For the electronic measurement of currents : DC, AC, pulsed, mixed,
with a galvanic isolation between the primary circuit (high power)
and the secondary circuit (electronic circuit).
All Data are given with a RL = 10 kW

Notes : 1) It is possible to overdrive VREF with an external reference voltage
between 2 - 2.8 V providing its ability to sink or source approximately
2.5 mA.
ApplicationDomain
· Industrial
2) Excluding offset and hysteresis.
3) Small signal only to avoid excessive heatings of the magnetic core.

This transducer must be used in electric/electronic equipment
with respect to applicable standards and safety requirements
in accordance with the following manufacturer's operating
instructions.
Remarks
Caution, risk of electrical shock
· VOUT is positive when IP flows from terminals 1, 3, 5, 7 (IN) to
terminals 2, 4, 6, 8 (OUT).
· Temperature of the primary conductors should not exceed
120°C.
When operating the transducer, certain parts of the module can
carry hazardous voltage (eg. primary busbar, power supply).
Ignoring this warning can lead to injury and/or cause serious
damage.
This transducer is a built-in device, whose conducting parts
must be inaccessible after installation.
A protective housing or additional shield could be used.
Main supply must be able to be disconnected.
