ASR-400MV-11/B

Current Sensors Overview

The ASR-400MV-11/B is a high-input Rogowski coil current sensor manufactured by Aim Dynamics, designed for AC measurement applications. It features a primary input range of 500 mA to 50 kA and provides an output of 400 mV per kA at 60 Hz. The device has a 11-inch diameter and supports a peak continuous current of 50,000 amperes. It operates with a working voltage of 1000 V CAT III or 600 V, ensuring safety in industrial environments. The sensor exhibits a positioning error better than 1% of the reading and maintains a coil resistance between 300 and 2000 Ω.

Current Sensors Feature Summary

• Utilizes Rogowski coil technology for non-intrusive AC current sensing
• High sensitivity output of 400 mV per kA for precise signal acquisition
• Robust insulation rating supporting 1000 V CAT III operational safety
• Low positioning error ensuring accurate measurements regardless of conductor placement

Current Sensors Applications

• Monitoring large-scale industrial AC systems
• High-current power distribution network analysis
• Electrical testing equipment integration

Current Sensors Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest documentation to confirm mechanical dimensions and connector types. Ensure the application environment does not exceed the 1000 V CAT III working voltage limit. Cross-reference the 11-inch inner diameter requirement with existing busbar or cable configurations to guarantee proper fitment during installation.

Current Sensors Selection Notes

Select this model when measuring currents up to 50 kA with high accuracy requirements. The 11-inch diameter accommodates larger conductors compared to smaller variants. Consider the 400 mV/kA output scaling for downstream signal conditioning compatibility. Verify that the AC frequency matches the 60 Hz calibration point for optimal performance.

Current Sensors Part Context

This component belongs to the ASR-400MV series of high-input Rogowski coils from Aim Dynamics. The series offers various diameters to suit different conductor sizes while maintaining consistent electrical characteristics. The ASR-400MV-11/B specifically addresses applications requiring measurement of very high currents within a large physical aperture.

Current Sensors Replacement Considerations

Other models in the ASR-400MV series, such as the ASR-400MV-07/G or ASR-400MV-04/R, offer similar electrical performance but with different 7-inch or 4-inch diameters respectively. Choose these alternatives only if the physical space constraints require a smaller coil aperture.
