CR4480-5

Current Sensors Overview

The CR4480-5 is a 3-channel RMS AC current transducer manufactured by CR Magnetics Inc. It utilizes an adjustable transformer with conditioning for bidirectional measurement of alternating currents up to 5A. The device provides a ratiometric output signal, specifically 4mA to 20mA, proportional to the input current. It operates on a 24V supply and maintains an accuracy of ±0.5%. The sensor supports frequencies between 50Hz and 400Hz, features a response time of 250ms, and functions within a temperature range of 0°C to 60°C.

Current Sensors Feature Summary

• Provides calibrated DC output proportional to AC current input using transformer technology with integrated conditioning
• Supports bidirectional current measurement across three independent channels
• Delivers standard industrial ratiometric current output signals for direct integration into monitoring systems

Current Sensors Applications

• Industrial power distribution monitoring
• Motor control and protection circuits
• Energy management systems requiring RMS current data

Current Sensors Procurement Notes

Verify that the specific order suffix matches the required output signal type, as the CR4480 series includes variants with different output configurations such as voltage or current modes. Confirm the primary current rating aligns with the application load, as the base model designation indicates a 5A capacity. Ensure the supply voltage requirements match the system infrastructure before procurement.

Current Sensors Selection Notes

Select this component when precise RMS measurement of bidirectional AC currents is required in industrial environments. The 3-channel configuration allows simultaneous monitoring of multiple phases or lines. Consider the 4mA-20mA output compatibility with existing PLC or SCADA inputs. Verify frequency range requirements against the 50Hz-400Hz operational specification.
