ITZ 2000-SPR FLEX ULTRASTAB
Programming example to 125 A
:
An ITZ 2000-SPR transducer head programmed to 125 A will produce 1 A when the primary current is equal to 125 A.
The current conversion ratio of the transducer is then:
Programming example to 375 A:
An ITZ 2000-SPR transducer head programmed to 375 A will produce 1 A when the primary current is equal to 375 A.
The current conversion ratio of the transducer is then:
Analog output connector
Normally the provided analog output cable should be used. It is also possible to configure your own output cable, bearing the
