EOL
Description
CQ209A is an open-type current sensor using a Hall sensor which outputs the analog voltage proportional to the AC / DC current. Quantum well ultra-thin film InAs (Indium Arsenide) is used as the Hall sensor, which enables the high-accuracy and high-speed current sensing. Simple AI-Shell package with the Hall sensor, magnetic core, and primary conductor realizes the space-saving and high reliability.
Key Features
-
High precision and high speed. Employs a highly sensitive quantum well structure InAs Hall element, and is characterized by the ability to detect both DC and AC with high accuracy and high speed.
Applications
-
Inverter control in air-conditioners, industrial equipments, power conditioners, etc.
