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 installation and use environment of the product should be free from conductive dust and corrosion. Severe vibration or high temperature may also cause product damage. Please pay attention to the use occasion.
3、The best dynamic characteristics (di/dt and response time) when the input current bar is completely full of the primary side perforation. For optimal magnetic coupling, the primary side turns should be wound around the top of the sensor.
