CR4120-75

True RMS AC Current Transducer The CR4100 Series True RMS Current Transducers and Transmitters are designed for applications where AC current waveforms are not purely sinusoidal. More precise and accurate than other transducers, these devices are ideal in chopped wave and phase fired control systems. DIN RAIL / PANEL MOUNT, TRUE RMS Applications Phase fired controlled heaters Quickly varying motor loads Chopped wave form drivers Harmonic currents CR4110 CR4120 CR4111 Single Element - 0.79” Window 0.1 to 600 AAC Input Range Features 35mm DIN Rail or Panel Mount Available with 0-5 VDC, 0-10 VDC, 4-20 mADC output 24 VDC powered Use with external current transformers Highest precision available Connection diagram printed on case Transducers C Regulatory Agencies CR4150 Recognized to meet UL 61010B-1 Constructed to meet CAN/CSA-C22.2, No. 61010-1-2004 Meets requirement of IEC 61010-1 and BS EN 61010-1 CR4160 Two Element - 0 .26” Window 0.1 to 30 AAC Input Range E199795 Use a 5 Amp Secondary Current Transformer to extend the ranges of all CR Magnetics Current Transducers CR4170 CR4180 Three Element - 0.26” Window 0.1 to 30 AAC Input Range Add suffix for input range PART NUMBERS CR4110(S) CR4111(S) CR4120(S) CR4150 CR4160 CR4170 CR4180 - Single element with 0 - 5 VDC output (split core design) Single element with 0 - 10 VDC output (split core design) Single element with 4 - 20 mADC output (split core design) Two element with 0 - 5 VDC output ** Two element with 4 to 20 mADC output ** Three element with 0 - 5 VDC output ** Three element with 4 - 20 mADC output ** *Two and three element transducers are available only in ranges of 0.1 to 30 AAC The Professional Energy Monitoring Company M N TI ISO 9001:2008 Quality Management System All single phase current transducers are available in split core design.
