（2）If
the customer uses 10KΩ of the load resistor, the primary current has to be limited as

（4）Please
refer to derating curves in the technical file to avoid excessive core heating at
high frequency.

◆Instructions
of use
1. When the test current passes through the sensors you can get the size of the output voltage.
(Warning: wrong connection may lead to sensors damage)
2. Based on user needs, the sensors output range can be appropriately regulated.
3. According to user needs, different rated input currents and output voltages of the sensors can
be customized.
