使用說明 Directions for use
1. 產(chǎn)品箭頭的方向?yàn)镮p 方向。
Is will be in a forward direction when the Ip flows according to the direction of the arrowhead.
2. 初級(jí)導(dǎo)體溫度不應(yīng)超過120℃。
The primary conductor should be≤120℃.
3. 母排充滿初級(jí)穿孔時(shí)動(dòng)態(tài)表現(xiàn)（di/dt 和響應(yīng)時(shí)間）為。
The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled
with the bus bar.
4. 為了達(dá)到的磁耦合，初級(jí)線匝應(yīng)繞在傳感器頂部。
The primary turns should be at the top of the sensor for the best magnetic coupling.
5. 當(dāng)待測(cè)電流從傳感器穿過，即可在輸出端測(cè)得電壓大小。(注意：錯(cuò)誤的接線可能導(dǎo)致傳感器損壞)。
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. 可按用戶需求定制不同額定輸入電流和輸出電壓的傳感器。
Custom design in the different rated input current and the output voltage are available.
