cristybadea Posted July 23, 2013 Share Posted July 23, 2013 Am o sursa in comutatie la care primarul este distrus iremediabil.Primarul sursei este compus dintr-un microcontroler SMD care este explodat si FETT-ul P12N60C deasemenea in scurt total.Am hotarat (in lipsa c.i.-ului smd) sa inlocuiesc acest primar si m-am gandit la cel ce foloseste microcontrolerul UC 384..(2,3 sau 4) dar,nu gasesc scheme in care sa se foloseasca alaturi de acesta si optocuplorul PC817.Alta intrebare ar fi,pot folosi trafo chopper si partea cu secundarul original care,printre altele foloseste si optocuplorul mai sus mentionat?multumesc Link to comment Share on other sites More sharing options...

modoran Posted July 23, 2013 Share Posted July 23, 2013 Asta e unul din cazurile in care este recomandata folosirea unei surse UPS001. Link to comment Share on other sites More sharing options...
cristybadea Posted July 23, 2013 Author Share Posted July 23, 2013 Despre ce aparat vorbim ?Este vorba despre un scaun terapeutic(cred ca asa se numeste)Asta e unul din cazurile in care este recomandata folosirea unei surse UPS001.Da,intradevar,dar avand cateva bucati de microcontrolere as fi preferat sa nu mai bag bani in alta sursa Link to comment Share on other sites More sharing options...
