Unique, IP67, flexible split-core AC current sensor implementing high accuracy Rogowski Coil technology

 

 

 

 

Main characteristics:

 

  • Class accuracy 0.5 according to IEC 61869 regardless of primary conductor position
  • Rated insulation voltage 1kV CATIII
  • From 10 to 10000 ARMS
  • Thin, light and flexible split-core current sensor for easy installation anywhere
  • Perfect Loop Technology for no-discontinuity coil clasp
  • Better than 0.65% accuracy regardless of the primary conductor’s position
  • Almost perfect linearity, no saturation, no upper limit in current rating
  • Internal shield
  • Low output voltage proportional to the rate of change (derivative) of the primary current (electronic integrator required): 22.5 mV/kA @ 50Hz

 

 

Features:

  • 6.1 mm gauge with sensing apertures of Ø 35mm to 300mm
  • Mass: 130g
  • Bandwidth: 50/60 Hz, up to 700kHz in open circuit condition (no load)
  • Operating range: -40°C to +80°C

 

 

Standard compliance:


  • The products are CE certified (2014/30/EU) regarding their safety according to the European directive 2014/35/EU and tested according to the standards IEC 61010-1.
  • IEC 61869 for Instrument transformers performances
  • UL 2808 (in progress)

 

 

Remarks:

  • Fast clip-on mounting whilst cable is connected
  • First Rogowski coil suitable for Class 0.5 power monitors and energy meters
  • Slot expected to fix the loop on conductor with a cable tie
  • Ø 2 mm hole to pass a security seal
