Current Sensors Procurement Notes

Verify the specific ordering suffix matches the required output signal and voltage configuration. Confirm that the split core aperture size accommodates the target conductor diameter. Ensure the operating frequency range aligns with the application's electrical environment requirements before finalizing the purchase order.

Current Sensors Selection Notes

Select this model when high accuracy is required for complex AC waveforms rather than simple sinusoidal currents. The split core architecture facilitates retrofitting into existing panels. Consider the 4-20mA output compatibility with standard PLC or DCS input modules for seamless integration into control systems.
