General Description

CZ-3701 is an open-type current sensor using Hall sensors, which outputs the analog voltage

proportional to the AC/DC current. Group III-V semiconductor thin film is used as the Hall sensor, which enables the high-accuracy and high-speed current sensing. Coreless ultra-small surface mount package realizes the space-saving. Also, the low primary conductor resistance suppresses heat generation to achieve the 60Arms continuous current. Existing coreless current sensors have an accuracy disadvantage from degradations caused by a disturbed magnetic field. The CZ-370x series has a built-in stray magnetic field reduction function to suppress this effect. The CZ-370x series is also UL 61800-5-1 safety compliant, which is an excellent fit for industrial AC drives, servo motors, etc. The CZ-370x series has a large variety of linear measurement ranges, from ±5.3A (CZ-3700), to ±180A, (CZ-3706). This enables the designer to use the same board design across different products and helps the user to expand the options to different current ratings.
