Short description
The digital booster amplifies the DCC signal in digital systems. It
enables higher load currents for tracks divided into independent
sections.
Applicable supply units
We recommended the use of the TM-87380 type 230 V safety
mains transformer is for supplying the booster.
Parameters of the transformer:
Output voltage: 16 VAC
Max. output current: 5 A
Power rating: 80 VA Input
voltage: 230 VAC
Other transformer types with similar parameters (16 VAC,
min. 80 VA) may also be used.
Grounding and power supply of the booster
To avoid interferences and ground-loops, in larger networks which
contain more boosters, it is required to operate the boosters with
a common grounding point. The booster is weakly grounded (by
100 kOhm internal resistor) when it is connected to the LocoNet 1
terminal.
If the length of the network (exceeding 40 resp. 50 m) requires
the use of a separate, thicker ground wire, the “GROUND”
connector of the booster must be used for connecting the common
ground wire. (see Figure 2)

Attention! Each booster must be powered by an own supply unit.
Never power more boosters from a common power source!
If the booster is operated from LocoNet, the signal arriving
from the centre (or the previous booster) must always be
connected to the LocoNet 1 connector and the diversion to the
LocoNet 2 connector.
