CAS / CASR / CKSR Mechanical differences
* The internal reference voltage is provided on a secondary pin or can be forced by an external reference voltage
The CKSR has one more primary pin (4 primary pins in
total) than the CAS and CASR models (3 primary pins in
total) making it incompatible with the footprint of these last
8 models. It

the performances mentioned in the CKSR 6-NP data sheet.
* Output voltage CKSR 6-NP is used with internal reference.

Using this layout configuration, the current measured by
the transducer is still 6 A
as when connected in series the primary pins have 4 loops
(instead of 1 when connected in parallel) through the aperture
of the transducer.
Then 4 loops, carrying 1.5 A each, results into a total current of
6 A.t (Amps.turn). Finally, the transducer “sees” a 6 A current.
