Usage elucidation:

1、The sensor connects the line according to the structural graph declaration , put the measured current through the magnetic core hole , then you can detect out the correspondent voltage according to the measured current from the output.(note : incorrect connection may lead to the damage of the sensor)

2、The output amplitude of the sensor can do some adequate adjustment according to the customer’s demands.

3、We can customize the sensor of different rated input current and output voltage according to the customer’s demands.
