costi002 Posted October 15, 2012 Share Posted October 15, 2012 Teoretic ar iesi un autotransformator, practic, numai tu ne poti spune . Succes Quote Link to comment Share on other sites More sharing options...
salsa Posted October 15, 2012 Share Posted October 15, 2012 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...
