使用说明/Remarks
错误的接线可能导致传感器损坏.传感器通电后,当被测电流从传感器箭头方向穿过,即可在输出端测得同相电流值.
Incorrect connection may lead to the damage of the sensor.ISN is positive when the IP flows in the direction of the arrow.
当输入电流排完全充满原边穿孔时动态特性最佳(di/dt和响应时间).
Dynamic performance (di/dt and response time)are best with a primary bar in the center of the through-hole.
测量小于25A的电流时,可以用多匝线圈,以便得到最好的精度,但考虑到散热问题,传感器的长期工作电流应小于额定输入电流.
When measuring currents less than 25A, multi-turn coils can be used in order to obtain the best accuracy, but considering the heat dissipation problem, the long-term working current of the sensor should be less than the rated input current.
