Split-core AC current transducers

15 November 2017 Test & Measurement

LEM now provides compact split-core, low cost AC current transducers to provide a TRMS 4-20 mA output from an external 20-30 V power supply (loop powered). Separate units are available with full scale readings of 5, 10, 20, 50, 100 and 150 A.

The transducers are split-core and will accommodate conductors up to 16 mm in diameter. The 5 A units are particularly useful in providing a 4-20 mA output from existing CT’s with a 5 A output.

LEM also offers self-powered versions with 0-10 V or 0-5 V output, corresponding to the same primary currents listed above.
