CR4150-10

Current Sensors Overview

The CR4150-10 is a True RMS AC current transducer from the CR Magnetics CR4100 series, designed for precise measurement of non-sinusoidal waveforms. It features a split-core design with a 0.26-inch window and supports dual-channel operation. The device provides a 0 V to 5 V DC output ratio signal, powered by 24 VDC with a maximum supply current of 75 mA. It offers ±0.5% accuracy across a frequency range of 20 Hz to 5 kHz, with a response time of 250 ms. Operating within 0°C to 60°C, it mounts on DIN rails or panels.

Current Sensors Feature Summary

• True RMS measurement capability for accurate reading of chopped waves and phase-fired control systems
• Split-core construction allowing installation without breaking the primary circuit
• Dual-channel module format with printed connection diagrams on the case
• Bidirectional polarity detection for comprehensive current monitoring

Current Sensors Applications

• Phase-fired controlled heaters
• Quickly varying motor loads
• Chopped wave form drivers
• Harmonic current analysis

Current Sensors Procurement Notes

Verify the specific input range suffix (e.g., -10) against official CR Magnetics documentation to confirm the exact amperage rating, as model numbers in this series denote different window sizes and ranges. Ensure the required output type matches the available options for the CR4150 variant. Confirm regulatory compliance requirements such as UL 61010B-1 recognition if applicable to the installation environment. Check for any specific mounting hardware requirements for DIN rail or panel installation.

Current Sensors Selection Notes

Select the CR4150-10 when high precision is required for distorted AC waveforms where standard transducers fail. Choose this model over the CR4160 series if a voltage output (0-5V) is preferred over current output (4-20mA). Consider the 0.26-inch window size for conductor fitment. Verify that the 24 VDC power supply aligns with existing system infrastructure. Evaluate the need for bidirectional sensing capabilities before finalizing the choice.

Current Sensors Part Context

The CR4150-10 belongs to the CR4100 Series of True RMS Current Transducers manufactured by CR Magnetics. This series is engineered for applications involving complex AC current waveforms. The CR4150 variant specifically utilizes a two-element split-core design with a smaller window compared to the single-element CR4110/CR4120 models. It is part of a broader family including CR4160, CR4170, and CR4180 models, differentiated by input ranges and output types.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult CR Magnetics directly for cross-reference information or equivalent models within the CR4100 series that match the required input range and output specifications.
