CR4420S-0.5

Current Sensors Overview

The CR4420S-0.5 is a single-channel AC current sensor manufactured by CR Magnetics Inc., designed for industrial monitoring applications. It features a split-core transformer design with bidirectional polarity and module packaging. The device operates within a frequency range of 50Hz to 400kHz, detecting currents up to 0.5A. It provides a calibrated DC output proportional to the AC input, powered by a maximum supply current of 45mA at 24V. Key electrical parameters include ±0.5% accuracy, a 250ms response time, and an operating temperature range of 0°C to 60°C.

• Features a split-core transformer design allowing for non-intrusive installation on busbars or cables.
• Supports bidirectional current measurement capabilities for comprehensive monitoring.
• Designed for DIN rail mounting in demanding industrial environments.

Current Sensors Applications

• Industrial equipment current monitoring
• Power distribution system analysis
• Energy management systems
• Motor control circuit supervision

Current Sensors Procurement Notes

Verify the specific output signal type and sensitivity configuration required for your application against the official datasheet specifications. Confirm that the split-core aperture matches the physical dimensions of the conductor or busbar being monitored. Ensure the power supply voltage and current limits align with the 24V supply and 45mA maximum consumption requirements documented for this component.

Current Sensors Selection Notes

Select this model when precise measurement of low-level AC currents up to 0.5A is required in industrial settings. Consider the split-core form factor if retrofitting existing installations without breaking the primary circuit is necessary. Evaluate the frequency response range to ensure compatibility with the system's operating frequencies, noting the specified upper limit of 400kHz.

Current Sensors Part Context

This component belongs to the CR4420S series of average RMS current transducers from CR Magnetics Inc. The series is engineered to deliver accurate DC outputs proportional to AC inputs. These sensors are typically housed in modules suitable for DIN rail or panel installation, providing robust performance for continuous industrial operation.

Current Sensors Replacement Considerations

Direct substitutes within the same series include models such as CR4420S-5 or CR4420S-20, which offer different current detection ranges but share similar architectural characteristics. Verify that any replacement part maintains the required output signal type and mounting configuration before integration.
