DC current measuring transducers pass-through type. Measured current range - 250A.
E1842 is meant for linear transducing 50 Hz AC current into unified DC output signal and can be used for current control in elecrical systems with nominal voltage up to 660 V. A distinctive feature of this type of transducers is pass-through construction: there is no galvanical conection between transducer and measurement circuits.
Transducers are produced with accordance with ТУ 4227-008-49501860-02.
