Product Description
Product Overview
The CSNE151-100 is a high-precision closed-loop current sensor designed for demanding automotive, robotics, and industrial applications. Utilizing magnetic compensation technology, it delivers exceptional accuracy and fast response times for current monitoring and control systems.
Working Principle
This sensor operates on the magnetic compensation principle using zero-flux methodology. It continuously maintains zero magnetic flux in the sensor core, with the balancing current proportional to the primary current. The closed-loop output current reflects the primary current scaled by the winding turns ratio and can be converted to voltage via external resistors.
