CR4110-5

Overview

The CR4110-5 is a True RMS AC current transducer from the CR4100 series, designed for precise measurement of alternating currents. It features a single-channel bidirectional configuration with a solid core input capable of handling up to 5A AC. The device provides a ratiometric output voltage ranging from 0V to 5VDC, ensuring compatibility with standard data acquisition systems. Key electrical specifications include an accuracy of ±0.5%, a frequency response spanning 20Hz to 5kHz, and a maximum supply current of 25mA at 24V. The unit operates within a temperature range of 0°C to 60°C and offers a fast response time of 250ms.

Feature Summary

• True RMS AC current measurement capability for accurate waveform analysis
• Bidirectional sensing allows detection of current flow in both directions
• Ratiometric output signal scales linearly with input excitation
• Solid core design eliminates need for circuit interruption during installation

Applications

• Industrial power monitoring systems requiring high accuracy
• Energy management and smart metering applications
• Motor control and drive feedback loops
• Electrical safety testing equipment

Procurement Notes

Verify that the specific order matches the CR4110-5 designation to ensure the 5A rating and 0-5V output are correct. Confirm that the application environment stays within the specified 0°C to 60°C operating temperature range. Ensure the load impedance meets the minimum requirement of 2kΩ for proper signal integrity. Check that the supply voltage is stable at 24V DC to maintain the stated ±0.5% accuracy. Validate that the frequency of the measured current falls between 20Hz and 5kHz.

Selection Notes

Select this model when a bidirectional AC current sensor with True RMS accuracy is required. The 5A input range suits moderate current applications without needing external shunts. The 0-5V output is ideal for direct connection to PLCs or microcontrollers. Consider the 20Hz lower frequency limit if measuring very low-frequency signals. The DIN rail or panel mount options provide flexible integration into existing control panels.

Part Context

This component belongs to the CR4100 series of transformer-based current sensors manufactured by CR Magnetics Inc. The series includes variants with different current ratings and output voltages, such as the CR4111-0.5 and CR4110-30. These devices share common architectural features like solid core inputs and ratiometric outputs but differ in their specific measurement ranges and calibration parameters.

Replacement Considerations

Direct substitutes within the same series include models with adjusted current ratings like the CR4110-20 or CR4110-30, provided the input current range aligns with the application needs. Other series members may offer different output voltages, such as the 0-10V variant found in the CR4111 series. Ensure any replacement maintains the bidirectional functionality and True RMS characteristic.
