使用说明/Remarks
1.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压值。
Incorrect wiring may cause damage to the sensor. After the sensor is powered on, when the measured current passes through the arrow direction of the sensor, the in-phase voltage value can be measured at the output end.
2.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)。
The dynamic characteristics (di/dt and response time) are best when the input current row completely fills the primary side perforation.
3.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IPN。
When measuring currents less than 25A, multi-turn coils can be used to get the best accuracy, but in consideration of heat dissipation, the long-term operating current of the sensor should be less than the rated input current IPN.
