Notes : Performance data are given for steady phase of the transducer.
Transitory period after power on lasts typically less than 2 min.
Please refer to characterization report for details.
Please don't put the high voltage between the secondary pins and fixing
pins. If it must be so, don't exceed the 2.5 kV between these pins with the
maximum isolation distance.

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.
