Hi Guys,

I am looking at an old (big and very heavy) transformer, and have 3 questions:

1. The output side has 3 wires: Red / Blue / Red. In faded pen on the cover it says 50V / 0V / 50V and 5amp. The input side has 4 wires: Blue / Black / Red / Yellow. In faded pen on the cover it says 10V / 0V / 220V / 240V and 2 amp. The Blue and Yellow wires are taped up, and the Black and Red wires go to a connector block. There is a fuse in line with the Red wire. Question: is it really 10V, or more like 110V and the writing is just faded?

2. Should I use the 220V or the 240V input? In my house the AC almost always measure 237V.

3. On the output side the Blue wire is taped off, and the two Reds go to connector blocks. I measure 98 and 99V AC on the connector block when the transformer is plugged in. So what would this have been used for / what would it be good for?

All information and opinions appreciated.

Thanks,
Johan
