and saw that the PFC circuitry is actually a module and
is more of an optional upgrade. The case of the supply was not intended for
this upgrade, but the circuit board of the supply did have a connector where
the PFC module wiring was connected. The mounting of the module was a bit
ad hoc. Interestingly, the vendor offered to upgrade the other supplies we
had on hand in the lab.
