Military Sepc Large Mains Transformer

[Shockhazard]

This is a large bespoke made mains transformer removed from a 300 watt military power amp.
Weighs around 8kg.
Works fine hopefully someone can find a use for it.
Only £70 plus the postage.
Specs hand written on top of transformer.

Oops last is not for sale as it’s an output transformer. Clicked wrong picture.

 

[jean-paul]

You forgot to mention output voltage(s).

 

[Shockhazard]

Did write them down somewhere have to have a look through me piles of paper see if I can find them.
If not I’ll run it on variac tomorrow post them.
It’s 220/50vac input not 115vac.

 

[Shockhazard]

Sorry thinking of wrong transformer variable taps on this one. Written on it Der wake up in a minute.

 

[jean-paul]

It is not 220V but 115/230V.

 

[Shockhazard]

Right found piece of paper.
It’s all Scribble but I’ve put 9 as CT
8-10 99v
8-9 49v
9-10 49v
Plus 24v reading which is or looks like I wrote 6 & 7 added together so obviously 12v each.
Transformers are not my forte but that’s obviously the readings I measured.

Obviously the other taps are for 115 or 230 on input side.

To be honest it’s a beauty and workmanship is top spec in my opinion.

Hope that helps if not I’ll take some readings tomorrow.

OK but all that beauty will need to fit in a project of a member.

Maybe you could advertise is as being a military transformer with 115/230V 50 Hz primaries and 2 x 50V and 2 x 12V secondaries (all with a central CT
so likely not separate windings). Now the question will follow how many Ampères the 2 x 50V and the 2 x 12V secondaries can deliver.

 

[Shockhazard]

You got it but last picture ignore as it’s an output tranny not mains.

Since it is in post #1 you can still delete the wrong picture.
