使用说明/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 current value can be measured at the output end

2、The best dynamic characteristics (di/dt and response time) when the input current bar is completely full of the primary side perforation.

3、The measurement resistance refers to the working power supply at ±15V, measuring DC current. If the AC current is measured, the measurement resistance is reduced to 70%.

4、The working power supply is ±12V, the measurement resistance is reduced to 75% when the DC current is measured. If the AC current is measured, the measurement resistance is reduced to 70%.
