Notes:
1)
2)
3)
Operating at ±12V
≤VC<±15V will reduce
the measuring range.
If the customer uses 1KΩ
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.
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.
