The new universal current transducer MCR-SL-CUC-X00 I from Phoenix Contact can sense currents with any waveform and convert them into a standard analogue 4–20 mA signal. These modules replace the complex DC current measurement with its associated losses that is classically implemented using shunt resistors.
As a result of their low tolerances, these CTs can also be used in control circuits to track solar panels or to adjust the pitch of wind turbines. The new current transducers are available in versions from 0 to 300 A that can detect currents in the frequency range from 20 to 6000 Hz.
The modules are suited for use in small control cabinets as a result of their compact dimensions and the wide range of available mounting options. Pluggable connection technology allows electrical connections to the transducer to be quickly and reliably established.
