Recommended Posts

Buna seara ! detin un kitt 1x100w subwoofer si se alimenteaza la 2 x25v,momentan il folosesc in casa la un traf 2x12v 3a. Ma gandeam daca pot ii fac un dublor de tensiune si sa il alimentez de la bateria de la masina ! se poate sa mearga ? sau pot sa ii fac vreo modificare la alimentare sa fie alimentare simpla? kitt-ul arata ca in poza . o seara buna

Dublorul nu va putea asigura 3A așa cum o face transformatorul din casă.

să îl alimentez de la bateria de la masina

De la 2 baterii de mașină, Da!

La amplificator nu ai ce sa modifici, acesta are neaparat nevoie de alimentari duble/simetrice, +/-12V este mult prea putin, ai nevoie de un traf cu 2 iesiri simetrice de macar 15Vca fiecare, daca nu ai alta solutie atunci poti apela la o sursa ridicatoare SMPS care alimentata de la acumulator auto, sa ofere la iesire undeva pe la 2*20-2*25Vcc.
