CR4150-15

Current Sensors Overview

The CR4150-15 is a True RMS AC current transducer designed for non-sinusoidal waveforms. It features a dual-element, bidirectional design with a 15A AC input range and two channels. The device provides a proportional 0V to 5V output signal with ±0.5% accuracy. Operating on 24V DC power with a maximum current draw of 75mA, it supports frequencies from 20Hz to 5kHz and has a response time of 250ms. It functions within a temperature range of 0°C to 60°C and supports DIN rail or panel mounting.

Current Sensors Feature Summary

• True RMS measurement capability for accurate readings of chopped wave and phase-fired control systems
• Dual-element construction allowing dual pass-through installation for simplified wiring
• Bidirectional sensing suitable for both positive and negative current flow detection
• High precision output with low error margin for reliable industrial monitoring

Current Sensors Applications

• Phase fired controlled heaters
• Quickly varying motor loads
• Chopped wave form drivers
• Harmonic current analysis

Current Sensors Procurement Notes

Verify the specific model suffix matches the required input range and output configuration. Confirm that the 24V DC power supply aligns with system voltage standards. Ensure the dual-element window size accommodates the conductor diameter. Check regulatory compliance requirements against UL 61010B-1 and IEC 61010-1 standards for your region. Validate mounting type compatibility with existing DIN rails or panel cutouts before ordering.

Current Sensors Selection Notes

Select this model when measuring AC currents exceeding standard single-element windows or requiring dual-pass convenience. The 15A rating suits moderate load applications where high precision is critical. Choose the 0-5V output if interfacing with PLCs or data acquisition systems requiring low-voltage signals. Consider the 20Hz to 5kHz frequency range for applications involving variable frequency drives or non-standard waveforms rather than pure 50/60Hz sine waves.

Current Sensors Part Context

This component belongs to the CR4100 Series of True RMS Current Transducers by CR Magnetics. The series includes variants like CR4110, CR4120, and CR4160, offering different input ranges and element configurations. The CR4150 specifically denotes the dual-element variant, distinguishing it from single-element models in the same family. All units share common features such as 24V DC operation and robust regulatory certifications.

Current Sensors Replacement Considerations

Direct substitutes include other CR4150 variants with different current ratings, such as CR4150-10 or CR4150-0.5, if the input range differs. For single-element needs, consider CR4110 or CR4120 series models. Verify that any replacement maintains the True RMS specification and dual-pass architecture if those features are essential for the installation.
