CR4150-75

Current Sensors Overview

The CR4150-75 is a True RMS AC current transducer from the CR Magnetics CR4100 series, designed for precise measurement of non-sinusoidal waveforms. It features a dual-element split-core design with a 0.26-inch window and supports an input range of 0.5 to 30 AAC. The device provides a 4mA to 20mA output signal with ±0.5% accuracy and operates on a 24V power supply. It handles frequencies from 20Hz to 5kHz with a 250ms response time. Rated for bidirectional current detection, it mounts via DIN rail or panel installation within a 0°C to 60°C operating temperature range.

Current Sensors Feature Summary

• True RMS measurement capability ensures high precision for chopped wave and phase-fired control systems
• Dual-element split-core construction allows for easy installation without breaking the primary circuit
• Bidirectional sensing detects both positive and negative AC current flow accurately
• Compliant with UL 61010B-1, CAN/CSA-C22.2, IEC 61010-1, and BS EN 61010-1 safety standards

Current Sensors Applications

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

Current Sensors Procurement Notes

Verify that the specific part number matches the required input range and output signal type for your application. Confirm whether the standard model includes the necessary regulatory certifications for your region. Ensure the split-core window size accommodates the conductor diameter. Check if external current transformers are needed to extend the measurement range beyond the base specifications.

Current Sensors Selection Notes

Select this model when accurate measurement of distorted AC waveforms is critical. The dual-element split-core design is suitable for retrofits where opening the busbar is difficult. Choose based on the required output signal compatibility with your PLC or data acquisition system. Consider the operating temperature range and mounting constraints for the installation environment.
