CR4110-75

Current Sensors Overview

The CR4110-75 is a True RMS AC current transducer from the CR4100 series, manufactured by CR Magnetics Inc. Designed for precise measurement of non-sinusoidal waveforms, this device features a single-element split-core design with a 0.79-inch window and supports an input range of 0.5 to 600 A AC. It provides proportional voltage outputs of 0–5 VDC or 0–10 VDC, powered by a 24 VDC supply with a maximum consumption of 25 mA. The unit offers ±0.5% accuracy across a frequency range of 20 Hz to 5 kHz, with a 250 ms response time. Operating bidirectionally within a temperature range of 0°C to 60°C, it mounts on 35 mm DIN rails or panels.

Current Sensors Feature Summary

• True RMS measurement capability ensures high precision for chopped wave and phase-fired control systems
• Single-element split-core design allows for easy installation around conductors up to 0.79 inches
• Bidirectional operation supports accurate monitoring of alternating current flow in both directions

Current Sensors Applications

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

Current Sensors Procurement Notes

Verify that the specific ordering suffix matches the required output voltage range (0-5 VDC or 0-10 VDC) and input current rating. Confirm whether the standard model includes UL recognition or if a split-core variant is needed for your installation requirements. Ensure the 24 VDC power supply specifications align with your system's electrical constraints before finalizing the order.

Current Sensors Selection Notes

Select the CR4110-75 when accurate measurement of distorted AC waveforms is critical, such as in phase-controlled heating applications. Choose this model over standard average-responding transducers if harmonic distortion or non-sinusoidal shapes are present. Consider the split-core configuration for retrofitting existing busbars without disconnecting power lines.
