    Ce este un releu \u0219i de ce e esen\u021bial<\/h3>\n\n\n\n

    Un releu este un comutator controlat electric: bobina (intrare) atrage ancora \u0219i comut\u0103 contactele (ie\u0219ire). Astfel transferi curent mare c\u0103tre sarcini (faruri, ventilatoare, pompe) folosind un curent mic de comand\u0103, protej\u00e2nd \u00eentrerup\u0103toarele, reducerile de tensiune pe trasee lungi \u0219i unitatea ECU.<\/p>\n\n\n\n
