Current Sensors Procurement Notes

Verify that the specific part number matches the required 75A rating and 4-20mA output configuration. Confirm that the operating environment temperature remains within the specified 0°C to 60°C range. Ensure the application frequency falls between 50Hz and 400Hz. Check for RoHS compliance status if environmental regulations apply to the project.

Current Sensors Selection Notes

Select this component when measuring AC currents up to 75A using a non-invasive solid-core method. It is suitable for applications requiring a standard 4-20mA interface. Consider the ±10% accuracy limit against system requirements. Verify that the 24VDC supply voltage aligns with available power rails in the installation environment.
