SMALL AND HIGH ACCURACY CORELESS CURRENT SENSOR
30. January 2019 | Planegg
World's smallest housing, high accuracy, high signal-to-noise ratio and the world's fastest response time
The market has been recently demanding smaller sized systems, dustproof, and waterproof structures. Small bodies, lower heat generation and high temperature operation range is required for current sensors. The CZ-381x series has a miniaturized body while maintaining a low-heat generation characteristic, supporting up to 125°C operation temperature. It is suitable for systems having difficulty in heat suppressing design and applications that use large current, e.g. AC Motors, DC Motors, UPS’s, Power Conditioners and Air Conditioners.
The CZ-381x series supports up to 125°C operation temperature by suppressing heat generation with an originally developed AKM package. This enables 40 Arms continuous current, making the CZ-381x usable even in the current range where conventional current sensors with a core are required. Therefore, downsizing for existing systems is possible.
This current sensor series has a highly accurate coreless current sensor with 0.7% F.S. (Typical). This will contribute to improving system efficiency and precise control in a wide range of applications.
The CZ-381x series achieves this size using a coreless structure AKM’s developed original package. The package size is 11.5 x 8.3 x 2.0 (mm), which is about 1/20 of the volume of conventional products.
