I have been given a small transformer which apparently came from a 110V UPS for a computer. I did not get a wiring diagram or colour coding for the input output and would be grateful for any help.
I think (dangerous) that the heavier red and black are the + and _ of the higher voltage input (line and neutral) although I have no idea what the blue wire is for - some kind of sense?. The output or lighter wires are red, yellow (lower DC voltages?) green (ground?) and black (ground or what??).
Can anyone advise? Pic is attached.
