Current Sensors Procurement Notes

Verify the specific suffix 'S0E' against official LEM documentation to confirm mechanical mounting style and connector type. Ensure the supply voltage range aligns with system requirements. Cross-reference the accuracy and linearity specifications with the latest datasheet revision to guarantee compliance with application tolerances before procurement.

Current Sensors Selection Notes

Select this model when a 700 A nominal current rating is required for three-phase sensing. Consider the 40 kHz bandwidth and 6µs response time for high-frequency switching applications. Evaluate the mechanical fit for busbar mounting versus module integration. Compare against other HAH3DR variants if different current ratings or mounting configurations are needed.

Current Sensors Part Context

The HAH3DR series comprises tri-phase current sensors designed for xEV traction inverters. These sensors measure magnetic fields generated by primary currents in busbars. The series includes variants for different current ratings and mounting options, such as S07/SPx for module integration and S0x for busbar mounting. The HAH3DR 700-S0E is part of this family, offering high accuracy and low offset.

Current Sensors Replacement Considerations

Check LEM documentation for direct substitutes like HAH3DR 600-S0E or HAH3DR 800-S0E if current rating adjustments are acceptable. Verify mechanical compatibility and pinout definitions for any alternative models. Ensure that performance parameters such as bandwidth and accuracy meet the original design requirements.
