Guest horia_b Posted February 25, 2007 Share Posted February 25, 2007 Se poate monta un amplicator de casa, cu alimetarea de 220V in masina folosind un invetor de tensiune 12V-220V? Link to comment
luc Posted February 25, 2007 Share Posted February 25, 2007 pai se poate,dar vei suporta pierderile celor doua trafuri la 50hz,care nu sunt neglijabile(in jur de 15 sau 20% bucata).mai sunt si alte pierderi dar alea sunt in convertor si in amplificator.de ex la un consum de 500w ,50 de wati ii disipa tranzistorii din convertor,inca 50w se pierd in transformatorul ridicator, inca 50 in cel coborator, inca 100 se disipa in amplificatorul audio ,si restul putere care ramane e RMS pe difuzor Link to comment
ionut20 Posted February 25, 2007 Share Posted February 25, 2007 Se poate, dar nu e o solutie recomandata pt folosire de durata.Pe post de invertor poti folosi un ups, si in loc de acumulatorul sau, legi acumulatorul masinii. Link to comment
