CSCA-A Series
Hall-Effect Based Open-Loop
Current Sensors
DESCRIPTION
The CSCA-A Series of open-loop current sensors are based

concentrated in the gap in this core. The HED is located in this

on the principles of the Hall-effect wherein a Hall-effect device

core gap. Therefore, the HED output is directly proportional to

(HED) produces an output voltage linearly related to the

the amplitude and phase of the primary current.

The HED output is trimmed for gain and offset calibration such
