CR4110-25

Current Sensors Overview

The CR4110-25 is a True RMS AC current transducer from the CR4100 series, designed for non-sinusoidal waveform sensing. It features a 25A primary current rating and bidirectional operation. The device provides an analog output with ±0.5% accuracy across a frequency range of 20Hz to 5kHz. Powered by a 24V supply with a maximum current draw of 25mA, it offers a 250ms response time. Operating within a temperature range of 0°C to 60°C, it supports DIN rail and panel mounting configurations.

Current Sensors Feature Summary

• True RMS measurement capability for accurate sensing of non-sinusoidal AC waveforms
• Bidirectional current detection allowing for positive and negative flow monitoring
• High precision performance with ±0.5% accuracy specification
• Integrated conditioning sensor combined with transformer technology

Current Sensors Applications

• Power quality analysis in electrical distribution systems
• Monitoring non-linear loads such as variable frequency drives
• Industrial automation control loops requiring precise AC current feedback
• Energy management systems tracking complex harmonic currents

Current Sensors Procurement Notes

Verify that the specific order matches the CR4110-25 designation to ensure the 25A rating is correct, as other variants exist in the series. Confirm RoHS compliance status if environmental regulations apply to your project. Check that the 24V power requirement aligns with your system's available voltage rails. Ensure the physical mounting style (DIN rail or panel) fits your enclosure design constraints before finalizing the purchase.

Current Sensors Selection Notes

Select this component when measuring AC currents that contain significant harmonic distortion or are not purely sinusoidal. The True RMS feature distinguishes it from standard average-responding sensors. Consider the 25A limit carefully; if higher currents are expected, choose a model with a larger primary rating. The bidirectional nature makes it suitable for applications where current direction may reverse. Verify the 20Hz lower frequency limit meets your operational requirements.

Current Sensors Part Context

This unit belongs to the CR4100 series of current transducers manufactured by CR Magnetics Inc. The series combines transformer isolation with signal conditioning electronics. Unlike DC transducers in the Series 52 or combined AC/DC units in Series 54, this specific model is optimized for AC applications. It serves as a specialized solution for industrial environments requiring reliable, high-accuracy current monitoring under varying load conditions.

Current Sensors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must verify compatibility manually if sourcing alternatives. Ensure any replacement maintains the True RMS functionality and 25A rating. Check that the replacement also supports bidirectional operation and the same 24V supply requirement.
