1. All dimensions are in mm.
2. General tolerance ±1mm.
使用说明 Directions for use
1. 产品箭头的方向为Ip 方向。
Is 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. 母排充满初级穿孔时动态表现（di/dt 和响应时间）为。
The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled
with the bus bar.
4. 为了达到的磁耦合，初级线匝应绕在传感器顶部。
The primary turns should be at the top of the sensor for the best magnetic coupling.
5. 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)
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.
