ELEKTOR - Speaker Protection
Spojio zaštitu i neradi delay kako treba, znači čim se spoji napajanje za cca 2sekunde se aktivira relej a trebao bi za 4sekunde...sad idem da premjerim otpornike dal nisam sa delay otpornikom stavio koji pogrešno.

Kada je relej uključen na njemu mjerim napon od 23,02VDC što je OK.
Kratko spojio sam konektor za temepraturnu zaštitu relej se odmah isključi i za cca 2sekunde natrag se uključi pa ovo valjda radi OK pošto kad je temperaturni senzor vruć otpor mu je jako mali i aktivira zaštitu (kao što sam ja sada napravio kratkospajanjem te zaštite), a kad se senzor ohladi otpor raste i relej se uključi kao i na početku sa početnim delayem koji treba da je cca 4sekunde po shemi a ja dobijam cca 2sec pa moram to da rješim i onda na kraju test sa 1,5V AAA baterijom sa i obrnutim polaritetom..samo da se rješi ovo sa delayem...elektrolit mi je 47uF/63V i 100k otpornik što bi trebalo da da delay od 4,7sekunde (mjerio sam sa Capacitor Meter i 47uF mi daje 42,3uF a otpornik je 99,85k) što treba da daje točno 4,22sekunde ili ti očekivanih 4sekunde a ja dobijam 2sec..evo i video snimke.

Napon napajanja mi je 50,7VDC što kada se oduzme pad napona na D1 (0,7V) daje točnih i čistih 50VDC koji preko otpornika 1k2 daje na releju 23,02VDC

R10 je 10k a R11 1k2/3W, s time što je napon na R10(10k) točno 36VDC što daje struju baze 3,6mA (a treba da je 3-5mA) što je OK.
Shema je:
