HSN Family

High compactness current sensor with integrated busbar +/- 1000A. Suitable for high power battery management system and motor control applications

HSN - Automotive current sensors

The HSN current sensors family is purpose-built for electronically measuring DC, AC, or pulsed currents in high-power, low-voltage automotive applications, ensuring galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit).

One of the distinctive features of the HSN family is its ability to provide various current measuring ranges within the same housing.

Within this family, the HSNBV Series is specifically tailored for Battery Management Systems (BMS), while the HSNDR Series is designed to meet the requirements of automotive motor control applications.

These automotive current sensors of the HSN family operate based on the open-loop Hall effect principle, ensuring precise and reliable current measurements in automotive applications.
