Curt Trailer Brake Controller - Proportional Controller - C49UR Review


Jeff Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Curt Assure proportional trailer brake controller with the dynamic screen for one to four axle trailers. Now this brake controller will activate your trailers brakes in proportion to your vehicles braking action. It'll automatically adjust the trailers braking based on the deceleration of your tow vehicle, and it does activate immediately, there's no pausing like with a time delayed brake controller. This one has this nice large, high quality one and a half inch OLED screen. It displays full text readout.

And as you can see, the display can be tilted for different mounting options, either above or below the dash. The self leveling feature on this ensures that the brake controller will continue to function even as you drive up steep hills or through the mountains. Basically you just simply mount this in your cab at a vertical angle that is within 90 degrees, and the controller will level itself automatically. And then just make sure that the controller is also positioned so that the side to side angle is within plus or minus 20 degrees. This does offer nine sensitivity settings, boost settings, it'll let you adjust initial braking power and aggressiveness.

It does use a triple axle accelerometer which is highly responsive, ensures a nice smooth, uniform stopping action. And what's nice about it is it gives you continuous diagnostic check which alerts you to any problems. The integrated safe guards protect your vehicle, the trailer and the controller. It'll minimize drain on the car battery by entering power conservation mode after 30 minutes of inactivity. Keeps the trailer brakes from overheating by reducing power output to them during prolonged stops, and then we defend the brake controller and the trailer break away system against any shorts, prevents positive and negative power reversal with a built in polarity protection.

Now this brake controller is compatible with low voltage systems, PWM systems, ABS and cruise control. You can see it includes the mounting bracket and the mounting hardware. Now it does have a plug at the back here, the plug in vehicle specific brake controller adapter can be used for certain applications to reduce installation time. We do sell those separately on our website. If you put in your year and model vehicle, it'll show you if there's a vehicle specific brake controller adapter that would plug into this and then plug into your vehicle.

A few specs again, this is for trailers with up to four axles or eight brake assemblies, and it is designed for use with either electric or electric over hydraulic trailer brakes. It does come with a nice installation manual that'll describe how it hooks up and how it operates. But that should do it for the review on the Curt Assure proportional trailer brake controller with dynamic screen for one to four axle trailers..
