Hello all, I’ve been given a box of these transformers and would like to see if I can work them into various power supplies.
I can’t find any information online from the Bleurgo website or elsewhere, but it looks like they were custom made for a commercial purpose - power supplies for traffic barriers so I assume the ps powered motors and they have a high current capacity. They are very heavy!
Because they aren’t centre tapped I was thinking of test wiring the secondaries in series (putting fuses before the primaries and using a bulb tester) to get a symmetrical supply.
I’ve started reading up on transformers and power supplies on the Rod Elliott site but any information that members could share on their suitability for audio circuits given their designed use and the series idea would be very welcome in the meantime.

Cheers Nico, they’re 2.45kg (5lb 6oz) each. The only rule of thumb that I could find is ‘20W per pound’. That gives about 110W. I gather VA isn’t the same but rule of thumb will do for now.
It’s going to be a little while before I plug them in, I’ve made some projects before but mains electricity still makes me nervous 😬 and it’s been a while.

Hi, can you tell me how can i test the current, VA ratings of the audio transformers?
