The Bendix+ EC-30 is an electronic ABS (antilock braking system) controller. It is the base component in a family of ABS assemblies for heavy and medium duty buses, trucks and tractors utilizing pneumatic braking systems. The ABS function of the EC-30 controller is designed to optimize slip on all vehicle wheels. The EC-30 controller provides the vehicle with improved stability and steerability during braking. The EC-30 controller will also reduce vehicle stopping distance on most surfaces. In addition to the ABS function, the EC-30 controller can be confi gured to provide an ATC (automatic traction control) feature. Bendix ATC can improve vehicle traction during acceleration on adverse road conditions. ATC can utilize engine torque limiting and/or differential braking to improve vehicle traction.
