CR4120-100

Current Sensors Overview

The CR4120-100 is a true RMS AC current transducer designed for solid core applications. It measures alternating current within an input range of 0 to 100 A AC. The device provides a ratiometric output signal ranging from 4 mA to 20 mA DC. It operates effectively across a frequency band of 20 Hz to 5 kHz. The unit requires a supply voltage of 24 VDC with a tolerance of +/-10%. It supports an output load up to 500 ohms and features a single channel configuration.

Current Sensors Feature Summary

• True RMS measurement capability for accurate reading of non-sinusoidal waveforms
• Solid core design allowing installation without circuit interruption
• Ratiometric 4-20 mA DC output signal proportional to input current

Current Sensors Applications

• Industrial motor monitoring systems
• Power distribution panel metering
• Uninterruptible power supply (UPS) feedback loops

Current Sensors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct output type and mounting configuration. Confirm that the required supply voltage matches the 24 VDC specification. Check for RoHS compliance status if environmental regulations apply to your project. Ensure the mechanical dimensions fit the intended enclosure space before finalizing procurement orders.

Current Sensors Selection Notes

Select this model when precise RMS measurement is required for AC currents up to 100 A. It is suitable for environments where current waveforms may contain harmonics or distortion. The solid core construction simplifies integration into existing busbar or cable setups. Consider the 20 Hz to 5 kHz frequency range to ensure compatibility with the system's operating frequencies.

Current Sensors Part Context

This component belongs to the CR4120 series of true RMS AC current transducers from CR Magnetics Inc. The series offers various input ranges, including 5 A, 10 A, 20 A, 30 A, and 100 A options. All models share similar ratiometric output characteristics and solid core designs, differing primarily in their maximum current sensing capacity.

Current Sensors Replacement Considerations

Cross-reference part numbers such as CR4120-50 or CR4120-200 only if the current range requirements differ. Verify that any substitute maintains the same 4-20 mA output and 24 VDC supply specifications. Ensure the replacement part supports the same frequency range and true RMS functionality.
