The CR4111S-50 from CR Magnetics is a True RMS AC Current Transducer that is designed for accurate measurement in applications where AC current waveforms are not purely sinusoidal. It requires an input current of 0 - 50 A. This current transducer provides an output current of 0.004 - 0.02 A and a linearity error of 10 - 100% (full-scale). It offers highly accurate and precise measurements, making them perfect for phase-fired controlled heaters, motor loads with rapid changes, and chopped waveform drivers. It is ideal for monitoring harmonic currents in complex electrical systems.

This true RMS current transducer is also compatible with external current transformers. It is available in a DIN rail-mount package that measures 76.7 x 30.8 mm and is ideal for phase-fired controlled heaters, rapidly varying motor loads, and chopped waveform driver applications.
