tams elektronik Booster B-6
Inrush time
The sum of the charging currents of buffer capacitors on vehicle decoders (especially sound
decoders) and additional external backup capacitors can become so high when the layout is
switched on that the short-circuit disconnection of the booster reacts immediately. This makes
it difficult to start up the layout when the short-circuit cut-off is active.
The B-6 can accept an increased current of 6 A for a short time (adjustable up to max. 500
ms) after switching on, regardless of the set cut-off current, and tolerates the brief collapse of
the voltage. This time is sufficient to charge buffer capacitors and backup electrolytic
capacitors. Only if the current does not drop again after the set time and the voltage does not
rise again, the short-circuit switch-off of the B-6 reacts (because then a "real" short-circuit can
be assumed).
Further information on inrush current: RailCommunity standard RCN 530 (at:
www.railcommunity.de).
2.5.2. Switching off in case of overtemperature
In case of overheating, the booster automatically switches off the track voltage for safety
reasons. Possible causes:
 obstruction of air exchange
 very high ambient temperature or direct solar radiation with simultaneous high load.
2.5.3. Watchdog function
The watchdog is used in PC-controlled layouts to check whether the digital signals are
transmitted in a booster circuit. For this purpose, the central unit (controlled by the PC
software) sends a DCC turnout setting command to a turnout address assigned to the B-6 at
intervals of max. 5 seconds. As soon as the B-6 no longer receives these commands, it
automatically switches off the track voltage.
After switching on the B-6, the watchdog function is initially inactive. It is activated by sending
an adjustment command to the assigned turnout address. This makes it possible to control the
layout without PC control without deactivating the watchdog function.
