The VS3100/M38 PS has two caps, rated at 250VDC each.  I'm presuming the
the other VS3100's are fairly similar.  Now I've just got to find a way
to test it :-)  Hmmmm, I think I have 220VAC washer and dryer hookups
around here somewhere. I also noticed that the M38's supply was rated at
348W which seems pretty impressive considering the VS3100's small size.
But then maybe this is because they used the same PS in the roomier M48 as
well.  

The VS2000's label only states support of 110-120VAC, but I'll have a look
inside to see what options may exist.

Thanks to everyone for the responses on this question.
