CR4111-100

Current Sensors Overview

The CR4111-100 is a True RMS AC current transducer from the CR4100 series, designed for precise measurement of non-sinusoidal waveforms. It features a single-element solid core design with a 100A input range and provides a 2-channel output. The device operates on 24VDC power (±10%) and supports outputs including 0-5 VDC, 0-10 VDC, or 4-20 mADC. It offers ±0.5% accuracy, a frequency range of 20Hz to 5kHz, and a response time of 250ms. The unit is polarized bidirectional and mounts via DIN rail or panel.

Current Sensors Feature Summary

• True RMS measurement capability ensures high precision for chopped waves and phase-fired control systems.
• Single-element solid core construction allows for direct conductor insertion without splitting.
• Bidirectional polarity detection supports accurate monitoring of alternating current flow in both directions.

Current Sensors Applications

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

Current Sensors Procurement Notes

Verify the specific output signal configuration required for your system, as the CR4111 series offers multiple voltage and current options. Confirm that the solid core window diameter accommodates the target conductor size. Ensure the 24VDC power supply meets the specified tolerance. Check regulatory compliance requirements against UL 61010B-1 and CAN/CSA-C22.2 standards before finalizing the order.

Current Sensors Selection Notes

Select this model when measuring AC currents up to 100A with high accuracy in non-sinusoidal environments. The solid core design is preferred over split-core variants when permanent installation is feasible. Consider the available output types (voltage vs. current) based on the receiving instrumentation's input impedance. The bidirectional feature is essential for applications requiring reverse current detection.

Current Sensors Part Context

This component belongs to the CR4100 Series True RMS Current Transducers, which are engineered for superior performance compared to standard transducers in complex electrical environments. The series includes various input ranges and element configurations, such as single, two, and three-element designs, catering to diverse industrial sensing needs.

Current Sensors Replacement Considerations

For equivalent specifications, consider the CR4111-30 for lower current ranges or the CR4111-600 for higher capacities within the same series. Split-core alternatives are available by appending 'S' to the prefix, though these may not hold UL recognition. Verify that any substitute maintains the True RMS architecture and bidirectional polarity.
