CR4211S-5

Current Sensors Overview

The CR4211S-5 is a self-powered AC current transducer from the CR4211S series by CR Magnetics Inc. It utilizes a split-core design with a single element to measure alternating currents within a 0-5 A input range. The device operates at frequencies between 50 Hz and 400 Hz, providing a proportional DC voltage output powered directly by the sensed current. It features an accuracy of ±0.5% and supports a minimum output load of 1 MΩ. The unit offers 2500 VDC isolation and functions within a temperature range of 0°C to +60°C.

Current Sensors Feature Summary

• Self-powered operation utilizing energy from the sensed current for proportional DC voltage output
• Split-core construction allowing non-intrusive installation on conductors
• High isolation rating of 2500 VDC for safety in electrical circuits

Current Sensors Applications

• AC current monitoring in power distribution systems
• Integration into industrial control panels requiring isolated current feedback
• Energy management systems measuring low-amperage AC loads

Current Sensors Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure compatibility with required mounting hardware and connector types. Confirm that the application environment remains within the specified 0°C to +60°C operating range. Check for RoHS compliance status if environmental regulations apply to your project. Ensure the input current does not exceed the 5 A RMS limit to prevent saturation or damage to the internal sensing element.

Current Sensors Selection Notes

Select this model when a non-invasive measurement solution is required for AC currents up to 5 A. The self-powered nature eliminates the need for an external excitation supply, simplifying wiring. Consider the split-core form factor for retrofits where breaking the conductor is impractical. Verify that the system frequency falls within the 50-400 Hz operational bandwidth before deployment.

Current Sensors Part Context

This component belongs to the CR4211S series of average RMS self-powered AC current transducers. The series includes variants with different current ratings, such as the CR4211S-50 and CR4211S-150, designed for higher amperage applications. All models in this line share the same fundamental split-core architecture and self-powered output characteristics, differing primarily in their rated input ranges.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing this unit, ensure the new component matches the 0-5 A input range, 50-400 Hz frequency response, and 2500 VDC isolation requirements. Verify physical dimensions and terminal configurations for mechanical fit.
