CR4410S-150

Current Sensors Overview

The CR4410S-150 is an AC current transducer from the CR4400 series by CR Magnetics Inc., designed for average RMS measurement. It features a split-core design with a 150A input range and supports bidirectional current detection. The device provides a proportional DC output signal, typically interfacing via RS485 or analog outputs like 0-5VDC, depending on configuration. It operates on a 24V supply with a maximum current draw of 30mA. Key electrical specifications include a frequency response of 50Hz to 400Hz, an accuracy of ±0.5%, and a response time of 250ms. The unit is housed in a module package suitable for DIN rail or panel mounting.

Current Sensors Procurement Notes

Verify the specific output type required, as the CR4410S-150 may be available with different interface options such as RS485 or analog voltage/current signals. Confirm that the split-core variant (indicated by the 'S' suffix) matches the physical conductor size of your application. Ensure the operating temperature range of 0°C to 60°C aligns with your environmental conditions. Check for RoHS compliance status if required by your project specifications.

Current Sensors Selection Notes

Select this model when a non-invasive measurement solution is needed for high-current AC applications up to 150A. The split-core architecture is ideal for retrofits where opening the cable loop is impractical. Consider the ±0.5% accuracy rating for precision monitoring tasks. Ensure the power supply voltage matches the 24V requirement. Compare against other series members if lower current ranges or different channel counts are necessary for the system design.

Current Sensors Part Context

This component belongs to the CR4400 series of current transducers and transmitters. The series is characterized by low-cost DIN rail or panel mount designs suitable for commercial instrumentation. Other models in the family include variants with different input ranges and channel counts, such as the CR4410S-100 or CR4470-5, offering flexibility for various sensing requirements within the same product line.

Current Sensors Replacement Considerations

Direct substitutes within the CR4400 series include the CR4410S-100 for lower current ranges or the CR4410S-5 for smaller conductors. If a fixed core is acceptable, the non-split versions like CR4410-150 may serve as alternatives. Verify that any replacement maintains the required split-core window size and output signal compatibility.
