CR4211S-150

Current Sensors Overview

The CR4211S-150 is a split-core AC current transducer designed for measuring alternating current in the range of 0 to 150 Amperes. It operates within a frequency band of 50 Hz to 400 Hz and delivers a ratiometric DC voltage output spanning 0 V to 10 V, which corresponds proportionally to the average RMS input current. The device is self-powered, deriving its operating energy directly from the sensed current, thereby eliminating the need for an external power supply. It features a single channel configuration with transformer-based sensing and conditioning. The unit supports mounting on a 35 mm DIN rail or via panel installation.

Current Sensors Feature Summary

• Self-powered operation utilizing energy from the sensed current without external power sources
• Split-core design allowing installation around conductors without circuit interruption
• Proportional 0-10 VDC output signal representing average RMS AC current

Current Sensors Applications

• Industrial current monitoring systems
• Power quality analysis equipment
• Electrical distribution panels requiring non-intrusive measurement

Current Sensors Procurement Notes

Verify that the specific application requires a 150 A rating rather than alternative models like the CR4211S-50 or CR4211S-100. Confirm compatibility with the target frequency range of 50 Hz to 400 Hz. Ensure the load impedance meets the minimum requirement of 1 M ohm for accurate signal transmission. Check for RoHS compliance requirements if applicable to the project specifications.

Current Sensors Selection Notes

Select this component when a non-intrusive measurement solution is required for AC currents up to 150 A. It is suitable for applications where avoiding circuit breakage during installation is critical due to its split-core architecture. Choose this model over powered alternatives when minimizing wiring complexity by leveraging self-powering capabilities is a priority. Ensure the output interface matches the receiving device's acceptance of a 0-10 VDC ratiometric signal.

Current Sensors Part Context

This part belongs to the CR4211S series of self-powered AC current transducers manufactured by CR Magnetics Inc. The series includes variants with different current ratings, such as the CR4211S-50 and CR4211S-100, all sharing similar functional characteristics. These devices are engineered to provide reliable proportional DC voltage outputs for industrial sensing applications.

Current Sensors Replacement Considerations

Direct substitutes include other models within the same series, specifically the CR4211S-50 and CR4211S-100, provided the current rating adjustment aligns with system requirements.
