CR9580-20-M

Current Sensors Overview

The CR9580-20-M is a split-core AC current sensor manufactured by CR Magnetics Inc. It features a hinged ring design with a 0.40-inch diameter, allowing for non-invasive installation around conductors without circuit interruption. The device is self-powered and provides a ratiometric output signal ranging from 0 V to 5 VDC, corresponding to an AC current range of 0 to 20 A in average-RMS form. It operates within a frequency band of 50 Hz to 400 Hz and supports bidirectional current measurement. The unit includes wire leads for connection and maintains an accuracy of ±0.5%.

Current Sensors Feature Summary

• Split-core hinged ring design enables non-invasive installation around existing busbars or cables
• Self-powered operation eliminates the need for external supply voltage
• Bidirectional sensing capability allows accurate measurement of current flow in both directions
• Provides a calibrated 0–5 VDC analog output representing average-RMS AC current values

Current Sensors Applications

• AC power monitoring systems requiring non-intrusive current measurement
• Industrial equipment where existing wiring must remain uninterrupted during sensor installation
• Energy management solutions utilizing average-RMS current data for load analysis
• Bidirectional power flow monitoring in renewable energy or battery storage interfaces

Current Sensors Procurement Notes

Verify that the specific suffix '-M' corresponds to the hinged ring configuration with wire leads as documented. Confirm the operating temperature range of -30°C to 60°C aligns with the intended environment. Ensure the frequency range of 50 Hz to 400 Hz matches the application's electrical characteristics. Cross-reference the 0.40-inch inner diameter with the conductor size to guarantee proper fit within the split core.

Current Sensors Selection Notes

Select this component when non-invasive installation is required for AC current monitoring up to 20 A. The self-powered nature simplifies system design by removing supply constraints. The bidirectional feature is essential for applications involving reverse power flow. The 0–5 VDC output is compatible with standard industrial data acquisition systems. Verify that the average-RMS output format meets the precision requirements of the downstream processing electronics.
