    LEM HAH1BVS/06 Open-Loop Hall Effect Current Sensor

     

    LEM HAH1BVS/06 Product Overview

    The HAH1BVS/06 is an open-loop Hall effect current transducer from LEM's HAH1BVS series. The series is designed for the electronic measurement of DC, AC, and pulsed currents in high-power and low-voltage automotive applications, with 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. The BV series is dedicated to battery monitoring applications, while the DR series is designed for motor drive applications. These families offer different peak current choices in the same housing for flexible platform-based selection, making the series ideal for electric and hybrid electric vehicle Battery Management Systems.

     

    LEM HAH1BVS/06 Key Technical Specifications

    Based on the HAH1BVS/D24 variant which shares the same series architecture, the HAH1BVS/06 is confirmed to have the following core specifications:
