If it's the ~pure sinewave version: 2:1 step-down transformer - though it will be a bit hefty at 3 KW/plug. This won't work for the modified-square-wave of the usual output, intended for switching PS's. (Dunno if Sun uses linear PSs, for some of their ovens?)

(I can't quite see why they'd be unwilling to take it back unused, though. Especially ordering in that league)

Let me know if you plan to toss the guts, please - though I haven't any immediate ideas for use of such a gadget..
