CR4180-15

Current Sensors Overview

The CR4180-15 is a three-element True RMS AC current transducer designed for non-sinusoidal waveforms. It features a 15A input range with bidirectional capability and a triple pass-through window configuration. The device provides an analog output signal, typically scaled to standard industrial ranges such as 0-5V or 4-20mA, powered by a 24V DC supply. It offers high precision suitable for phase-fired control systems and chopped wave drivers, ensuring accurate measurement of harmonic currents and quickly varying motor loads in complex electrical environments.

Current Sensors Feature Summary

• True RMS measurement capability for accurate reading of non-sinusoidal AC waveforms
• Triple pass-through design allowing simultaneous monitoring of three conductors

• High precision construction optimized for phase-fired and chopped wave applications

Current Sensors Applications

• Phase-fired controlled heating systems
• Quickly varying motor load monitoring
• Chopped waveform driver analysis
• Harmonic current detection in power distribution

Current Sensors Procurement Notes

Verify the specific output signal type required for your system integration, as the CR4180 series supports multiple scaling options including voltage and current outputs. Confirm that the 24V DC power supply specification aligns with your existing infrastructure. Ensure the triple-pass-through physical dimensions fit within your panel or DIN rail mounting constraints. Cross-reference the datasheet for exact accuracy ratings under your specific operating temperature conditions to guarantee measurement integrity.

Current Sensors Selection Notes

Select this model when precise measurement of distorted AC waveforms is critical, particularly in industrial controls where standard average-responding sensors fail. The three-element architecture is essential for applications requiring simultaneous monitoring of multiple phases or conductors through a single unit. Consider the bidirectional feature if reverse current flow must be detected. This component is ideal for replacing older transducers in systems undergoing upgrades to handle modern variable frequency drives or solid-state switching loads.

Current Sensors Part Context

The CR4180-15 belongs to the CR Magnetics CR4100 Series of True RMS Current Transducers. This family is engineered for professional energy monitoring and industrial automation tasks. Unlike single-element variants, the CR4180 series accommodates three-phase or multi-conductor setups. The series is recognized by regulatory agencies including UL and CSA, meeting international safety standards for industrial equipment used in demanding electrical environments.

Current Sensors Replacement Considerations

Direct substitutes include other models within the CR4180 series with different current ratings, such as the CR4180-5 or CR4180-25, depending on the required amperage range. For two-element requirements, the CR4170 series may serve as a functional alternative. Verify that any replacement maintains the same True RMS technology and output signal specifications to ensure compatibility with existing control systems.
