Schema Radio cu ceas Radiowecker Modell V602 UKW 88-108Mhz


Recommended Posts

Buna ziua,Are cumva cineva schema radioreceptorului german Radiowecker Modell V602 UKW 88-108Mhz...Este un radioreceptor cu ceas digital, cu alarma, cum sunt prevazute in general astfel de dispozitive.Are transformatorul de retea cu primarul ars.In secundar exista însă 4 iesiri, şi aici am eu nelamuririle, daca erau numai trei era mai simplu, adică banuiam ca e o iesire cu 2 capete cu o priza mediana si apoi redresorul normal.Asa mai apare inca un conductor si inca o dioda in plus fata de cele 4 din punte.Am incercat sa il alimentez cu o baterie de 9 Volţi(e prevăzut şi cu aşa ceva) dar nu indica nimic, nici displayul nu clipeşte, nici radio nu porneste.M-ar avantaja si niste sfaturi, pentru ce ar avea transformatorul de retea asa ceva, o fi cumva ceva clasic in schemele unor astfel de radioreceptoare?Şi o schema apropiata ar fi buna.Va multumesc
