Va salut. vreau sa stiu ce se va intimpla cu un transformator 12V. daca fiind conectat la priza electrica si se racordeaza o borna de iesire a transformatorului cu o faza de 220V. va mirosi a fum sau nu :) ?

Daca stii ce faci vei obtine un autotransformator la a carui iesire vei avea 220+/- 12V, in functie de care borna o legi la retea.E foarte util daca ai nevoie sa ridici/cobori tensiunea retelei. E principiul dupa care UPS-ul "reguleaza" tensiunea.Daca nu stii ce faci urmeaza sfatul din semnatura mea. Oricum noi nu te putem opri sa incerci...
