Closed-Loop Hall Current Sensor

Closed-Loop Hall Current Sensor

The Closed-Loop Hall Current Sensor operates on the Magnetic Balance Principle: the magnetic field from the primary current is mutually balanced by the field from the secondary coil current. The Hall element and auxiliary circuitry generate a secondary compensation current which accurately reflects the primary current change. It offers fast response time, high accuracy, excellent linearity, low temperature drift, and wide frequency bandwidth. Widely used in variable frequency drives (VFD), servo systems, motor control drives, railway traction, overcurrent protection, and various monitoring applications.
