Rated by test certificate and CB report, or by the sales dept-infected spec sheet?
That is, what is the rating on the unit's label? You can configure most variacs to provide well above the input voltage, but this may do strange stuff to the source impendence. Use a really really really big variac, or use an electronic source (Ametek, Chroma, etc).

We typically test at 90 Vac and 240 Vac. Many supplies I see now are rated up to 264 Vac though. Is anyone testing at 264V? Are there variacs out there to bump the input voltage, since our generator can't go much above 240?
