使用说明Directions for use
1, 当待测电流从传感器输入脚流过,即可在输出 端测得电流大小.(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 currentwill be measured at the output
end.(Note:The false wiring may result in the
damage of the sensor)
2, 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 bestwhen the primary hole is fully
filled with thebus bar.
3,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 inputcurrent and the output voltage are available.
