Current Sensors datasheet and documents for CR4120-30

CR4120-30

Current Sensors Overview

The CR4120-30 is a True RMS AC current transducer from the CR4100 series, designed for non-sinusoidal waveform measurement. It features a single-element configuration with a 0.79-inch window and supports an input range of 0.5 to 600 AAC. The device provides selectable outputs including 0-5 VDC, 0-10 VDC, or 4-20 mADC, powered by 24 VDC. It offers high precision suitable for phase-fired control systems and chopped wave drivers. Mounting options include 35mm DIN rail or panel installation.

Current Sensors Feature Summary

True RMS measurement capability for accurate reading of non-sinusoidal AC waveforms
Single-element design with 0.79-inch window for direct conductor insertion
Flexible output selection including voltage and current signal options
Dual mounting compatibility with 35mm DIN rail and panel configurations

Current Sensors Applications

Phase fired controlled heaters
Quickly varying motor loads
Chopped wave form drivers
Harmonic current monitoring

Current Sensors Procurement Notes

Verify that the specific ordering suffix matches the required output signal type (0-5 VDC, 0-10 VDC, or 4-20 mADC) as defined in the official datasheet. Confirm regulatory compliance markings such as UL 61010B-1 recognition are present on the unit. Ensure the input current range aligns with the application's maximum expected load within the 0.5 to 600 AAC specification.

Current Sensors Selection Notes

Select this model when precise measurement of distorted AC currents is required. The single-element window size accommodates conductors up to 0.79 inches. Consider the available output formats for integration with PLCs or data acquisition systems. The 24 VDC power supply requirement must be accounted for in the system design.

Current Sensors Part Context

This component belongs to the CR4100 series of True RMS Current Transducers manufactured by CR Magnetics. The series is engineered for industrial environments requiring high accuracy in complex electrical systems. The CR4120 variant specifically utilizes a single-element core architecture, distinguishing it from dual-element models like the CR4150.
