ASR-04-1200A:333MV

Current Sensors Overview

The Aim Dynamics ASR-04-1200A:333MV is a three-channel Rogowski coil current sensor designed for AC measurement applications. It features a sensing capacity of 1200A per channel and provides a ratiometric output voltage ranging from 0V to 0.333V. The device operates within a supply voltage range of 9V to 36V and maintains an accuracy of ±1% across all channels. It functions effectively in operating temperatures between -20°C and typical industrial limits, supporting integration into various control systems requiring precise phase monitoring.

Current Sensors Feature Summary

• Three-phase Rogowski coil architecture for simultaneous multi-channel AC current sensing
• High precision performance with ±1% accuracy across all channels
• Ratiometric analog output signal compatible with standard data acquisition systems

Current Sensors Applications

• Monitoring unbalanced loads where phase imbalances exceed 15%
• Industrial control system integration
• Electrical panel and device monitoring

Current Sensors Procurement Notes

Verify the specific part number suffix to ensure correct output scaling and sensitivity configuration. Confirm that the application environment falls within the specified temperature range and supply voltage limits. Ensure compatibility with downstream signal conditioning circuits accepting the 0V to 0.333V output range before finalizing procurement.

Current Sensors Selection Notes

Select this component when high-accuracy three-phase measurement is required for currents up to 1200A. The wide supply voltage range facilitates integration into diverse power architectures. Consider the ratiometric output nature for noise immunity requirements in noisy industrial environments compared to fixed voltage outputs.

Current Sensors Part Context

This model belongs to the ASR series of Super Rogowski Coils with Integrator by Aim Dynamics. These sensors transform AC inputs into proportional voltage outputs. The ASR-04 variant specifically addresses three-phase applications, distinguishing it from single or dual-channel models within the broader product family.

Current Sensors Replacement Considerations

The ASR-04-100A:333MV serves as a functional substitute if the application current does not exceed 100A. Verify that the reduced sensing range meets the maximum expected load requirements while maintaining identical output characteristics and interface specifications.
