It senses AC current passing through a conductor and provides a scaled, isolated output for measurement circuits.

No, it only works with alternating current (AC). For DC current sensing, use a Hall-effect sensor.

You need to place a burden resistor across the secondary winding. The voltage across this resistor is proportional to the primary current.

The core may saturate, leading to inaccurate readings or signal clipping. Extended overcurrent can also degrade the core magnetics.

Yes, but ensure proper calibration and thermal design, especially for inverter feedback loops or variable current loads.
