CR9580-50

Current Sensors Overview

The CR9580-50 is a self-powered AC current sensor manufactured by CR Magnetics Inc. It features a split core design with a hinged ring, allowing for non-intrusive installation around conductors. The device operates within a frequency range of 50 Hz to 400 Hz and supports an input current range of 0 to 50 A AC. It provides a ratiometric output signal ranging from 0 V to 5 V DC, proportional to the sensed current. The sensor exhibits an accuracy of ±0.5% and requires no external power supply, deriving energy directly from the measured magnetic field.

Current Sensors Feature Summary

• Self-powered operation eliminates need for external voltage supply
• Split core construction enables easy installation without circuit interruption
• Ratiometric 0-5 VDC output ensures compatibility with standard data acquisition systems

Current Sensors Applications

• Monitoring AC current in industrial power distribution systems
• Energy metering applications requiring isolated current measurement
• Power quality analysis in frequency ranges up to 400 Hz

Current Sensors Procurement Notes

Verify that the specific part number matches the required current rating and output specifications. Confirm the physical dimensions of the split core aperture match the conductor size. Ensure the operating frequency range aligns with the application requirements. Check for any mounting hardware included or required separately. Validate the accuracy class against system tolerance needs.

Current Sensors Selection Notes

Select this model when a self-powered solution is preferred to simplify wiring. Consider the 50 A input range for moderate load monitoring tasks. The split core design is suitable for retrofits where breaking the circuit is not feasible. Verify that the 0-5 V output interface matches the receiving equipment inputs. Ensure the frequency range covers the fundamental and harmonic content of the signal.

Current Sensors Part Context

This component belongs to the CR9580 series of average RMS self-powered AC current sensors. The series offers various current ratings, including 10 A, 20 A, and 50 A options. All models share similar operational principles, utilizing transformer-based sensing with conditioning circuits. The series is designed for cost-effective current monitoring in AC environments.

Current Sensors Replacement Considerations

Direct substitutes include other CR9580 series variants with different current ratings if the 50 A limit is insufficient. Models such as CR9580-20 or CR9580-10 may be considered for lower current applications. Cross-brand replacements require matching the self-powered nature, split core design, and 0-5 V output characteristics.
