AKM expanded the line-up of Coreless Current sensors: CQ-330x series launched.


[Product name]

CQ-330B, CQ-330E, CQ-330F, CQ-330G, CQ-330H
[Application]

Industrial/commercial inverter, Motor controller, Power conditioner, UPS
[Description] AKM developed and launched unidirectional current sensors in addition to the bidirectional type. The unidirectional sensor is suitable for the DC current measurement where accuracy is required such as solar photovoltaics. AKM offers multiple unidirectional current sensors with different current sensing ranges.
CQ330x series are coreless current sensors in small size package with high galvanic isolation, especially designed for sensing the current range from 4.5A to 42A. By packaging the high-sensitivity and the fast-response Hall effect sensor IC along with the primary current conductor in small VSOP package, CQ330x series provide good performance in small sized inverter application. Furthermore, these products have obtained certification from IEC/UL, so they can be used for industrial application.
