CR4160-10

Current Sensors Overview

The CR4160-10 is a True RMS AC current transducer from the CR Magnetics CR4100 series, designed for precise measurement of non-sinusoidal waveforms. It features a two-element solid core design with a 0.26-inch window and supports an input range of 0 to 10 AAC. The device provides a proportional 4mA to 20mA output signal and operates on a 24VDC power supply with a maximum current draw of 70mA. Key electrical specifications include a frequency response of 20Hz to 5kHz, ±0.5% accuracy, and a 250ms response time. It is bidirectional and suitable for DIN rail or panel mounting.

Current Sensors Feature Summary

• True RMS measurement capability ensures high precision for chopped wave and phase-fired control systems
• Two-element solid core construction allows for easy installation without breaking the bus bar
• Proportional 4-20mA output facilitates direct integration with standard industrial control systems

Current Sensors Applications

• Phase-fired controlled heaters
• Quickly varying motor loads
• Chopped waveform drivers
• Harmonic current monitoring

Current Sensors Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm the exact input range and output configuration. Ensure that the required load impedance meets the minimum specification for the selected output type. Confirm that the operating environment temperature remains within the stated operational limits during installation.

Current Sensors Selection Notes

Select this model when accurate measurement of distorted AC currents is required in industrial settings. The two-element design is preferred over single-element versions for applications where space constraints allow for a smaller window size. Consider the 4-20mA output option if long-distance signal transmission is necessary compared to voltage outputs.

Current Sensors Part Context

This component belongs to the CR4100 series of True RMS current transducers manufactured by CR Magnetics. The series includes various models differentiated by input ranges and element configurations. The CR4160 variant specifically utilizes a two-element architecture, offering a balance between sensitivity and physical footprint for medium-range current measurements.

Current Sensors Replacement Considerations

Direct replacements must match the True RMS functionality and two-element solid core design. Models such as CR4160-15 or CR4160-30 may serve as functional substitutes if the input range requirements are adjusted accordingly. Verify that the replacement part maintains the same 24VDC power requirement and 4-20mA output signal.
