1. Summary

CTI series transducer is used to test on DC, AC and pulse current. The primary side is insulated from the secondary side. The close loop transducer applied Hall theory has high precision, straight linearity, low temperature drift, low insertion loss, and strong anti-interference ability. CTI series have been widely used in the current test of power supply field.

CTI series include CT-050I(50A), CT-100I(100A), CT-200I(200A) and CT-300I(300A). The test aperture diameter is 20 mm, easy to use and reliable.
