Asta redresat inseamna aproximativ +/-35V. Studiaza documentatia integratului si in functie de sarcina pe care vrei sa o folosesti te hotarasti daca merge sau nu. E bine sa nu fortezi in tensiune integratul, mai bine il alimentezi la o tensiune mai mica decit e maximul recomandat la o anumita sarcina.

am studiat documentatia, dar nu-mi zice nicaieri cat consuma la putere maxima. de asta sunt eu nelamurit. un traf de 300w poate sa duca la putere maxima 2 astfel de integrate?

tinand cont ca un astfel de integrat scoate cam 70 W curati (nu cred ca vrei sa bagi distorsiuni in boxe) .... 2 bucati scot 140 W si cu un randament de vreo 60 - 65 % - rezulta un consum de 230 W
