Remarks:
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100℃。
The primary conductor should be≤100℃.
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. 为了达到最佳的磁耦合,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.
