Current Sense SMD Transformers – ECST/ECSTA Series
Eaton's ECST and ECSTA are current sense transformers for accurate sensing and measurement
Eaton's current sense transformers (ECST) are suitable for high-reliability commercial and automotive applications. The ECST provides accurate sensing and measurement of current levels in power circuits. It has a low DC resistance coil that can sense current levels and direction changes with negligible energy dissipation. The ECSTA is AEC-Q200 tested and suitable for high-reliability automotive. Both series have current capability from 7 A to 15 A with a turns ratio range from 20:1 to 200:1. They are suitable for commercial applications in industrial, computing, medical, and energy products. Current sense transformers are used to prevent overcurrent conditions or other unwanted current fault conditions in powered circuits.
