The CZ-3A03 is an open-type current sensor utilizing Hall effect technology to provide an analog voltage output proportional to AC/DC current. It features a high-accuracy, high-speed sensing capability due to its Group III-V semiconductor thin film Hall sensor. The coreless, ultra-small surface mount package ensures space-saving design, while low primary conductor resistance minimizes heat generation, enabling a continuous current of 50Arms. This series incorporates a built-in stray magnetic field reduction function to mitigate accuracy degradation from disturbed magnetic fields and offers a dual overcurrent detection function with adjustable thresholds. The CZ-3A03 is UL 61800-5-1 safety compliant, making it ideal for industrial AC drives, servo motors, and applications requiring signal input to a 3.3V ADC. It offers a wide range of linear measurement capabilities, allowing for consistent board design across different current ratings.
