LEM Flux Gate Current Sensor

LEM Flux Gate Current Sensor


This LEM CANbus current sensor is the ideal sensor for hybrid and electric vehicle battery packs that require very high accuracy current measurement. Fully galvanically isolated, using fluxgate technology, the CAB measures up to +/-400/500A with less that 0.1 % error, and no offset. It operates with 12V battery voltage and communicates through the automotive industry standard CAN bus. Dimensioned for installation within the battery pack and rated for operation in the temperature range from -40 °C to +105°C. Automotive applications : Very high accuracy current monitoring for hybrid and/or electric vehicle battery packs
