CR4470-20

Current Sensors Overview

The CR4470-20 is a solid-core AC current transducer manufactured by CR Magnetics Inc. designed for measuring alternating current up to 20A RMS. It features a modular package suitable for DIN rail or panel mounting. The device provides a calibrated analog output proportional to the input current, typically available in 0-5VDC, 0-10VDC, or 4-20mA variants. Operating within a frequency range of 50Hz to 400Hz, it ensures accurate monitoring in industrial power systems.

Current Sensors Feature Summary

• Solid-core design eliminates the need for splitting the primary conductor during installation
• Modular construction supports flexible DIN rail and panel mounting configurations
• Calibrated analog output signals compatible with standard data acquisition systems

Current Sensors Applications

• Industrial motor control cabinet monitoring
• Power distribution system current measurement
• Energy management and metering applications

Current Sensors Procurement Notes

Verify the specific output signal type required for your application, as the CR4470 series offers multiple options including voltage and current outputs. Confirm that the 20A rating aligns with your maximum expected load. Ensure compatibility with the operating temperature range and supply voltage specifications before integration into the final system design.

Current Sensors Selection Notes

Select this model when a non-intrusive current measurement solution is needed for circuits carrying up to 20A RMS. The solid-core architecture simplifies wiring compared to split-core alternatives. Consider the environmental conditions and mounting constraints to ensure the modular form factor fits the designated enclosure space effectively.

Current Sensors Part Context

This component belongs to the CR4400 series of RMS AC current transducers from CR Magnetics. The series provides a complete line of sensors for electrical instrumentation, covering various current ranges up to 150A. The CR4470-20 specifically addresses mid-range current monitoring needs within this broader product family.

Current Sensors Replacement Considerations

Direct substitutes include other models within the CR4470 series with different current ratings, such as the CR4470-5 or CR4470-20, depending on the specific amperage requirement. Cross-referencing with other CR Magnetics solid-core transducers is recommended if interface or mounting differences exist.
