CR4111-50

Current Sensors Overview

The CR4111-50 is a True RMS AC current transducer manufactured by CR Magnetics Inc. It features a single solid core design with a 0.79-inch window, supporting an input range of up to 50A AC. The device operates within a frequency range of 20 Hz to 5 kHz and requires a 24 VDC power supply with +/-10% tolerance. It provides a 0-10 VDC output signal and draws a maximum supply current of 25mA. The unit supports bidirectional polarization and offers a response time of 250ms. Operating temperatures range from 0°C to 60°C.

Current Sensors Procurement Notes

Verify the specific part number suffix matches the required input range and output specifications. Confirm that the operating temperature range and power supply voltage align with your system environment. Ensure the mounting type (DIN rail or panel) fits your installation constraints. Cross-reference the datasheet for pin configuration and wiring details before integration.

Current Sensors Selection Notes

Select this component when True RMS accuracy is critical for non-sinusoidal AC waveforms. The 50A input range suits moderate load applications. Consider the 20 Hz to 5 kHz frequency bandwidth against your system's operational frequencies. Evaluate the 250ms response time against real-time control requirements. Compare physical dimensions and mounting options with available space in the enclosure.

Current Sensors Part Context

This model belongs to the CR4111 series of True RMS AC current transducers from CR Magnetics Inc. The series includes variants with different input ranges, such as the CR4111-20 and CR4111-30. These devices share similar architectural features, including solid core designs and dual mounting capabilities, but differ in their specific current handling capacities and calibration parameters.

Current Sensors Replacement Considerations

Direct substitutes include other models within the CR4111 series, such as the CR4111-20 or CR4111-30, provided the input range difference is acceptable. Verify compatibility with existing wiring and mounting hardware. No alternative manufacturers are explicitly confirmed in public documentation.
