CR4211-2

Current Sensors Overview

The CR4211-2 is a self-powered AC current transducer manufactured by CR Magnetics Inc. It features a solid core, single-element design suitable for frequencies between 50 Hz and 400 Hz. The device provides an average RMS output signal proportional to the input current. It supports an input range of 0 to 2 A AC and delivers a 0-10 VDC output signal. The unit includes bidirectional conditioning and requires an output load of at least 1 MΩ. Electrical isolation is rated at 2500 VDC.

Current Sensors Feature Summary

• Self-powered operation eliminates the need for external excitation voltage
• Solid core construction ensures robust mechanical integrity
• Bidirectional module capability allows measurement of current flow in both directions

Current Sensors Applications

• AC current monitoring in power distribution systems
• Industrial control applications requiring isolated current feedback
• Equipment with operating frequencies between 50 Hz and 400 Hz

Current Sensors Procurement Notes

Verify that the specific part number matches the required input range and output signal type. Confirm that the application environment supports the specified frequency range and isolation voltage. Ensure the load impedance meets the minimum requirement to maintain signal accuracy. Check for compliance with relevant safety standards if used in regulated environments.

Current Sensors Selection Notes

Select this component when a self-powered solution is preferred over active transducers. The 2 A input range defines the maximum measurable current. The 0-10 VDC output interface must be compatible with the receiving system's input requirements. Consider the solid core design if split-core installation is not feasible or required.

Current Sensors Part Context

This model belongs to the CR4211 series of AC current transducers from CR Magnetics Inc. The series is characterized by self-powered operation and calibration to provide voltage signals proportional to AC current. Other models in the series offer different current ranges while maintaining similar functional characteristics and output types.

Current Sensors Replacement Considerations

Direct substitutes within the same series include CR4211-5 and CR4211-20, which share the same form factor and output signal type but differ in current rating. Verify that the replacement part's current range covers the application's maximum expected load.
