CR4470-25

Current Sensors Overview

The CR4470-25 is a solid core, average RMS AC current transducer from the CR4400 series by CR Magnetics Inc. It features a 3-element transformer design with bidirectional sensing capability for AC currents up to 25A. The device operates within a frequency range of 50Hz to 400Hz and requires a 24V DC supply with a maximum current consumption of 110mA. It provides a 0-5V DC output signal, suitable for loads greater than or equal to 2k ohms. The unit is housed in a module package designed for DIN rail or panel mounting, ensuring reliable performance in industrial environments.

Current Sensors Feature Summary

• Solid core transformer construction for robust AC current measurement
• Bidirectional sensing capability for accurate positive and negative cycle detection
• Integrated conditioning circuitry providing a standardized voltage output

Current Sensors Applications

• Industrial power monitoring systems requiring RMS current data
• Motor control applications for phase current feedback
• Energy management meters and power quality analyzers

Current Sensors Procurement Notes

Verify that the specific order suffix matches the required input current rating, as the base model number indicates the series rather than the exact amperage. Confirm the supply voltage requirement aligns with the system's 24V DC availability. Ensure the output load impedance meets the minimum specification to maintain signal integrity. Check RoHS compliance status if environmental regulations apply to the final assembly.

Current Sensors Selection Notes

Select this component when an average RMS measurement of AC current is sufficient for the application. The 25A rating defines the maximum continuous input current; ensure operational currents remain within this limit. The 50Hz-400Hz frequency range suits standard power and variable frequency drive outputs. Consider the physical dimensions for DIN rail or panel integration during the mechanical design phase.

Current Sensors Part Context

This part belongs to the CR4400 series of current transducers, which are characterized by their solid core design and integrated signal conditioning. The series offers various input ranges, with the -25 suffix denoting the 25A variant. These transducers are engineered for high reliability in demanding industrial settings, providing isolated measurement solutions without the need for split-core installation.

Current Sensors Replacement Considerations

Direct replacements must match the 25A input range, 24V supply, and 0-5V output characteristics. Verify that alternative components support the same 50Hz-400Hz frequency band and bidirectional operation. Physical mounting compatibility, such as DIN rail or panel fit, should be confirmed before substitution.
