Overview
The Honeywell CSNS300F-001 is a closed loop current sensor built on Hall effect and null balance (zero magnetic flux) principles. The sensor constantly controls magnetic flux in the core at zero, and measures primary current based on the feedback current required to balance that zero flux, multiplied by the primary-to-secondary winding ratio. This design delivers high precision and stability for AC, DC, and impulse current measurement in industrial automation, power distribution, and motor control applications.
