The Syncronizer is a brake controller for single and tandem axle trailers equipped with electric brakes. It modulates and controls the current from the battery to the trailer brakes. The longer the brake pedal is depressed the greater the current delivered to the trailer brakes until the preset brake power setting is reached.

Digital time-based circuitry with automatic and user-adjustable settings

Easy and Versatile Mounting

The Syncronizer can be mounted at any angle and in any direction, and is ideal for steep dashes that make typical units difficult to mount. It includes a mounting bracket and a standard four-wire hookup for quick and easy installation. It must be mounted in a location where the driver can see the Red Indicator Light. The driver must be able to reach and operate the manual slide.

Automatic Operation with Digital Display and Sleep/Standby Modes

The automatic mode modulates and controls the current from the battery to the trailer brakes and operates on a time-based circuitry. The longer the brake pedal is depressed, the greater the current delivered to the trailer brakes. The current will increase until it reaches the preset brake power adjustment setting. The Power Wheel is used to adjust the amount of current to the trailer brakes. It is responsible for obtaining smooth, proportional, and optimum tow vehicle and trailer brake responsiveness. To increase the amount of current, rotate the power wheel upward toward the top of the case. To decrease the amount of current, rotate the power wheel downward toward the bottom of the case.

Manual Operation and Override

The Manual Slide Lever is located on the front right side of the controller. The further the manual slide lever is moved from the right to the left, the greater the amount of trailer braking power. The manual slide lever operation is an independent circuit and overrides the power wheel adjustment to allow full braking effort when required. Use the Manual Slide Lever to apply the trailer brakes independently of the tow vehicle brakes or to override the automatic trailer brakes when more braking or less braking is required. The manual slide lever is used in emergency stop situations when more braking may be required than is available with the power wheel adjustment or for control of excessive trailer sway. The indicator light will illuminate from dim to bright as the manual lever is applied and remains off when the manual lever is released. The tow vehicle and trailer brake stoplights will still illuminate during the manual lever activation.
