Introduction

CZ-3A04 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 50 A rms continuous current. Existing coreless current sensors have an accuracy disadvantage from degradations caused by a disturbed magnetic field. The CZ-3A0x series has a built-in stray magnetic field reduction function to suppress this effect. The CZ-3A0x series also has dual overcurrent detection function. The CZ-3A0x series is UL 61800-5-1 safety compliant, which is an excellent fit for industrial AC drives, servo motors, etc. The CZ-3A0x series is also an excellent fit to input the sensor signal into a 3.3V AD converter. The CZ-3A0x series has a large variety of linear measurement ranges, from ±12.9 A (CZ-3A01), to ±129.1 A (CZ-3A07). This enables designers to use the same board design across different current rating products.
