AC/DC Split Core Current Transducers

The solution to your needs is fixed installed current measurements with the advantage of being DIN rail mountable and split-core to allow for quick and simple retrofitting. Using advanced Hall-Effect or Fluxgate technology to give a high level of resolution and accuracy.

The AC/DC split-core current transducers have been designed for use with a variety of data loggers, energy meters, and other measurement and monitoring equipment. They utilize either Fluxgate or advanced Hall Effect technology for accurate measurement of both AC and DC current. Their unique snap closed design allows easy connection around conductors and options of either instantaneous voltage or 4–20 mA output options make them ideal for retrofitting.

Patented strong wall mounting bracket is also available, allowing for fixing in various planes for transducer levelling.

The Transducer Range applications are accredited for use in:

  • Residual Current Monitoring applications – IEC 62020-1
  • Rail Applications – EN 50121-1 & 50121-4 for EMC and Class A1, T1 EN 50125-3 for environmental conditions for on Ballast severities for Acceleration, Shock, Bump and Vibration (broadband random)
