◆     switching power supplies(SMPS)

Advantages                            Typical applications

◆ insulation between input and output

◆ no insertion loss      

◆ removable construction being easy to installation                 

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、  When the measured current flows along the sensor’s arrowhead direction, the output gains the synchronism voltage.

4、  When the measured current fills the aperture, it can gain optimal dynamic characteristics

1、  the sensor connects the line according to the structural graph description, put the measured current through the magnetic core perforation,then it can measures the corresponding voltage  according to the measured current from the output.(Note : erroneous wire splice may results to the damage of the sensor)

2、  the output amplitude of the sensor can do some adequate adjustment according to the customer's demand.

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