CR4470-30

Current Sensors Overview

The CR4470-30 is a three-channel RMS AC current transducer from the CR4400 series, manufactured by CR Magnetics Inc. It features a solid core transformer design with conditioning for bidirectional sensing up to 30A per channel. The device provides a ratiometric DC output of 0V to 5V proportional to the average RMS input AC current. Key electrical parameters include an accuracy of ±0.5%, a supply voltage of 24V, and a maximum supply current of 110mA. It operates within a frequency range of 50Hz to 400Hz and has a response time of 250ms. The unit supports DIN rail or panel mounting and functions within a temperature range of 0°C to 60°C.

Current Sensors Procurement Notes

Verify that the specific part number matches the required sensing current rating of 30A and the three-channel configuration. Confirm compatibility with the 24V DC supply requirement and the 0V to 5V output interface. Ensure the installation environment falls within the specified operating temperature range of 0°C to 60°C. Check for RoHS3 compliance if environmental regulations apply to your project.

Current Sensors Selection Notes

Select this model when precise measurement of AC current up to 30A is required across multiple phases. The ±0.5% accuracy makes it suitable for applications demanding high fidelity in current monitoring. Consider the 50Hz to 400Hz frequency range to ensure compatibility with standard industrial power frequencies. The modular package allows for flexible integration into existing DIN rail or panel setups.

Current Sensors Part Context

This component belongs to the CR4400 series of current transducers and transmitters designed by CR Magnetics Inc. The series is engineered to produce accurate DC signals corresponding to AC current inputs. The CR4470-30 specifically addresses higher current requirements compared to lower-rated variants in the same family, maintaining consistent output characteristics and form factor.

Current Sensors Replacement Considerations

Direct substitutes within the CR4400 series include models with different current ratings such as CR4470-5 or CR4470-15, provided the application current does not exceed their limits. Verify that any replacement maintains the three-channel architecture and 0V to 5V output specification to ensure circuit compatibility.
