Properties:

  • Small dimensions
  • Wide measuring range (3X In)
  • Low weight
  • Low power consumption (several W)
  • Non-invasive measurement (zero loss)
 
Principle of operation O/L

     The magnetic flux generated by the primary current Ip is concentrated in the magnetic core in the gap in which the Hall plate is located. The voltage output signal from the Hall sensor after amplification in the electronics tells the instantaneous value of the primary current.
     Based on this principle, constructional families of current transducers are made to measure currents from 5 A to 20 kA in the frequency band from 0 to 50 kHz.
     The measurement accuracy of the rated current at 25oC reaches a maximum of 1%.
