Current Transfer Ratio

Current Transfer Ratio

Das Gleichstrom-Übertragungsverhältnis (CTR = Current Transfer Ratio) gibt bei Optokopplern das Verhältnis zwischen Ein- und Ausgangsstrom bei Gleichstromsignalen oder niedrigen Signalfrequenzen an. Bei Optokopplern mit Fotodiode beträgt es 0,001-0,005 vom Eingangsstrom, bei Optokopplern mit Fototransistor 10-10000, in besonderen Fällen auch erheblich mehr.

CTR = \frac{I_C}{I_F} = \frac{Ausgangsstrom}{Eingangsstrom}
