I suggest contacting Cherokee International in Tustin, CA at 714 544 6665. According to my records from 1997 they had a new (at that time) MQT250 series power supplies that come close to your requirements. Maybe with a little tweeking they can get you what you want.

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.
