Description

Even in a coreless architecture, CZ-380x series has a disturbing magnetic field suppression function on chip. This sensor measures the magnetic flux created by the current, but it will not sense the magnetic flux which wraps the whole sensor such as the disturbing magnetic field. It is a current sensor that can take a more accurate measurement under large disturbing magnetic field. Because of the small package, it is very suitable for applications that have many current paths in a limited area such as the distribution board and the three-phase inverter circuit. AKM can provide three types of different current sensing range products.

CQ-320x series is a coreless current sensor in small size package with high galvanic isolation, especially designed for sensing the current range from 10.1 to 35A in 3.3V operation. This low-voltage operating current sensor is suitable for air conditioning and solar power conditioner applications. Five types of different current sensing range products are available. Furthermore, these products are planned to obtain certification from IEC/UL, so they can be used for industrial application.
