Safety
This transducer must be used in electric/electronic
equipment with respect to applicable standards and
safety requirements in accordance with the
manufacturer's operating instructions.
Remarks
•
I
S
is positive when
I
P
flows in the direction of the arrow.
•
Temperature of the primary conductor should not exceed
90°C.
•
Dynamic performances (di/dt and response time) are best
with a single bar completely filling the primary hole.
•
In order to achieve the best magnetic coupling, the primary
windings have to be wound over the top edge of the device.
•
This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...),
please contact us.

Caution, risk of electrical shock
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.
