Littelfuse CF1S010N & CF1S011N Current Sensors

Littelfuse CF1S010N and CF1S011N Current Sensors offer a very low offset current measurement through a CAN communication interface. The devices use Fluxgate technology, providing high sensing accuracy. The structure supplies galvanic separation between the primary circuit (HV) and the secondary circuit (12V CF1S010N or 24V CF1S011N).    

The Littelfuse CF1S010N and CF1S011N Current Sensors are built for energy storage, Battery Management Systems, battery junction boxes,
battery disconnect units, and uninterruptible power supplies.
