4. DB-4 connection to an Own Track Section:
The
DigitalBooster DB-4
is a
power amplifier
for your
digital model railway layout
.
The
digital current
of the
DigitalBooster DB-4
is available at the
clamp KL1
next to
the two light emitting diodes.
The DB-4 supplies
digital current
to the
own track section
via this clamp. This section
has to be
electrical separated
from the
adjoining track sections
because those
receive their
supply
from the
digital command station with integrated booster
or from
further booster
.
4.1. 3-Conductor Track System:
If the manufacturer of your digital command station
permits
a
common layout ground
(“brown”)
the
center conductor
of the
3-conductor track
has to be
isolated
at the
cross over joints
from one to the next booster electrical circuit. The
isolated center
conductor
gets the supply from the connection “
red
” of the
clamp KL1
of the
DigitalBooster DB-4
.
