Current Sensors Procurement Notes

Verify the specific ordering suffix SP10 against official LEM documentation to ensure correct pinout and packaging configuration. Confirm that the application environment remains within the stated -40°C to 125°C operating temperature range. Ensure supply voltage stays strictly between 4.5 Vdc and 5.5 Vdc to maintain ±1% accuracy. Check datasheet for jumper temperature limitations not exceeding 120 °C.

Current Sensors Selection Notes

Select this component when precise measurement of bidirectional current flow up to 300 A is required in a unidirectional module format. The low supply current of 25 mA and wide operating temperature range make it suitable for various industrial environments. Ensure the system can accommodate the 2.5 µs response time and voltage output interface.
