CR4211S-50

Current Sensors Overview

The CR4211S-50 is a self-powered AC current transducer manufactured by CR Magnetics Inc. It features a split-core design for non-intrusive installation on conductors carrying alternating current. The device provides an average RMS output voltage proportional to the input current, with an input range of 0-50 AAC and an output range of 0-5 VDC. It operates within a frequency band of 50-400 Hz and supports an output load of at least 1M ohm. Electrical isolation is rated at 2500 VDC. The unit functions without an external power supply, deriving energy from the sensed current, and operates reliably in temperatures ranging from 0°C to +60°C.

Current Sensors Procurement Notes

Verify that the specific part number matches the required current rating and output specification. Confirm that the application environment falls within the specified temperature range and frequency limits. Ensure that the conductor size accommodates the split-core aperture. Check for any specific mounting requirements or accessory needs for secure installation.

Current Sensors Selection Notes

Select this model when a non-invasive measurement solution is required for AC currents up to 50A. Consider the self-powered nature for applications where providing separate power is difficult. Evaluate the 0-5VDC output compatibility with downstream data acquisition systems. Assess the frequency response requirements against the 50-400Hz operational range.

Current Sensors Part Context

This component belongs to the CR4211S series of self-powered AC current transducers. The series offers various current ratings to suit different load capacities. All models share similar core technologies including split-core design and self-powering mechanisms. The -50 suffix specifically denotes the 50 Ampere input capacity variant within this product family.

Current Sensors Replacement Considerations

Direct substitutes may include other CR Magnetics models within the same series if current ratings differ. Cross-brand replacements require matching self-powered functionality, split-core geometry, and output signal characteristics. Verify isolation voltage and frequency response capabilities before substitution.
