CR4180-0.5

Current Sensors Overview

The CR4180-0.5 is a True RMS AC current transducer manufactured by CR Magnetics Inc., designed for precise measurement in phase-fired control systems. It features a triple-pass-through split-core design with three sensing elements, supporting an input range of 0.5A to 30AAC. The device provides a 4mA to 20mA DC output signal and operates on a 24V power supply. Key electrical specifications include a frequency response of 20Hz to 5kHz, ±0.5% basic accuracy, and a 250ms response time. It is rated for operation between 0°C and +60°C.

Current Sensors Feature Summary

• True RMS calibration ensures accurate measurement of chopped waves and non-sinusoidal AC currents
• Triple-pass-through split-core construction allows for easy installation around conductors without disconnection
• Bidirectional module design supports detection of current flow in both directions
• Integrated conditioning circuitry delivers a standardized 4-20mA output signal

Current Sensors Applications

• Phase-fired controlled heating systems
• Quickly varying motor load monitoring
• Industrial power quality analysis
• AC current monitoring in distribution panels

Current Sensors Procurement Notes

Verify the specific suffix matches the required input range and output configuration. Confirm that the split-core window dimensions align with the conductor size. Ensure the application environment stays within the specified temperature range. Check for UL 61010B-1 recognition if safety compliance is mandatory for the installation site.

Current Sensors Selection Notes

Select this model when high precision is required for non-linear AC waveforms typical in industrial controls. The triple-element design offers higher capacity than single or dual-channel variants. Consider the DIN rail or panel mount options based on enclosure constraints. Verify that the 24VDC power supply is available at the installation point.

Current Sensors Part Context

This component belongs to the CR4100 Series of True RMS Current Transducers. The series includes single, double, and triple element variants with different input ranges. The CR4180 specifically denotes the three-element configuration. Suffixes indicate input range and output type variations within the product line.

Current Sensors Replacement Considerations

Direct substitutes may include other CR4180 variants with different input ranges, such as CR4180-5 or CR4180-15, provided the current rating matches the application needs. Cross-brand replacements require matching True RMS capability, 4-20mA output, and split-core form factor.
