Hall effect current sensor for leakage current detection

 

P/N: LO-HALL-CT0100

 

Introduction

 

Closed-loop sensors measure AC and DC currents and provide electrical isolation. They offer fast response, high linearity, and low emperature drift. The current output of the closed-loop sensor is relatively immune to electrical noise. The Closed- Loop sensor is sometimes called a'Zero-Flux'sensor because its Hall-Effect sensor feeds back an opposing current into a secondary coil, wound on the magnetic core to zero the flux produced in the magnetic core by the primary current. Closed-loop sensors are often the sensor of choice when high accuracy is essential.
