Am un transformator si problema este ca nu stiu sigur care este alimentarea la 220v 

Provine din dezmembrarea unei surse ups 

Cine ma poate ajuta ? 

Multumesc!

La mufa cu 4 contacte ar trebui sa fie bornele primarului....aveti nevoie de un ohmetru ca sa identificati bobinajul primar...la mufa respectiva ar trebui sa fie 2 bobine, una cu rezistenta mai mica (2 ohmi sau mai mica) si una cu rezistenta mai mare ( peste 6 ohmi)....bobina cu rezistenta mai mare este primarul si se conecteaza la 230V....spor!
