Am un transformator si tot incerc sa imi dau seama cum este bobinat. Are 7 borne la iesire si dupa ce am masurat tensiunile au iesit:1-2=19,5V 1-3=0V 1-4=5,9V 1-5=0,6V 1-6=1,8V 1-7=15,8V2-3=1,2V 2-4=25,6V 2-5=13V 2-6=11,8V 2-7=30,9V3-4=5,4V 3-5=2,9V 3-6=1,8V 3-7=14,5V 4-5=2,1V 4-6=6,5V 4-7=9,8V5-6=3,1V 5-7=13,6V 6-7=23,4VVreau sa fac o sursa de laborator cu tensiune reglabila 0-30V; -15V-15V;5V si 3,3V.Acum intrebarea mea, pot sa folosesc acest transformator?Ma intereseaza la partea -15V-15V ca in rest ma descurc. Am gasit pe net ca imi trebuie transformator cu"center tap".
