CR4211S-20

Current Sensors Overview

The CR4211S-20 is a self-powered AC current transducer from the CR4211 Series, manufactured by CR Magnetics Inc. It utilizes a split-core design to measure alternating current without requiring an external power supply for operation. The device is calibrated to provide a 0-10 VDC output signal that is proportional to the sensed AC current. This specific model supports a measurement range of 0-20 Amps and operates within a frequency range of 50-400 Hz. It incorporates a very low-noise instrumentation amplifier to ensure high measurement accuracy, making it suitable for applications where precise sensor signal conditioning is critical.

Current Sensors Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to confirm specifications. Ensure the application environment falls within the operational temperature and frequency limits defined in the datasheet. Confirm availability status as distribution channels may vary. Cross-reference the output signal type with system requirements prior to integration.

Current Sensors Selection Notes

Select this component when a self-powered solution is required for AC current measurement up to 20 Amps. Consider the split-core form factor for ease of installation on existing conductors. Evaluate the 0-10 VDC output compatibility with downstream data acquisition or control systems. Verify that the operating frequency range of 50-400 Hz aligns with the target application's electrical characteristics.

Current Sensors Part Context

The CR4211S-20 belongs to the CR4211 Series of self-powered AC current transducers. This series is characterized by its ability to generate a proportional DC voltage output directly from the sensed current. The S-series designation typically indicates a split-core configuration, distinguishing it from solid-core variants. These devices are designed for applications prioritizing measurement accuracy and simplified wiring due to their self-powered nature.

Current Sensors Replacement Considerations

Consult official manufacturer documentation for direct substitutes. The CR4211S-2 is a related model within the same series but features a different current rating (0-2A). Ensure any replacement matches the 0-10 VDC output specification and split-core design. Verify that alternative parts support the required 20A range and 50-400 Hz frequency operation.
