Closed loop - Magnetic Balance Hall Current Sensor - Brand [Weikewei]

Closed loop Hall current sensor基于磁平衡式霍爾原理設計當，原邊電流IP 產生的磁通通過高品質磁芯集中在 磁路中，hall sensor 固定在氣隙中檢測磁通，通過繞在磁芯上的多匝線圈輸出反向的補償電流，用于抵消原 邊IP 產生的磁通，使得磁路中磁通始終保持為零。經過特殊電路的處理傳，感器的輸出端能夠輸出精確反 映原邊電流的電流變化。

Closed loop typeThe Hall current sensor has the following technical specifications:

Auxiliary power supply: ± 15V range

Response time: ≤ 1us

Bandwidth: 100kHz

Imbalance current: 0.1mA

Output load: Depending on different auxiliary power sources, input signals, and output signals

Input overload capacity: Input range can be restored to normal operation by doubling the maximum value

Voltage withstand: 3.5kV/50Hz/1min

霍爾電流傳感器It has many advantages such as short response time and high operating frequency, so it can be widely used in variable frequency speed regulation devices, inverter devices, UPS power supplies, photovoltaic power generation, communication rooms, CNC machine tools, microcomputer monitoring systems, power grid monitoring systems, and various fields that require isolation and detection of current.
