aluneanu Posted December 27, 2014 Author Share Posted December 27, 2014 nu ma poate ajuta nimeni ,macar cu valoarea acestui rezistor enuntat in postul anterior ? O seara buna tuturor ! Link to comment
nostrom Posted December 28, 2014 Share Posted December 28, 2014 Foarte curios personal pana acum nu am intalnit la TL431 rezistenta in ANOD, acesta se conecteaza direct la masa. Link to comment
nostrom Posted December 28, 2014 Share Posted December 28, 2014 Daca sursa este cea cu doua tensiuni +B si 12V atunci intradevar anodul este legat printr-o rezistenta la masa. Confirmati daca este asa, daca da ,sper sa nu gresesc puneti o rezistenta cu valoarea aproximativa de 10 Ω evident cu respectarea watajului. Link to comment
