CR4150-25

Current Sensors Overview

The CR4150-25 is a two-channel True RMS AC current transducer manufactured by CR Magnetics Inc. Designed for non-sinusoidal waveform measurement, it features a dual pass-through module construction with a 25A detection range per channel. The device provides a 0V to 5V ratio output and operates on a 24V power supply with a maximum current draw of 75mA. It supports frequencies from 20Hz to 5kHz with ±0.5% accuracy and a 250ms response time. The unit is polarized bidirectionally and supports DIN rail or panel mounting within an operating temperature range of 0°C to 60°C.

Current Sensors Feature Summary

• True RMS measurement capability for accurate analysis of chopped wave and phase-fired control systems
• Dual pass-through module design accommodating two independent AC current channels
• Bidirectional polarization allowing detection of current flow in both directions

Current Sensors Applications

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

Current Sensors Procurement Notes

Verify the specific model suffix against official CR Magnetics documentation to confirm the exact output signal type and input range configuration. Ensure that the required 24V DC power supply meets the maximum current consumption specifications. Confirm that the installation environment falls within the specified operating temperature limits and that the mounting method aligns with the dual pass-through module dimensions.

Current Sensors Selection Notes

Select this component when precise measurement of distorted AC waveforms is required rather than standard average-responding sensors. The dual-channel architecture is suitable for applications needing simultaneous monitoring of two separate circuits. Consider the 0V to 5V output compatibility with downstream PLC or data acquisition systems. Verify that the 25A rating matches the peak load requirements of the monitored equipment.

Current Sensors Part Context

This part belongs to the CR4100 Series of True RMS Current Transducers and Transmitters. The series is engineered for industrial environments where AC current waveforms are not purely sinusoidal. It offers higher precision compared to conventional transducers, making it ideal for complex control systems involving phase firing or harmonic distortion.

Current Sensors Replacement Considerations

Consult official manufacturer substitution lists for verified equivalents. Generic replacements may lack True RMS accuracy or dual-channel functionality. Ensure any substitute maintains the same 24V power requirement and 0V to 5V output interface.
