The MROA Series from Frer Srl are True RMS AC Current Transducers. They require a supply voltage (DC) of 60 - 415 V and a supply current of up to 5 A. These transducers provide an output current of 0 - 20 mA. They provide precise true RMS sensing and calibration, making it an ideal choice to conduct accurate measurements of even the most distorted waveforms. These current transducers offer low response time and residual ripples. They are available in DIN rail-mount packages that measure 110 x 70 mm.
