ASR-400MV-07/B

Current Sensors Overview

The Aim Dynamics ASR-400MV-07/B is a Rogowski coil current sensor 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 operates within a frequency range of 40 Hz to 14 kHz, ensuring accurate data acquisition across wide dynamic ranges. Key performance specifications include a linearity of ±0.2% and an overall accuracy of ±0.5%. The sensor is self-powered and functions reliably in operating temperatures between -30°C and 80°C.

Current Sensors Feature Summary

• Highly linear output with ±0.2% linearity specification
• Completely shielded design to minimize external magnetic influence
• Resistant to damage from large overloads due to air-core construction
• Self-powered operation eliminating the need for external supply voltage

Current Sensors Applications

• AC current monitoring in industrial power systems
• Energy metering and power quality analysis
• Motor drive and variable frequency drive feedback loops
• Electrical testing equipment calibration

Current Sensors Procurement Notes

Verify that the specific suffix '07/B' matches the required connector type and cable length configuration. Confirm that the 400 mV/kA output scaling aligns with the input requirements of the downstream signal conditioning or data acquisition hardware. Ensure the operating temperature range of -30°C to 80°C meets the environmental conditions of the installation site. Cross-reference the 50 kA maximum sensing current against peak load expectations to prevent saturation during transient events.

Current Sensors Selection Notes

Select this model when high accuracy and wide bandwidth are critical for AC current measurements up to 50 kA. The Rogowski coil architecture offers flexibility in installation around busbars or cables without breaking the circuit. Consider the ±0.5% overall accuracy requirement against system tolerance levels. The self-powered nature simplifies wiring compared to active Hall-effect sensors, though it requires appropriate signal amplification for low-current signals below 1 kA.

Current Sensors Part Context

This component belongs to the ASR-400MV series of Rogowski coil sensors from Aim Dynamics. The series is characterized by its ability to measure high currents with minimal insertion loss and high safety margins. The ASR-400MV-07/B variant specifically denotes the standard configuration with defined output scaling and connector options. It serves as a non-invasive alternative to traditional CTs for dynamic AC current monitoring.
