Contributing to the improvement of system safety! Coreless current sensor with built-in high-speed, high-precision overcurrent detection function.
CZ3Axx is a magnetic coreless current sensor with built-in Hall elements and overcurrent detection functionality. It achieves a high-speed response of 1μs and high precision of 0.3% F.S., enabling the detection of various fault modes such as ground faults and arm short circuits, contributing to improved system safety. Additionally, through its unique packaging technology, it realizes a low primary conductor resistance of "0.27mΩ" and high insulation with a creepage/clearance distance of ≧8mm. This significantly reduces heat generation during current application compared to shunt resistors, and eliminates the need for a primary side power supply or amplifier for insulation, allowing overcurrent detection with just the IC. Therefore, it can be placed in limited spaces on a circuit board. *For more details, please refer to the PDF document or feel free to contact us.
