[SunRescue] 690mp & 240VAC

Yeah, I belive that is correct, but you'd need a RMS meter.  The problem
with a "standard converter" is most ovens/motors/dryers/etc don't care
about ground, and so have phase-1, phase-2, and neutral.  No
ground.  Almost all computers/electronics/etc have Phase-1, Phase-2,
Neutral, and most important Ground.
