    LEM HAH1BVS/04 Open-Loop Hall Effect Current Sensor

     

    LEM HAH1BVS/04 Product Overview

    The HAH1BVS/04 is an open-loop Hall effect current transducer from LEM's HAH1BVS series, designed for the electronic measurement of DC, AC, and pulsed currents in high-power and low-voltage automotive applications. The series features galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit) .

    The HAH1BV and HAH1DR families are specifically engineered for high-power and low-voltage applications, with the BV series dedicated to battery monitoring applications and the DR series designed for motor drive applications. These families offer different peak current choices in the same housing for flexible platform-based selection .
