CS2106L

Document 150 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 (RT). These parts also can be used to measure 400 Hz line currents. To request free evaluation samples, contact Coilcraft or visit www.coilcraft.com. Part number CS2106L 1. 2. 3. 4. 5.

Square wave response deteriorates above and below this frequency. Varying terminating resistance increases or decreases output Voltage/Ampere in approximate proportion to the ratio RT / 68. Operating temperature range –40°C to +85°C. Electrical specifications at 25°C.
