When it comes to high-precision current measurement in industrial and automotive applications, engineers often face challenges with accuracy, stability, and electromagnetic interference. The LEM HASS500-S current sensor stands out as a reliable solution for these issues. This Hall-effect-based sensor offers a nominal primary current range of ±500A, making it ideal for applications like electric vehicle inverters, battery management systems, and motor control units.\u00a0For instance, in an EV application, the HASS500-S can provide real-time monitoring of the traction inverter’s current with minimal phase shift and excellent linearity over a wide temperature range (-40°C to +125°C). According to LEM‘s datasheet, the sensor achieves an impressive accuracy of ±0.6% at 25°C, which is critical for optimizing energy efficiency and ensuring safe operation.\
