AGB III is the third generation of automatic speed limit-
ers. Its construction corresponds to European regula-
tions. In addition to the top speed limiter, which limits
vehicle speed to a preprogrammed value, the unit in-
cludes a variable speed limiter for use at speeds be-
tween 30 KPH and the maximum speed limit. By
pressing the variable speed limiter switch, the driver
can choose any speed within this range, and the con-
troller limits the speed according to the driver’s de-
mand. Alternatively, the unit can be preprogrammed for
a second speed limit below the maximum speed limit.
The electronic control unit is self-diagnosable. The
electrical actuator is a device that has been tested
and proved over years of operation in everyday use.
Various application sets are available.
