5.1. Axustes axustables

The controller provides fully adjustable power and ramp time with a range of gain and load settings. These settings allow you to match the brake controller's performance to your specific vehicle-trailer configuration and towing conditions.

Configuración de ganancia: Adjusts the maximum braking power delivered to the trailer. Increase for heavier loads or more aggressive braking, decrease for lighter loads or less aggressive braking.
Configuración de carga: Fine-tunes the ramp-up speed of the trailer brakes.

5.2. Triple-Axis Motion Sensing

The integrated triple-axis, motion-sensing accelerometer ensures smooth, responsive stops. The third axis dynamically adjusts power when driving on uphill or downhill terrain, optimizing braking performance without manual intervention.
