Brake Controllers
Electric brake controllers provide power to the magnets to actuate
the trailer brakes. Dexter Axle offers a state-of-the-art inertial
controller called the Predator Series™ DX2. This controller
features a patented pendulum design which senses the
deceleration of the towing vehicle and sends a proportional
voltage to the electric trailer brakes. Other features include a
visual gain setting for quick and easy adjustment and a digital
LED display to show the voltage output. A manual override sends
full voltage to the trailer brakes, regardless of gain setting, for
emergency conditions and also illuminates the brake lights to
warn of an impending stop.
Most electric brake controllers provide a modulation function that
varies the current to the electric brakes with the pressure on the
brake pedal or amount of deceleration of the tow vehicle.
Electronic or timing controllers do not provide proportional
modulation. These controllers tend to be inexpensive but not the
best choice for optimum braking. It is important that your brake
controller provide approximately 2 volts to the braking system
when the brake pedal is first depressed and gradually increases
the voltage to 12 volts as brake pedal pressure is increased. If
the controller "jumps" immediately to a high voltage output, even
during a gradual stop, then the electric brakes will always be fully
energized and will result in harsh brakes and potential wheel
lockup.
