Booster B-6
Cut the transitions between the booster circuits as follows:
For 2-conductor layouts: one rail. Make sure that you cut the same rail ("left" or "right") in
all booster circuits. In larger, unclear systems, it is recommended to cut both rails.
In centre-conductor layouts: the centre conductor.
3.2. Supply with several boosters
If possible, a layout should be supplied by identical boosters from the same manufacturer. If
necessary, ask the manufacturer whether and, if so, which booster models can be combined
with each other. Different booster models can be used on one layout if they are used for
completely separate parts of the layout (e.g. standard gauge line and narrow gauge line) or
separately for the tasks "switching" and "driving".
If boosters are connected to a central unit or a small digital control unit via the track output,
the integrated and external boosters should generally not be used together to supply the
layout with traction current. The booster integrated in the central unit can be used sensibly for
switching the accessory decoders in its own booster circuit.
Background information: Track signals
18 | Conception of the digital layout
The digital track signals that the boosters receive
from the central unit need a certain amount of time
to be processed and to get from the data input to the
track output. This processing time is different for
each booster due to its design. Even for boosters of
the same design it differs due to component and
manufacturing tolerances. A slight time shift of the
voltage characteristics is therefore the normal state.
The more different the run-through time of the
signals in the two boosters, the greater the time shift
of the voltage curves. This can go so far that a
positive voltage is already present at the output of
one booster and a negative voltage is still present at
the next booster, which is controlled by the same
central unit.
If the two booster circuits are connected to the
booster outputs with different polarity, opposite
voltages will be present. If the isolating points
between the booster circuits are bridged, the track
voltage is twice the set maximum track voltage.
