ELEKTOR - Speaker Protection
#32
AC sense se spaja na primar trafoa (dakle ako ti je napajanje +/-50VDC / 1,414 = cca 36VAC
Relej od 12V 100ohma nemoze zbog toga sto ces na izracunatom otporniku imati veliku disipaciju pa ces trebati poveci otpronik koji je na ovoj PCB predvidjen na monitranje ispod štampe...moja preporuka 24VDC relej sa 900-1100R otpora špulne i čim manjeg vremena reagiranja (OMRON, FINDER)

Temperaturni senzor je NO Type 50-100°C temperatura otpora samo je bitno da je NO (Normally Open) i da je za zadanu temperaturu...dakle kupis u lokalnoj radnji koji imaju sa tim karakteristikama...

Evo i cijelog clanka:

Samo je gore malo modificirana shema...ali to je ubiti sve isto.

Jesi radio po mojim pločicama ili radio svoje? Nabaci koju sliku...

Kod mene jos stoje PCB od te zastite vec duze vrijeme..posla je poprično na poslu pa nemam vremena za elektorniku ni da polemim zastitu i da testiram...ali treba da radi i to jako dobro...nabaci koju sliku zastite kad krenes u izradu
