Hi all,
been a while since I posted anything on this forum :)

But here's the problem, I've got a 2.3KW variac, and do not know how to wire it correctly,
there is a diagram that looks like this on the back

E --------||
||
220 ----||-----S
--------- ||
125-----||-----(A)
||
0 --------|| -----(0)

this || needa be inbetween to get the correct picture :)

(--) is a screw terminal

then on the bottom screw terminals it looks like this:
here is || the stuff (transformer and all ) in between

(--) 220 ||
(--)125 || (--) ground symbol arrow with long strike getting smaller (hope that explains the symbol)looks like this
(--) A || (--) 0
(--) E || (--) S

i hope this could make a clear picture, or else I could make a real picture of it :)
It's a German transformer says made in Germany, it also lists a type: sst250/10e-e75g.
if I google that it gives me 4 links which are in German, which I can't read, and don't list any schematics :)
I hope you guys can help me out because it would be a waste if I'd destroy the transformer.

If you have made an ASCII drawing in a fixed-space font,
you can paste it in here and select the "code" format (a button that looks like <>).

   220 ----||-----S

Here is an interactive tool for making flow charts as "ASCII images".

I bet there is something similar for schematics.
Don't need fancy rendering of component symbols.

Hi Rvd Tuuk:

Why you do not take a picture of the back of Variac? a JPEG picture will be ease to all people help you.

Of course a variac is a usefuul device for any experimenter. Do not demolish!

Also, please indicate what voltage will be the supply and the load.
