2 pins of Ø2mm diameter are available on transducer
for PCB soldering
Notes : 1) -TP version is equipped with a primary bus bar.
2) Operating at ±12V ≤ Vc < ±15V will reduce the measuring range.
3) Derating is needed to avoid excessive core heating at high frequency.

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.
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.
