Application examples
According to EN 50178 and IEC 61010-1 standards and following conditions :
Safety
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.
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.

In Refout mode at T
The minimal impedance loading the ref pin should be > 220 k
Internal impedance = 600 . For most applications you need
to buffer this output to feed it into an ADC for example.
Please see the operation principle on the other side.
