78 Information SET-01
16.2 More power through more power stations
As is the case with conventional systems, a sufficient power supply
is required for reliable functioning of your Digital plus by Lenz
®
system. Locomotives, coach lighting, points, signals, etc. receive
their power and their control information from the power station. If
the total electricity consumption of everything connected to the
LV101, exceeds 52 Volt Amps the LV101 protective system is
activated.
The power consumption of your model railroad arises from:
- locomotives in operation – 200 mA to 2000 mA depending on the
size and the freight attached. You should plan on 500mA per
locomotive for size N, on 8000mA for size H0, and on 2000mA
for larger gauges. If you use these guidelines you will usually still
have reserves left.
- locomotives which are not in operation – without lighting draw
only 2.5 mA, with lighting approx. 50mA per bulb
- coaches with lighting –approx. 50 mA per bulb
With a LV101, the power consumption of all locomotives in
operation at the same time (plus the power consumption for the
lighting in the coaches) must not exceed 52 volt amps. If the power
consumption needs of your model railway is greater and if as a
result the power from the LV101 that comes with the SET-01 is not
alone sufficient for the supply of your system, it will be necessary
for you to divide the track system into several supply areas (called
power districts). Further LV101s can supply each additional power
district with a current of approx. 52 volt amps each.
The number of power stations you need depends on the total power
requirement of your model railroad. To calculate the total power
requirement simply add up the total used by each of the individual
power consumers. You can use the approximate values given above.
Divide the total power requirement by 3 and round the result up to
the next whole number. Now you have the number of LV101 power
stations which are needed.
The additional LV101s receive their control signals from the
terminals C and D of the first LV101. Each LV101 should be
connected to its own transformer. It is absolutely necessary that the
electrical circuits of all LV101s connected to each other have the
same polarity. This means that terminal J of the first LV101 and
terminal J of the following LV101s must be connected to the same
side of the track. Otherwise there will be short-circuits when the
sectioning gaps between power stations are crossed.
