CR4110S-150

Current Sensors Overview

The CR4110S-150 is a True RMS AC current transducer from the CR4100 series, designed for precise measurement of non-sinusoidal waveforms. It features a split-core design with a 0.79-inch window and supports an input range up to 600A AC. The device provides a 0-10V DC output ratio signal, operates on 24V DC power with a maximum supply current of 25mA, and achieves ±0.5% accuracy. It functions within a frequency range of 20Hz to 5kHz, has a response time of 250ms, and is rated for bidirectional current sensing in an operating temperature range of 0°C to 60°C.

Current Sensors Feature Summary

• True RMS measurement capability ensures high precision for chopped wave and phase-fired control systems where waveforms are not purely sinusoidal.
• Split-core construction allows for easy installation around existing conductors without circuit interruption.
• Bidirectional sensing polarity enables accurate monitoring of alternating current flow in both directions.

Current Sensors Applications

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

Current Sensors Procurement Notes

Verify that the specific suffix 'S' confirms the split-core configuration required for your installation geometry. Confirm the output voltage range matches your control system inputs, as this model specifies a 0-10V DC ratio output. Ensure the primary conductor fits within the 0.79-inch window aperture. Check regulatory compliance markings against local safety standards for industrial equipment.

Current Sensors Selection Notes

Select this model when measuring AC currents exceeding standard transformer limits or requiring true RMS accuracy for distorted waveforms. The split-core variant is essential for retrofitting existing busbars or cables. Consider the 0-10V output compatibility with PLCs or data acquisition systems. Verify that the 24V DC power supply aligns with available panel power rails.

Current Sensors Part Context

This component belongs to the CR4100 series of True RMS Current Transducers manufactured by CR Magnetics. The series includes single-element models like the CR4110 and dual-element models like the CR4150. The CR4110S-150 specifically utilizes the single-element architecture with a larger window size compared to the two-element variants, supporting higher current ranges up to 600A AC.

Current Sensors Replacement Considerations

Direct substitutes include other CR4110 series models with compatible output signals. Models such as CR4110-150 offer similar functionality but may differ in core type. External 5 Amp secondary current transformers can be used to extend measurement ranges if necessary. Verify mechanical mounting dimensions match DIN rail or panel requirements.
