Product Overview

The CZ-3A07 is an open-type current sensor utilizing advanced Hall sensor technology for high-accuracy and high-speed AC/DC current measurement. Its coreless, ultra-small surface mount package offers space-saving benefits, while a low primary conductor resistance enables a 50Arms continuous current rating with suppressed heat generation. Designed with a built-in stray magnetic field reduction function and dual overcurrent detection, the CZ-3A0x series ensures reliable performance even in disturbed magnetic environments. It is UL 61800-5-1 safety compliant and ideal for industrial applications such as AC drives, servo motors, UPS, and power conditioners, as well as for interfacing with 3.3V AD converters. The CZ-3A0x series offers a range of linear measurement capabilities, allowing for consistent board designs across different current ratings.
