SolderingIronDriver by Bogdan Kecman

Hmm, malkice je kriticno jer ce ispravljen napon biti 42V a to je blizu absolutne granice za LM2574 koja je 45V.
Sa druge strane taj napon nece biti bas 42V jer imamo potrosnju za MCU i LCD i kada je grejac iskljucen.
Sa trece strane imamo varijaciju mreznog napona … Smile
Tesko je predvideti ovako napamet, trebalo bi da se zna kolika je potrosnja celog uredja kada je grejac iskljucen pa da se uradi neki pred-test sa ekivaletnim opterecenjem za taj tvoj konkretan trafo.
Ili da stavis neki blider otpornik 1-2W da ga optereti malo kako bi drzao napon ispod kriticne granice.
