使用说明 Directions for use |
1.产品箭头的方向为Ip方向 。
It will be in a forward direction when the Ip flows according to the direction of the arrowhead.
2. 初级导体温度不应超过120℃ 。
The primary conductor should be≤120℃.
3. 母排完全充满初级穿孔时动态表现（di/dt和响应时间）为最佳。
The dynamic performance (di/dt and the response time)is the best when the primary hole is fully filled with the bus bar.
4. 当待测电流从传感器穿过 ，即可在输出端测得电压大小。(注意：错误的接线可能导致传感器损坏)
When the current will be measured goes through a sensor,the voltage will be measured at the output end.
(Note: The false wiring may result in the damage of the sensor)
5. 传感器的输出幅度可根据用户需要进行适当调节 。
Customs can adjustOutput amplitudeof the sensorby needs.
6. 可按用户需求定制不同额定输入电流和输出电压的传感器 。
Custom design in the different rated input current and the output voltage are available.
