Close Loop current hall sensor

Application:

Close loop hall current sensors is a new generation of current sensor which applies hall effect principle, can measure direct 

current, alternating current, pulse and current of various irregular wave forms in electrical isolation conditions.Higher accuracy and linearity, short responding time and wide frequency band make it widely used in current monitoring devices, high current 

protection and other fields. 

Features:

The product has many other advantages: firm structure, low power consumption, small size, light 

weight, long lifetime, easy installation, vibration resistance, water vapor proof and dust proof, which assure convenient and 

reliable usage. And users can define the rated primary current and secondary rated output based on actual demand.

Working Principle

The magnetic field produced by primary current Ip is balanced with 

the magnetic field produced by secondary coil current. The hall unit and auxiliary circuit produce secondary magnetic compensation current that can accurately response the primary current.

Functions:

Wide frequency band   No insertion loss

Excellent linearity   Quick response time

Good overall accuracy   Low temperature drift
