CR4480-25

Current Sensors Overview

The CR4480-25 is a solid-core, average RMS AC current transducer manufactured by CR Magnetics Inc. It features a 3-channel transformer design with conditioning for bidirectional measurement. The device supports an input range of 0 to 25A AC and operates within a frequency range of 50Hz to 400Hz. It provides a calibrated DC output proportional to the AC input, specifically 0V to 5VDC across a load of 2k ohms or greater. Powered by 24VDC (±10%), it ensures high accuracy with a basic precision of ±0.5%. The unit includes 2500VDC insulation voltage and is suitable for DIN rail or panel mounting.

Current Sensors Procurement Notes

Verify that the specific order matches the CR4480-25 part number to ensure the correct 25A rating and 3-channel configuration. Confirm that the application environment falls within the operational specifications regarding frequency and voltage. Ensure proper handling procedures are followed during installation to maintain insulation integrity. Check for any required accessories for DIN rail or panel mounting depending on the final assembly requirements.

Current Sensors Selection Notes

Select this model when a 25A AC current range is required with high accuracy. Consider the 50Hz to 400Hz frequency range for compatibility with standard power lines or variable frequency drives. The 0-5VDC output interface facilitates easy integration with PLCs and data acquisition systems. Verify that the 24VDC power supply is available and stable within the ±10% tolerance for reliable operation.

Current Sensors Part Context

This component belongs to the CR4480 Series of Average RMS Current Transducers from CR Magnetics Inc. The series is designed to provide accurate monitoring of AC currents in various industrial applications. The CR4480-25 specifically denotes the 25A input range variant within this family, sharing common design principles with other models like the CR4480-100 but differing in rated current capacity.

Current Sensors Replacement Considerations

Direct substitutes include other CR4480 series variants if different current ratings are needed, such as the CR4480-100 for higher capacity. Cross-model comparisons should be made with the CR4420S-25 to verify functional equivalence regarding channel count and output type. Always confirm pinout and mounting dimensions match before substitution.
