CR4120-150

Current Sensors Overview

The CR4120-150 is a single-phase True RMS AC current transducer designed for non-sinusoidal waveform applications. It features a 150A sensing range with ±0.5% accuracy and a frequency response of 20Hz to 5kHz. The device provides a ratiometric 4mA to 20mA output signal and operates on 24V DC power. Constructed as a dual-channel module, it supports both DIN rail and panel mounting configurations.

Current Sensors Feature Summary

• True RMS measurement capability ensures precision for chopped wave and phase-fired control systems
• Ratiometric 4mA to 20mA output signal for reliable industrial integration
• Dual-channel module design supporting flexible DIN rail or panel installation

Current Sensors Applications

• Phase fired controlled heaters
• Quickly varying motor loads
• Chopped wave form drivers
• Harmonic current monitoring

Current Sensors Procurement Notes

Verify the specific ordering suffix against official CR Magnetics documentation to confirm output type and mounting style. Ensure the input current rating matches the 150A requirement. Confirm that the 24V DC power supply aligns with system voltage standards. Check for any regulatory compliance markings such as UL or CSA if required by local safety codes.

Current Sensors Selection Notes

Select this model when high accuracy is required for distorted AC waveforms rather than pure sine waves. The 150A range suits medium-to-high current industrial circuits. Consider the 4-20mA output compatibility with existing PLC or SCADA inputs. Verify that the operating temperature range of 0°C to 60°C meets environmental conditions.

Current Sensors Part Context

This component belongs to the CR4100 Series of True RMS Current Transducers from CR Magnetics. The series is engineered for professional energy monitoring where standard transducers fail due to harmonic distortion. It complements other models like the CR4110 and CR4150 within the same product family.

Current Sensors Replacement Considerations

Cross-reference part numbers such as CR4110-20 for lower current ranges. Verify that substitute models maintain True RMS functionality and compatible output signals. Ensure physical dimensions and mounting styles match existing infrastructure constraints.
