CR4110-150

Overview

The CR4110-150 is a True RMS AC current transducer from the CR Magnetics CR4110 series, designed for non-sinusoidal waveforms. It features a single-element split core with a 0.79-inch window and supports an input range up to 150A AC. The device provides precise measurement in chopped wave and phase-fired control systems. Key specifications include a 24 VDC power supply, bidirectional polarity, and outputs such as 0-5 VDC or 0-10 VDC. It operates within a frequency range of 20Hz to 5kHz and maintains high accuracy suitable for harmonic current detection.

Feature Summary

• True RMS measurement capability for accurate reading of non-sinusoidal AC waveforms
• Single-element split core design allowing installation without breaking the conductor
• High precision performance ideal for complex load conditions like phase-fired controls
• Bidirectional sensing with flexible output options including voltage and current signals

Applications

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

Procurement Notes

Verify the specific output configuration (e.g., 0-5V vs 0-10V) required for your system when ordering, as this variant defines the signal interface. Confirm that the 150A input rating aligns with your maximum expected current load. Ensure the 24 VDC power supply matches your available infrastructure. Check for any specific mounting hardware requirements for DIN rail or panel installation.

Selection Notes

Select the CR4110-150 when measuring AC currents exceeding standard ranges with significant harmonic distortion. Its True RMS technology ensures accuracy where average-responding meters fail. The split-core design simplifies retrofitting into existing electrical panels. Consider the 0.79-inch window size to ensure it accommodates the cable diameter. This model is preferred over solid-core types for easier maintenance and installation.

Part Context

This component belongs to the CR Magnetics CR4110 series of True RMS Current Transducers. The series is engineered for industrial environments requiring high-fidelity current monitoring. The CR4110-150 specifically addresses higher current applications using a single-element architecture. It complements other models in the family by offering extended input ranges while maintaining consistent output standards and regulatory compliance.

Replacement Considerations

Direct replacements must match the True RMS specification and 150A input range. Compatible alternatives include other CR4110 variants with adjusted input ratings if the load differs. Ensure substitute parts support the same 24 VDC supply and output signal type. Verify that the replacement also meets UL 61010B-1 and IEC 61010-1 safety standards.
