CURRENT TRANSDUCERS

All current transducer components are for high precision AC/DC current analysis. Older IT-transducers are analogue compensated, the new CT- and IN-sensors digital compensated. The digital compensation results in a very high DC-accuracy combined with a very high frequency range and low phase shift.
