Current Sensors Procurement Notes

Verify the specific suffix SP1 against official LEM documentation to confirm pinout configuration and mechanical dimensions. Ensure the selected variant matches the required supply voltage and output signal specifications for the target application. Cross-reference the manufacturer datasheet for any recent updates to certification standards or recommended operating conditions before finalizing procurement.

Current Sensors Selection Notes

Select this component when a robust, isolated current sensing solution is required for AC or DC currents up to 350 A. Consider the 466.7 mA output signal level for compatibility with downstream ADCs or amplifiers. Evaluate the thermal performance and insulation voltage ratings against the specific environmental and electrical stress conditions of the end-use equipment to ensure long-term reliability.
