Za kontrolu grijaca se koristi trijak, a njegova specificnost je ta da se sam iskljucuje kada struja padne na nulu (kao i tiristor). Zato ti treba AC napon jer, ako iskoristis DC napon, trijak se nikada nece iskljuciti i grijac ce raditi non-stop (jednom kad se ukljuci, naravno).

Ja na ovoj tvojoj modificiranoj shemi vidim i kondenzator poslije greca, zato sam rekao da nece raditi kako treba. Ako ostavis samo grec, bez kondenzatora poslije njega, raditi ce OK.

Na Smps nisam stavio ni diode ni kondezatore znaci samo prigusnicu , da nije do frekvencije rada Smps ? Nece da se upali grijac tj triak da provede.

kod mrežnog napona frekvencija je 50Hz a kod smps...toliko kHz. trijak ne znam da li može da se aktivira i deaktivira tako brzo,namijenjeno je mrežnoj frekvenciji i toga se treba držati a ne taj parametar uvećati za hiljadu puta...

Probaj na trafou bez greca.
To ti je najsigurnije za štap i lemilicu.

E jbg.
Nađi bilo kakav izvor 48V a da nije SMPS ili na taj svoj SMPS stavi neke brze diodi i malo kapaciteta...

Trazicu neki trafo, a ako stavim diode i kondezatore na Smps onda ce biti istosmjerna a ima 2* 25v.
