Model# CTRS

RMS Split-Core Current Transformer/Transducer

The CTRS series of transducers provides a non-contact, loop powered, method of current measurement. The dc output is directly proportional to the true RMS value of ac window current. Measurement ranges of  5A to 40K are available.

  • Accurate measurement of the true RMS value of input signal.
  • Split Core 5A thru 1000A sensors without loss of accuracy.
  • Open circuit protection.
  • Flexible rogowski coils (air core CTs) are used for current measurement ranges of 1kAac and larger.
