Current Sensors Procurement Notes

Verify the specific suffix SP15 against official LEM documentation to confirm terminal type and mechanical dimensions. Ensure the required isolation voltage rating meets system safety standards. Confirm that the ±15 V supply requirement aligns with available control circuitry before procurement.

Current Sensors Selection Notes

Select this component when high-precision DC current measurement is required in space-constrained environments. The Fluxgate technology ensures stability over temperature variations. Verify that the Faston interface matches existing PCB layout requirements and that the 100 A primary rating covers the maximum expected load current.

Current Sensors Part Context

This model belongs to the LV series of closed-loop current sensors from LEM. These sensors are designed for industrial applications requiring accurate current feedback. The series typically integrates Hall or Fluxgate elements with signal processing electronics on a single board.

Current Sensors Replacement Considerations

Consult LEM official substitution guides for direct replacements. Generic equivalents may not match the Fluxgate 'C' performance characteristics or isolation ratings. Verify pinout compatibility if considering alternative models.
