ASR-400MV-04/G

Current Sensors Overview

The ASR-400MV-04/G is a high-input Rogowski coil current sensor manufactured by Aim Dynamics. It features a 4-inch diameter input ring designed for measuring alternating current (AC) up to 50,000 amperes. The device provides a ratiometric output signal proportional to the measured current. Key electrical specifications include an accuracy of ±0.5% and linearity of ±0.2%. The operational frequency range spans from 40Hz to 14kHz. The unit is self-powered and operates within a temperature range of -30°C to 80°C.

Current Sensors Feature Summary

• Highly linear output with wide dynamic range
• Completely shielded construction
• Resistant to damage from large overloads
• Calibrated prior to delivery

Current Sensors Applications

• Power distribution systems
• High-current industrial applications
• Large-scale industrial AC system monitoring

Current Sensors Procurement Notes

Verify the specific suffix 'G' against the manufacturer's latest documentation to confirm mechanical dimensions and connector type. Ensure the required measurement range aligns with the 50kA capacity. Confirm that the self-powered nature of the Rogowski coil integrates correctly with the downstream integrator or data acquisition system in the target application design.

Current Sensors Selection Notes

Select this model when precise measurement of very high AC currents is required without direct electrical contact. The 4-inch aperture size dictates the cable or busbar thickness it can accommodate. Consider the frequency response limits if the application involves non-standard harmonic content. The self-powered design simplifies wiring but requires careful integration with signal conditioning electronics.

Current Sensors Part Context

This component belongs to the ASR-400MV series of high-input Rogowski coils from Aim Dynamics. Variants in this series differ primarily by the physical diameter of the sensing ring, such as the 7-inch ASR-400MV-07/G. All models share similar electrical performance characteristics regarding accuracy and linearity, tailored for heavy-duty industrial environments requiring robust current sensing solutions.

Current Sensors Replacement Considerations

Direct substitutes may include other Aim Dynamics models with different diameters, such as the ASR-400MV-07/G, provided the physical installation space allows for the larger ring. Cross-manufacturer replacements require verifying identical output characteristics, frequency response, and mounting constraints.
