50/60 Hz Current Sensing Transformer
This Coilcraft current sense transformer is intended for
use in measuring 50/60 Hz line currents from 0.5 to
20 Amperes rms. Typical application shown below yields
an output of 0.1 Volt per Ampere. The sensitivity may
be changed by adjusting the value of the terminating
resistance (R_T). These parts also can be used to mea-
sure 400 Hz line currents.

1. Inductance is for the secondary, tested at 1 kHz, 0.1 Vrms.
2. Square wave response deteriorates above and below this frequency.
3. Varying terminating resistance increases or decreases output Voltage/Ampere in approximate proportion to the ratio R_T / 68.
4. Operating temperature range –40°C to +85°C.
5. Electrical specifications at 25°C.
