CR4211-70

Current Sensors Overview

The CR4211-70 is a self-powered AC current transducer from the CR4200 series by CR Magnetics Inc. It features a solid core, single-element design with one channel and bidirectional module conditioning. The device supports an input range of 0-70 AAC and operates within a frequency band of 50Hz to 400Hz. It provides a proportional 0-10 VDC output signal calibrated for average RMS input AC current. The unit includes 2500 VDC isolation and requires an output load of at least 1M ohm.

Current Sensors Feature Summary

• Self-powered operation eliminates need for external excitation power
• Solid core construction allows installation without circuit interruption
• Bidirectional module conditioning enables accurate measurement in both directions

Current Sensors Applications

• Multi-point current monitoring systems
• AC power quality analysis
• Industrial equipment current sensing

Current Sensors Procurement Notes

Verify that the specific order matches the CR4211-70 part number exactly, as the CR4200 series contains variants with different current ratings such as 20A, 50A, and 150A. Confirm the requirement for a minimum 1M ohm output load impedance to ensure proper signal integrity. Check for RoHS compliance status if required by your manufacturing standards.

Current Sensors Selection Notes

Select this component when a 70A AC current rating is required with a 0-10 VDC analog output. Ensure the application frequency falls between 50Hz and 400Hz. This model is suitable for solid-core installations where non-intrusive monitoring is necessary. Consider the 2500 VDC isolation level for safety requirements in high-voltage environments.

Current Sensors Part Context

This part belongs to the CR4200 series of current sensors. It shares the same transformer-based conditioning architecture as other models in the family, differing primarily in its specific 70A current rating. The series offers various amperage options to suit different industrial monitoring needs while maintaining consistent output characteristics.

Current Sensors Replacement Considerations

Direct substitutes within the same series include the CR4211-20, CR4211-50, and CR4211-150. These alternatives share identical form factors and output signals but differ in their maximum current ratings. Verify that the replacement rating meets or exceeds the system's peak current demands.
