Closed-loop Hall Current Sens
Closed- loop Hall current sensors, manufactured using the Hall magnetic compensation principle, are used to measure 50A~300A DC, AC and pulse currents. The primary side input current IM 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.
