CR4170-0.5

Current Sensors Overview

The CR4170-0.5 is a True RMS AC current transducer from the CR4170 series, designed for measuring alternating currents up to 0.5A. It features a triple-pass-through transformer design with three channels and provides a 0V to 5V output signal. The device operates on a 24V supply with a maximum current draw of 60mA. Key specifications include ±0.5% accuracy, a frequency range of 20Hz to 4kHz, and a response time of 250ms. It supports bidirectional sensing and functions within an operating temperature range of 0°C to +60°C.

Current Sensors Feature Summary

• Triple-pass-through transformer architecture ensures high precision for non-sinusoidal waveforms
• True RMS calibration capability for accurate measurement of complex AC signals
• Bidirectional sensing functionality allows detection of current flow in both directions
• Modular design supports DIN rail or panel mounting for flexible integration

Current Sensors Applications

• Power quality monitoring systems requiring precise RMS current data
• Industrial motor control applications with variable frequency drives
• Energy management systems tracking low-current consumption loads
• Electrical testing equipment validating AC circuit performance

Current Sensors Procurement Notes

Verify that the specific part number CR4170-0.5 matches the required 0.5A rating, as the CR4170 series offers multiple current ranges. Confirm the 24V DC supply requirement aligns with your system power architecture. Ensure the 0V-5V analog output interface is compatible with your data acquisition hardware. Check RoHS3 compliance status if environmental regulations apply to your deployment.

Current Sensors Selection Notes

Select this model when measuring AC currents at or below 0.5A with high fidelity. The True RMS feature is essential for non-linear loads where peak measurements are insufficient. Consider the 250ms response time against your system's dynamic requirements. The three-channel configuration may offer redundancy or multi-phase monitoring capabilities depending on wiring complexity.

Current Sensors Part Context

This component belongs to the CR4170 series of True RMS AC current transducers by CR Magnetics Inc. The series utilizes a three-element transformer design to handle distorted waveforms accurately. Unlike standard average-responding sensors, these devices provide true root-mean-square values, making them suitable for modern electronic loads that generate harmonic distortions.

Current Sensors Replacement Considerations

Direct substitutes within the same series include CR4170-0.25 for lower current ranges or CR4170-1 for higher capacity needs. Cross-series replacement requires verifying matching output voltage ranges and supply voltages. Ensure the replacement maintains the 20Hz-4kHz frequency response if operating near the lower limits of the original specification.
