The Redarc Tow Pro is a Brake Control Unit designed to suit most common trailer braking applications, requiring minimal dash space and being simple to install and operate. Tow Pro offers selectable automatic (inertia sensing) or user controlled trailer braking modes allowing the user to choose the braking style depending on the road or terrain conditions, vehicle type or driver preference. The unit is able to operate both electric and electric/hydraulic trailer brakes without manual selection and will operate from either 12 or 24V vehicle systems without the need for extra components or wiring. The Self Learning automatic system incorporated into the EBRH-ACC has the ability to replicate the voltage control of a proportional brake control unit. This means a slow reduction in vehicle forward momentum can deliver smoother trailer stopping power, when a sudden stop will bring on maximum power to trailer brakes momentarily. The unit can be mounted in any direction as long as the installation is secure and the main unit cannot move or change orientation.
