HAH2 Family
High performance dual phase current sensor +/- 500A. Suitable for high power motor control and inverter applications, with high integration
HAH2 - Automotive current sensors
The HAH2 family is a dual-phase sensor for DC, AC, or pulsed currents measurement in high power and low voltage automotive applications. It offers a galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit).
The HAH2 family gives you a choice of having different current measuring ranges in the same housing (from ±100 up to ±500 A).
The HAH2 automotive current sensors are designed on the open loop hall effect technology.
