HAH2 Series Automotive Current Sensors
LEM high-performance dual-phase current sensors are suitable for high-power motor control and inverter applications with high integration
LEM HAH2 series is a dual-phase sensor for DC, AC, or pulsed current measurement in high-power and low-voltage automotive applications. It offers a galvanic separation between the primary circuit and the secondary circuit. These sensors offer the choice of having different current measuring ranges in the same housing, from ±100 up to ±500 A. The HAH2 sensors are designed with open-loop Hall effect technology and are engineered for demanding high-power motor control and inverter applications.
