I am reposting this from another thread because its important I get this question answered before I carry on with my project.
I had mistakenly been using an over powered transformer in my last project and I'm now building an lm3876 Amp that I need a new power supply for.
I went to the surplus store and spotted a couple of 24V 75VA transformers and figured they'd do the trick.
I've just unpacked them and now I see there are three primary wires :rolleyes: . They are labelled:
120 V 1-------------)
95 V 2-------------)
0 V 3-------------)
the label says
PRI 95/120, 60Hz
SEC 24V, 75VA
So why are there three primaries. Im hoping that this is a supply for EITHER 95V or 120V and that I can just connect the appropriate wire, but I'm not going to assume that.
Can I use this thing or do I have to go buy yet another pair or transformers. |

It is exactly how you assumed: You'll have to connect 3 and 2 for 95 Volts or 3 and 1 vor 120 Valts and you'll be happy !

BTW: Where, for heaven's sake, is 95 Volts used ? |

On the far end of a really bad power distribution line?

Thats a relief.
Im started to collect a bit of a pile of transformers that didn't work out for some reason or another.
I wondered exactly the same thing about the 95V. |

The answer from our friend from the Philipines leads to the assumption that mains voltages below 100 volts are (unintentionally ?) used there.
