描述 Description

CSCA-A Series Hall-effect based, open-loop current sensor, Molex-type connector, 400 A RMS nominal, ±900 A range.CSCA-A Series inductive analog current sensors are based on Hall-effect technology. A Hall-effect device (HED) produces an output voltage linearly related to the amplitudeand phase of a magnetic field applied to it. Current flowing through a primary conductor generates a rotating magnetic field around the conductor.This field is collected by a core of magnetically sensitive material and is concentrated in the core's gap where the HED is located. Therefore, the HED outputis directly proportional to the amplitude and phase of the primary current. The HED output is trimmed for gain and offset calibration so that the CSCA-A Seriessensor provides a predefined output sensitivity versus primary current.
