Booster B-3
RailCom
The booster B-3 can provide the so-called RailCom-cutout needed to
transfer RailCom-feedback data in RailCom-monitored sections.
When using the B-2 with control units sending a DCC signal but not
compatible to RailCom, providing the RailCom-cutout can cause
malfunction. Some older DCC vehicle decoders and current decoders
(especially of US American manufacturers) which are not designed for
use with Railcom, do not react to driving commands properly with the
RailCom cutout activated. With sound decoders not compatible to
RailCom interferences in the sound playback can occur.
Thus with the B-3 it is possible to switch RailCom on or off. With pure
Motorola control units, malfunction due to sending the RailCom-cutout
is impossible on principle.
Using the ABC-braking method
The booster amplifies the track signal completely symmetrically. This
allows the ABC-braking method to be used in DCC-controlled layouts.
The DCC-input of the B-3 is isolated through an opto-coupler.
Balanced track voltage
The booster B-3 provides a regulated track voltage, which can be set to
a value of 12, 15 or 19 V. At delivery the track voltage is set to 19 V.
Regulating the track voltage to a constant value prevents changes in
locomotive speeds and lighting brightness, resulting from voltage
variations.
