Amplimo: primary brown, pink and orange?

Hi,

I have a few amplimo toroids, with 3 primary wires.
Brown, pink and orange. The pink one has 2 wires in it (sleeve) that are tied together.
This toroid can be used for 220V and 231V. Does anyone know how to use these wires?

I've searched the forum, and the PDF's of Amplimo, but now they only use double-white wires.
Secondary is the usual red/yellow + blue/gray.

Kind regards,

Joris
 
Joris,
Without being certain, this is likely a dual primaries transformer.
Just connect the 230V to the brown and orange wires.
Use a variac and slowly power up without load and look at the light bulb you connected in series with say the brown wire.
If the lamp starts glowing, something is wrong.
Monitor the secondaries while your at it.
There should be no difference between 220 and 231V.
Picture?

Thanx Hugo,

I'll use a dimmer, buy one tomorrow (last 2 were broken, used them for a drill). Good Idea of you!

If anyone has a transformer of this type and you already know what wire is what... let me know!

Kind regards,

Joris
