Remarks:

1. When the measured current passes through the primary pin of the sensor, there is a corresponding voltage signal output at the output end;(Note: wrong wiring may damage the sensor)

2. Products with different rated current can be designed according to the requirements of customers, and the output voltage of the sensor can be selected;

3. When the busbar is fully filled with holes, the dynamic performance is the best;

4. The temperature of primary conductor shall not exceed 100℃;
