The SCT103 AC Current Sensor is a non-invasive split-core current transformer designed to measure alternating current (AC) without cutting or disconnecting the electrical wire. Its clamp-style design allows easy installation around a single conductor, providing an isolated output signal proportional to the measured current. With a measurement range of up to 30A AC and a convenient 3.5mm audio-jack connector on common versions, the SCT103 is suitable for energy monitoring, power measurement, overcurrent detection, and microcontroller-based projects.
