PEM RCTi AC Current transducers for permanent installation and 5.0Vrms output, 250Arms to 50kArms

 The RCTi is a current transducer for permanent installation.

Simple to install and easy to retrofit, the Rogowski (sense) coil is thin, lightweight, flexible and clip-around.

The secondary output from the transducer is an instantaneous voltage proportional to the measured primary current providing an accurate, low cost, wide-band measurement of the primary current.

The RCTi is typically used with power and harmonic meters and analyzers, digital multi-meters, oscilloscopes, data-loggers and data acquisition cards.

• Traceable calibration (certificate included)
