What is DSC?

The Dexter Sway Control system is a critical safety item to stabilise the sway of a trailer or RV by continuously monitoring trailer yaw, side-to-side movement, left and right of the tow vehicle.

Some of the causes of sway are:

  • Poorly designed caravan
  • Axle located too far forward
  • Incorrect ball height
  • Unsuitable tow-vehicle & caravan combination
  • Under inflated tyres
  • Incorrect weight distribution

How the Dexter Sway Control (DSC) works:

The DSC continuously monitors trailer yaw, side-to-side movement, left and right of the tow vehicle. A powerful, rapid processing capability captures the critical elements that affect sway conditions, then uses the information to sense how the sway will proceed without driver intervention. The data collected in the event of sway is used to apply the brakes on the correct side of the trailer in a timely manner and with the proper braking level required based on sway conditions. DSC works independently of the tow vehicle to dampen the trailer sway, quickly bringing the trailer under control.

Why choose the Dexter Sway Control (DSC)?

  • Continually monitors trailer/caravan yaw - uses similar technology to that used in automotive stability control systems.
  • Corrects sway quicker; system reacts as soon as sway begins.
  • Controls left and right brakes separately, resulting in quicker sway correction.
  • Sway control braking level is automatically varied (not preset) based on the severity of the sway – smoother response.
  • Closed loop feedback. Adjusts braking voltage to correct more smoothly and efficiently.
  • One size fits all. No calibration, van weighing etc.
  • Will adjust automatically to varying loads (e.g. tank full versus tank empty) thus braking settings are optimal, independent of vehicle mass.
  • No need to rewire tow vehicle – powered from caravan battery, saves owner money.
  • 2 year limited warranty.
  • CIL 10% insurance discount.

Features Benefits
LED Status Light RED/GREEN LED light on a 10 inch lead for mounting in an easily seen location to show the functional status of the unit with different flashing modes for diagnostic troubleshooting.
Automatic Off-Road Mode The module continuously monitors the sway sensor to detect and activate during trailer / caravan sway. It is also able to determine rough terrain conditions, during which it modifies the sway control braking. Upon exiting the rough terrain, the system is returned to normal operation.
Alternate Side Braking Technology Next-generation technology promptly detects trailer sway and responds by applying either the left or right brakes dampening the sway more quickly than other systems that apply brakes on both sides at the same time.
Trailer Sway Brake Level Auto-Adjustment Closed-loop sensory feedback allows the system to independently increase or decrease the right or left side brake levels to respond appropriately to the severity of the conditions to dampen the sway.
Fully sealed, water resistant The system is fully sealed and water resistant.
