APS3 Inverters
THE OPTIMAL FIT TO ALL VEHICLE TYPES
The 3rd generation Advanced Power Steering (APS) controller has been meticulously engineered to fulfill the requirements set forth by the European standards for functional safety. The APS directly interfaces a variety of steering input devices and motor types. It can function and operate in a stand-alone steering system, or as a part of an overall CAN open-based vehicle system. The product range covers a wide variety of vehicle applications including Class 1, 2, and 3 lift trucks.
