50A/4-20mA SPLIT CASE

Item number CTR05000

CTR Series transducers combine a current transformer and a signal conditioner into a single package. This provides higher accuracy, lower wiring costs, easier installation and saves valuable panel space. The CTR Series transducers are available in 4-20 mA output only. The CTR Series provides a “True RMS” output on distorted waveforms found on VFD or SCR outputs, and on linear loads in “noisy” power environments. Select the CTR Series for variable speed or SCR controlled loads. The current waveform of a typical linear load is a pure sine wave. In VFD and SCR applications, however, output waveforms are rough approximations of a sine wave. There are numerous spikes and dips in each cycle. CTR transducers use a mathematical algorithm called “True RMS”, that integrates the actual waveform over time. The output is the amperage component of the true power (heating value) of the AC current waveform. True RMS is the only way to accurately measure distorted AC waveforms.
