Closed-loop Hall Current Sensors
Closed-loop Hall current sensors, manufactured using the Hall magnetic compensation principle, are used to measure 2000A DC, AC and pulse currents. The primary side input current IN is electrically isolated from the secondary side output current IM and follows the input current linearly in a true manner.
Key Features
Application area

Various power supplies, welding machines, industrial automation control, electrical drives, frequency converters, motor servo, power systems, railroad systems, etc.
