CR4450-15

Current Sensors Overview

The CR4450-15 is a two-element current transducer designed for AC input currents ranging from 0 to 15 A. It provides a proportional DC output signal, specifically 0 to 5 VDC, which corresponds to the average RMS input AC current. The device operates on a 24 V power supply and features a bidirectional measurement capability with an accuracy of ±0.5%. It supports a frequency range of 50 Hz to 400 kHz and has a response time of 250 ms. The unit consumes a maximum of 75 mA during operation and functions within a temperature range of 0°C to 60°C. Designed for multi-point sensing, it offers high precision in a compact module format suitable for DIN rail or panel mounting.

Current Sensors Procurement Notes

Verify the specific model suffix to confirm the exact current rating, as the CR4450 series includes variants such as -15, -40, and -50. Ensure the application requires AC current measurement compatible with the 50Hz to 400kHz frequency range. Confirm that the 24V DC power supply requirement aligns with the system design. Check for split-core availability if non-intrusive installation is needed by appending 'S' to the prefix. Validate regulatory compliance requirements against UL 61010B-1 and IEC 61010-1 standards for the intended environment.

Current Sensors Selection Notes

Select this component when precise average RMS AC current measurement is required for industrial control applications. The 0-5 VDC output interface ensures compatibility with most commercially available instrumentation. Consider the physical window size and mounting type based on the installation constraints. The bidirectional feature allows for monitoring current flow in both directions, which is essential for certain power distribution scenarios. Evaluate the accuracy requirements against the ±0.5% specification to ensure it meets the system's tolerance levels.

Current Sensors Part Context

The CR4450-15 belongs to the CR Magnetics Current Transducers and Transmitters series, which are engineered for value and performance in industrial settings. This series is designed to produce DC output signals proportional to AC input currents, facilitating easy integration into monitoring systems. The product line emphasizes high accuracy and versatile mounting options, catering to diverse industrial needs. It is part of a broader family that includes various current ratings and output configurations, supporting comprehensive sensor solutions.

Current Sensors Replacement Considerations

Direct substitutes within the CR4450 series include models with different current ratings, such as CR4450-40 or CR4450-50, if the application current exceeds 15A. For split-core requirements, append 'S' to the base model number (e.g., CR4450S-15). Cross-series comparisons should consider the CR4410 or CR4420 series for single-element applications, though output ranges and window sizes may differ. Verify that any replacement maintains the 24V power supply and 0-5VDC output specifications.
