• Bidirectional capability for both AC and DC current sensing
• Proportional output signal compatible with standard ADCs
• High isolation and immunity to electromagnetic interference

Current Sensors Applications

• xEV automotive traction inverters
• Motor control systems
• 800V three-phase power modules

Current Sensors Procurement Notes

Verify the specific suffix designation carefully, as the HAH3DR series includes variants such as S00, S03, and S0E which may differ in mechanical mounting or connector types. Confirm lifecycle status, as some sources indicate the S00 variant may be obsolete while newer versions are available. Ensure compatibility with the target inverter module's mechanical interface before procurement.

Current Sensors Selection Notes

Select this component when a compact solution for 700A nominal current is required in high-voltage environments. The device is suitable for designs needing fast response times and high bandwidth for motor control. Consider the mechanical integration options, as the series offers versions for direct module installation or busbar mounting with cable connectors.

Current Sensors Part Context

This part belongs to the LEM HAH3DR series, a family of current sensors specifically engineered for xEV automotive traction inverters. The series is characterized by its compact size, high accuracy, and mechanical compatibility with major power module manufacturers. It supports both IGBT and SiC technologies.

Current Sensors Replacement Considerations

Check for updated suffixes like HAH3DR 700-S03/SP4 or HAH3DR 700-S0E if the S00 version is unavailable. Verify that any substitute maintains the same 700A IPN and mechanical footprint to ensure seamless integration into existing inverter designs.
