CRD4150-15

Current Sensors Overview

The CRD4150-15 is a two-element True RMS AC current transducer manufactured by CR Magnetics Inc. It features a dual-channel design with a 15A AC input range and provides a proportional 0V to 5V DC output signal. The device operates on a 24V DC power supply with a maximum current consumption of 75mA. It supports frequencies from 20Hz to 5kHz and maintains an accuracy of ±0.5%. The unit is bidirectional, has a response time of 250ms, and functions within a temperature range of 0°C to 60°C. It is designed for DIN rail or panel mounting in a double-through module package.

Current Sensors Feature Summary

• True RMS measurement capability ensures accurate readings for non-sinusoidal waveforms such as chopped waves and phase-fired control signals.
• Dual-channel architecture allows simultaneous monitoring of two separate AC current paths within a single compact module.
• Bidirectional sensing detects current flow in both directions, providing comprehensive data for complex industrial load analysis.

Current Sensors Applications

• Phase-fired controlled heater systems
• Quickly varying motor loads
• Chopped waveform drivers

Current Sensors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure the correct output type and window configuration. Confirm that the required input range matches the 15A specification. Check regulatory compliance markings such as UL 61010B-1 and IEC 61010-1 if required for your installation environment. Ensure the power supply voltage aligns with the 24V DC requirement.

Current Sensors Selection Notes

Select this model when precise measurement of distorted AC currents is necessary, as standard average-sensing transducers may provide inaccurate results. The dual-channel feature is suitable for applications requiring simultaneous monitoring of two circuits without additional hardware. Consider the 20Hz to 5kHz frequency range to ensure compatibility with the system's operating speed. Verify that the physical mounting constraints allow for DIN rail or panel installation.

Current Sensors Part Context

This component belongs to the CR4100 Series of True RMS Current Transducers and Transmitters. The series is engineered for environments where AC current waveforms are not purely sinusoidal. It offers higher precision than other transducers and is ideal for use with external current transformers to extend ranges. The series includes single-element and two-element variants with various input ranges and output options.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult the manufacturer for direct replacements or cross-reference models within the same CR4100 series family that match the specific channel count and input range requirements.
