Remarks

1.Incorrect wiring may cause damage to the sensor. After the sensor is powered on, when the measured current passes through the arrow direction of the sensor, the in-phase voltage value can be measured at the output end.

2.The output amplitude of the sensor can be adjusted according to the user's needs.

3.Sensors with different rated input current and output voltage can be customized according to user requirements.
