Closed-loop Hall Current Sensors
Closed-loop Hall current sensors, manufactured using the Hall magnetic compensation principle, are used to measure 2KA...6KA DC, AC and pulse currents. The primary input current IM is electrically isolated from the secondary output current IM and follows the input current linearly in a true manner.
Key Features
Application area

Various power supplies, industrial automation control, electric power systems, rectification systems, nuclear physics research and other industrial and scientific research technology fields.
