• Measurement of distorted AC waveforms
• Busbar integration in electrical distribution panels

Current Sensors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct configuration. Confirm that the required split-core version matches the application's physical constraints. Cross-reference the datasheet for any recent product change notices or environmental compliance updates prior to finalizing procurement orders.

Current Sensors Selection Notes

Select this component when unidirectional current measurement up to 1000 A is required. The true RMS output makes it suitable for applications involving distorted waveforms. Ensure the system can accommodate the split core mechanical design and verify that the 1% accuracy meets the precision requirements of the target circuit.

Current Sensors Part Context

This part belongs to the AHR series of AC/DC current transducers from LEM. It is designed for high-current applications where true RMS measurement is critical. The split core architecture distinguishes it from solid-core variants, offering easier installation around existing conductors without breaking the circuit.
