ASR-400MV-11/R

Current Sensors Overview

The ASR-400MV-11/R is a high-input Rogowski coil current sensor manufactured by Aim Dynamics. It features an 11-inch diameter aperture designed for measuring alternating current (AC) in industrial applications. The device supports a primary input range from 500 mA to 50 kA. At 60 Hz, the output signal is calibrated at 400 mV per kA of primary current. This configuration allows for precise monitoring of large-scale electrical systems without direct galvanic contact.

Current Sensors Feature Summary

• Highly linear output response across the dynamic range
• Completely shielded design to minimize external magnetic interference
• Capable of withstanding large overloads without damage
• Calibrated prior to delivery for accuracy

Current Sensors Applications

• Monitoring large-scale industrial AC systems
• High-current measurement in power distribution networks
• Testing and validation of heavy electrical equipment

Current Sensors Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure correct aperture size and output characteristics. Confirm RoHS compliance status and lead-free requirements if applicable to your assembly process. Cross-reference the part number with the latest datasheet to validate active product status and any recent specification updates before finalizing procurement orders.

Current Sensors Selection Notes

Select this model when an 11-inch internal diameter is required to accommodate large busbars or cable bundles. Ensure the application involves AC current measurements within the 500 mA to 50 kA range. Consider the 400 mV/kA output scaling factor for compatibility with downstream integrators or data acquisition systems. Verify that the shielding requirements align with the electromagnetic environment of the installation site.

Current Sensors Part Context

This component belongs to the ASR-400MV series of Rogowski coils from Aim Dynamics. Variants in this series differ primarily by aperture diameter, such as the 4-inch or 7-inch models. The 11-inch version is specifically engineered for larger conductors where standard sensors cannot fit. All units in this line share common features like high linearity and overload protection.

Current Sensors Replacement Considerations

Direct substitutes include other Aim Dynamics models within the ASR-400MV series, such as the ASR-400MV-11/B or ASR-400MV-11/G, provided the aperture diameter and output specifications match the original design requirements. Always verify mechanical dimensions and mounting interfaces before substitution.
