The CZ-3A01 is an open-type, coreless current sensor utilizing advanced Group III-V semiconductor thin film Hall sensors for high-accuracy and high-speed AC/DC current sensing. Its ultra-small surface mount package and low primary conductor resistance (0.27m Typ.) minimize heat generation, enabling a 50Arms continuous current rating. The sensor features a built-in stray magnetic field reduction function to mitigate accuracy degradation from disturbed magnetic fields and a dual overcurrent detection function with adjustable thresholds. Compliant with UL 61800-5-1 safety standards and certified with UL-1577 and IEC/UL62368-1, the CZ-3A01 is ideal for industrial applications like AC drives, servo motors, and UPS systems, and is suitable for inputting sensor signals into 3.3V AD converters. It offers a wide range of linear measurement options, starting from 12.9A for the CZ-3A01 model, allowing for consistent board designs across different current ratings.
