CR4111-40

Current Sensors Overview

The CR4111-40 is a True RMS AC current transducer from the CR Magnetics CR4100 series, designed for precise measurement of non-sinusoidal waveforms. It features a single-element solid core design with a 40A input range and a 0.79-inch window. The device provides a 0-10 VDC output signal, operates on 24 VDC power, and supports frequencies from 20Hz to 5kHz. With ±0.5% accuracy and bidirectional capability, it mounts via 35mm DIN rail or panel installation.

Current Sensors Feature Summary

• True RMS measurement capability for accurate reading of chopped waves and phase-fired control systems
• Single-element solid core construction with integrated conditioning module
• Bidirectional detection for both positive and negative current flow analysis
• Regulatory compliance including UL 61010B-1 and IEC 61010-1 standards

Current Sensors Applications

• Phase-fired controlled heating systems
• Quickly varying motor load monitoring
• Chopped waveform driver diagnostics
• Harmonic current analysis in power distribution

Current Sensors Procurement Notes

Verify that the specific part number CR4111-40 matches the required 40A input range and 0-10 VDC output configuration. Confirm the solid core design is suitable for the conductor size, as opposed to split-core variants which require an 'S' suffix. Ensure the application environment falls within the specified 0°C to 60°C operating temperature range and utilizes a 24 VDC power supply compatible with the device's maximum current consumption limits.

Current Sensors Selection Notes

Select this model when high precision is required for distorted AC waveforms where standard transducers fail. The 40A rating suits moderate current applications without needing external current transformers. Choose the 0-10 VDC output if the receiving instrumentation prefers voltage signals over current loops. Consider the DIN rail mount for industrial control panels or panel mount for direct enclosure integration based on space constraints.

Current Sensors Part Context

This component belongs to the CR4100 series of True RMS Current Transducers and Transmitters by CR Magnetics Inc. The series is engineered for applications requiring higher accuracy than standard transducers, specifically targeting non-sinusoidal AC currents. The CR4111 variant denotes a single-element design with a larger window capacity compared to two-element models, offering flexibility in conductor insertion while maintaining strict regulatory certifications.

Current Sensors Replacement Considerations

Direct substitutes include other CR4111 models with different current ratings, such as CR4111-20 (20A) or CR4111-30 (30A), provided the output signal and mounting remain compatible. Split-core versions like CR4111-40S offer similar electrical performance but are not UL recognized. Cross-brand replacements must match the True RMS specification, 20Hz-5kHz frequency range, and 24VDC power requirements.
