Measuring transducer E1849

Active and reactive power measuring transducers. Meant for use in 380V circuits without external primary transformers.

Description E1849

Е1849 appointment:

E1849 is meant for linear transducing of active and reactive power of three phase AC circuits into unified DC signals and can be used in systems of automative control of energetic objects of different branches of industry. Also it can be used for monitoring current values of active and reactive power. Digital processing of signal is applied.

Transducers are manufactured according to ТУ  4227-006-49501860-02.
