Hi Dan,

    If it is the same variac you referred to in your previous post, then I
believe it is 240/280V each section. The size would be your best cue,
however. If each section is the same size as a standard 7.5A variac, then it
is probably 140V. But if it is much larger, it's 280.
    Also, 9A is a standard rating for Superior 280V units, but not for 140's.

Hope that helps,
John
