Power Station LV101

DIGITAL plus
Supplying power to a large model train layout
As in conventionally operated layouts, a sufficient power supply
is prerequisite for the safe function of a digital layout.
Locomotives, interior lights in rolling stock, turnouts, signals etc.
all get their power from the Power Station, along with their
commands. If the devices you have connected to an LV101
together require more than 3.0A, the safety circuit of the LV101
will activate. You will have an overload situation as described in
the section "Connecting the Power Station" above.
The current use of your layout is the sum of the following:
•
locomotives in operation: depending on scale and load .2
Amps to 2 Amps. In N-scale, calculate ½ Amp, for H0 scale
estimate 1 Amp and for larger scales 2 Amps per
locomotive, and you will normally have some reserves.
•
standing locomotives: without lights 1.5mA, with lights
approximately 50mA per light bulb
•
rolling stock with lights: per light bulb approximately 50mA
If the output of a single LV101 is not enough to supply the
layout, then divide the layout into several power districts.
Additional LV101 units then will supply those areas with
approximately 3.0A each (one LV per power district)
In the supply area of one LV101, the current load of all
simultaneously operating locomotives must not exceed 3.0A
(including the current used for lighting in rolling stock).

The command signals reach additional LV101s through terminals
C and D of the first one. Each LV101 must be connected to its
own transformer. The number of transformer/Power Station
combinations needed for the layout thus depends on the power
