2. Your Power-Splitter
With smaller nominal sizes, the current in the booster circuit is limited to 2 to 3 A in order to
protect rails and vehicles from damage in the event of a short circuit. The Power-Splitter
makes it possible to use a higher output current of the booster even with smaller nominal
sizes. It is connected between the track output of the booster (or the digital central unit with
integrated booster) and the track and splits the power of the booster into two or three
sections with a maximum current of either 2 or 3 A.
Use with all boosters
The Power-Splitter monitors the current in the connected two or three sections. It does not
interfere with the control of the booster and can therefore be used with all boosters.
The sum of the current consumption in the (two or three) connected sections must not exceed
the maximum output current of the booster. Otherwise, the short circuit shutdown of the
booster will react, even if the maximum current in one section has not been exceeded.
Absolute synchronicity
When crossing the separation points between booster circuits supplied by different boosters,
the following problems may occur:
 Equalising currents between the booster circuits due to different output voltages of the
boosters. Possible consequences: Short circuits on boosters, rails, wheels and sliders.
 Different digital signals in the two booster circuits due to different run times in the
boosters. Possible consequences: Vehicle decoders misinterpret these digital signals as run
or switch commands or as a command to switch to analogue mode.
The risks are all the greater the more different the construction of the boosters involved. Even
when using identical boosters, the problems described can occur due to component
tolerances.
When using the Power-Splitter, the output voltage and transit time of the digital signals are
absolutely synchronous in all connected booster sections. This ensures that the separation
points between the sections can be passed over without any problems.
