CR4150-20

Current Sensors Overview

The CR4150-20 is a True RMS AC current transducer designed for non-sinusoidal waveform measurement. It features a dual-element, double-pass-through module construction with a 20A AC detection range and two channels. The device provides a proportional 0V to 5V output signal with ±0.5% accuracy across a 20Hz to 5kHz frequency band. Powered by 24VDC at a maximum of 75mA, it supports bidirectional current flow. Operating within a 0°C to 60°C temperature range, the unit offers a 250ms response time and is suitable for DIN rail or panel mounting.

Current Sensors Feature Summary

• True RMS measurement capability for accurate analysis of chopped wave and phase-fired control systems
• Dual-element design enabling double-pass-through installation for enhanced signal integrity
• Bidirectional sensing architecture supporting both positive and negative current flow directions

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 matches the required input current rating and output signal type. Confirm regulatory compliance requirements against UL 61010B-1 and IEC 61010-1 standards for your intended deployment environment. Ensure the power supply specifications align with the 24VDC requirement and check physical mounting constraints for DIN rail or panel installation compatibility before finalizing the order.

Current Sensors Selection Notes

Select this model when precise measurement of distorted AC waveforms is necessary, as standard average-responding devices may yield inaccurate results. The dual-element configuration is preferred for applications requiring high precision and stability. Consider the 20A input range and 0-5V output compatibility with your existing data acquisition or control systems to ensure seamless integration without additional signal conditioning hardware.

Current Sensors Part Context

This component belongs to the CR4100 Series of True RMS Current Transducers manufactured by CR Magnetics. The series is engineered specifically for industrial environments where current waveforms are not purely sinusoidal. Other models in the family include single-element variants like the CR4110 and higher-range options, all sharing similar mounting styles and regulatory recognitions but differing in input ranges and element configurations.

Current Sensors Replacement Considerations

Direct substitutes within the same product line include the CR4150-15 for lower current ratings or the CR4150-25 for higher capacity needs. These alternatives maintain identical form factors, output signals, and mounting specifications, allowing for drop-in replacement if the primary current measurement range requires adjustment while preserving system interface compatibility.
