Pločica po kojoj je složen desulfator:


Napravljene su 2 izmjene, prva je 4 zener diode 12V 1.3W u seriju pošto nisam imao 24V. I druga izmjena je umjesto UF4007 stavio sam PR1503, nemam UF4007 gdje kupiti trenutno...
Međutim nešto nije OK, imam 4.3V izmeću S i G i naravno pregrijavam FET, pa mogu sklop držati upaljenim tek 2-3 sec. Pregledao pločicu i veze su sve OK. Sumnjajući na problem sa FET-om skinuo sam ga i stavio drugi, imao sam isti napon između S i G. Odlemio izlazni namotaj i provjerio još jednom da li sam napravio grešku pri spajanju i sve je bilo OK. Akumulator je malo lošiji on je na oko 11.5V trenutno. Ostavio sam sve da prenoći pa ću danas dalje tražiti problem. Imam pitanje za Macolu:
Mora li baš UF4007 dioda ili može i PR1503?
Ako motam sa žicom 1mm ostaje proračun 24 namotaja na žuto /bijeloj jezgri 26mm?

Zdravo drugar,

Umeso UF4007 može PR1503 za takvu aplikaciju.
Debljina žice neće uticati na broj navoja već samo na temperaturu namotaja, a u ovom slučaju čak ni to neće biti primetno.
Sasvim je ok 4 zenerice od 12V/1.3W.

Ne vidim razlog zašto ti to ne radi. Najverovatnije si nešto pogrešio u sklapanju.
Moguće je da nisi vodio računa o tačkama na namotajima.

Kao što naš drug Samuki kaže, tu ne treba ništa da se greje a treba da se čuje tiho zujanje.

Ok, hvala na infu. Cim uhvatim trenutak pregledaću sve. Svako dobro i hvala jos jednom
