CR4180-30

Current Sensors Overview

The CR4180-30 is a True RMS AC current transducer manufactured by CR Magnetics Inc. It features a solid core design with three elements and supports an input current range of 0 to 30 A. The device provides a 4 to 20 mA DC output signal, suitable for driving loads up to 500 ohms. It operates on a 24 VDC supply voltage with a tolerance of +/- 10%. The unit functions within a frequency range of 20 Hz to 5 kHz, ensuring accurate measurement of non-sinusoidal waveforms.

Current Sensors Feature Summary

• True RMS measurement capability for accurate reading of complex AC waveforms
• Three-element solid core construction for robust signal conditioning
• Bidirectional module support enabling versatile integration in control systems

Current Sensors Applications

• Energy monitoring systems requiring precise AC current data
• Industrial power quality analysis for non-linear loads
• Legacy control hardware integration for reliable operation

Current Sensors Procurement Notes

Verify the specific model suffix against official datasheets to confirm electrical ratings and interface compatibility. Ensure the supply voltage matches the required 24 VDC specification. Confirm that the load impedance remains within the 500 ohm limit for the 4-20 mA output. Check warranty terms and lead times directly with authorized distributors before finalizing orders.

Current Sensors Selection Notes

Select this component when accurate True RMS measurement of AC currents up to 30 A is required. It is suitable for environments where waveforms are not purely sinusoidal. The solid core design eliminates the need for split-core installation. Ensure the operating frequency falls between 20 Hz and 5 kHz. Verify that the 24 VDC supply is available in the target application environment.

Current Sensors Part Context

This part belongs to the CR4180 series of True RMS AC current transducers from CR Magnetics Inc. The series includes variants with different input ranges, such as the CR4180-20 and CR4180-10. These devices are designed for professional energy monitoring applications, providing reliable current sensing solutions for industrial and commercial power systems.

Current Sensors Replacement Considerations

Consider the CR4180-20 or CR4180-10 if lower input current ranges are sufficient. Verify that the replacement maintains the same 4-20 mA output and 24 VDC supply requirements. Ensure the frequency response and True RMS accuracy meet the system specifications.
