CSCA0300A000B15B01 Open-Loop Hall Effect Current Sensor For Frequency Converters Overcurrent Protection
Working Principle:
Based on the Hall effect principle, when current flows through the primary conductor, it generates a rotating magnetic field around the conductor. This magnetic field is collected by a magnetic core made of magnetosensitive material and concentrated in the air gap of the core. The Hall Effect Device (HED) is positioned in the air gap, and its output is proportional to the amplitude and phase of the primary current. After gain and offset calibration, the sensor provides a preset output sensitivity relative to the primary current.
Application Fields:
Suitable for frequency converters, overcurrent protection, Uninterruptible Power Supplies (UPS), telecommunication power supplies, current feedback control systems, robotics, and other fields.
