CR4210S-50

Current Sensors Overview

The CR4210S-50 is a split-core AC current transducer manufactured by CR Magnetics Inc. It provides a 0–5 VDC analog output proportional to the measured AC current. The device features a bidirectional module with one channel and includes integrated conditioning for transformer-based sensing. Designed for 50A AC applications, it utilizes a split-core configuration to facilitate installation around conductors without breaking the circuit. The unit is RoHS compliant and lead-free.

Current Sensors Feature Summary

• Split-core design allows non-intrusive installation around existing busbars or cables
• Provides a linear 0–5 VDC analog output signal proportional to primary current
• Integrated signal conditioning ensures accurate measurement of bidirectional AC currents

Current Sensors Applications

• Industrial power distribution monitoring systems
• Electrical panel metering and control circuits
• Energy management and load balancing applications

Current Sensors Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm electrical ratings and package configuration. Ensure compatibility with downstream signal processing equipment requiring a 0–5 VDC input range. Confirm that the split-core aperture matches the conductor diameter of the target application to maintain measurement accuracy and physical fit.

Current Sensors Selection Notes

Select this component when a non-invasive method for measuring alternating current is required in industrial environments. The 50A rating defines the maximum continuous current capacity. The 0–5 VDC output interface simplifies integration with standard PLCs or data acquisition systems. Consider the split-core form factor if retrofitting existing installations where opening the main conductor is not feasible.

Current Sensors Part Context

This model belongs to the CR4210S series of AC current sensors from CR Magnetics Inc. The series is designed for broad electrical system monitoring. Variants within the series typically differ by current rating, such as 70A or 200A models, while maintaining similar functional architectures. This specific part represents the 50A capacity option within the split-core transformer family.

Current Sensors Replacement Considerations

Direct substitutes may include other CR4210S variants with different current ratings, such as the CR4210S-70 or CR4210S-200, provided the system current requirements align. Cross-model comparisons should verify output voltage ranges and physical dimensions to ensure mechanical and electrical compatibility.
