My university likes to throw out old equipment, so naturally, when they do, I have a field day.
Today they threw out a gigantic uninterruptable power supply (APC). It had a 250V plug and several 240 and 120 sockets on the output. It was probably used for backup in our Semiconductor Manufacturing Laboratory (I go to Rochester Institute of Tech) .
Anyway, someone had gutted it before I got there and I found some absolutely massive transformers (about 8" cubes). There were also some smaller ones. I have always found that transformers are difficult to find datasheets for.
does anyone know what the basic markings on transformers mean?
The one I have on my desk right now says:
430-2054A.3 (could be -3)
CLASS 130(B)Z150H
E154515 LEI-4 OH10
One side has 3 wires, orange, black, white
the other side has 5 wires:
3 are heavier gauge than all the others and are red, white, black
2 are the same guage as the wires on the other side and are orange and brown.
I assume the heavier gauge are the primary but im not sure why the secondary would be split over the two sides. It may be a 220V transformer, instead of 110... not sure how to tell.
I have 2 other transformers in my car. I can get the numbers from them but if theres something simple about transformer numbering that im missing i can find them myself once i learn what it is.
Thanks
absolutely massive transformer numbers:
430-7128
CLASS 180(H) R333H
LEI-4 E154515 2D08
giant white and black wires on one side
blue, black, red, white wires on other side into plastic connector.
