Instructions

1.Incorrect wiring may cause the damage of sensor.

2.When the measured current through the center hole of the sensor, the current will be measured at the output end.

3.The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.

4.User can adjust the output extent of sensor if necessary.

5.Rated input current and output voltage of sensor can be customized.
