"Poor man's" regulacija lemilice 24V
Evo sinoc se nesto lemilo i konacno, nakon pola godine stajanja u fioci, "Poor man's" regulacija lemilice 24V je gotova. Ručka je tipa HQ-SOLDER/IR, trafo sec- 24VAC priblizno 100W (overkill) Wink
Prvi pokušaj da proradi je uspešan.
P1 podešen na 1.98V da bi dobio 450°C, Led sveti a grejač radi.
Ali kad merim temperaturu vrha dobijem samo 215°C. Metoda merenja je kao kod TDA (Kalaj je na granici topljenja)

Nanesem malo kalaja na pljosnati vrh lemilice i uronim termo sondu u njega kako bi se temperatura bolje prenela.
Prema tabeli sa posta #115 trebalo bi da pri temperaturi od 215°C na termoparu da bude 8.940mV ali kod mene su 13,9mV. Pomislio sam da mi mozda metoda merenja temperature nevalja ali kad sam malo bolje pregledao šta čika google nudi u vezi termopara ručke tipa HQ-SOLDER/IR izašlo je da ova ručka nema  termopar tip ''K'', več termopar tip "E".
Evo ovde moze da se vidi sta piše

E ovo več priblizno odgovara temperatura/mV koje sam ja merio.

Prema tabeli 207°C daje 13.9mV na termoparu.
E sad ono veliko pitanje "šta sad?" Vidim da su neki pre mene vec koristili regulaciju za HQ-SOLDER/IR i da je bilo problema

Kako mogu najbezbolnije da rešim ovaj problem. Dali moze samo podešavanjem P1? Ili mozda da probam sa promenom ulaznog otpora R12 ?
