Operating at
±12V
≤VC<±15V
will reduce the measuring range.
If the customer uses 1 KΩ of the load resistor, the primary current has to be limited as the
nominal. To measure the full defined measuring range, the load resistor should be at minimum 10
KΩ.
Linearity data exclude the electrical offset.
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)
Based on user needs, the sensors output range can be appropriately regulated.
According to user needs, different rated input currents and output voltages of the sensors can be
customized.
