The power supply of a model railway layout

As with conventionally operated systems and layouts, a sufficient
supply of electricity to the system is a precondition for the sure and
safe functioning of the Digital plus by Lenz
Locomotives, (coach) lights, points, signals etc. are power consumers.
The amplifiers supply this power and at the same time the control
information required by the decoders.
To find out whether the maximum current of the Digital plus by Lenz
system used is sufficient for the supply of your model railway system,
simply add up the power consumption of all locomotives running at the
same time as well as that of all other consumers. Use the following
approximate values for your calculation:
- running locomotives - depending on gauge and attached load, the
power consumption ranges from 200mA to 2000mA. Calculate per
locomotive 500mA for gauge N, 1000mA for gauge H0 and
with AC:
with pure DC:
When supplied with DC, it makes sense to select an input
voltage which is approx. 3V higher or lower than the set
output voltage (track voltage) or, if supplied with AC, equally
high or slightly lower. This avoids an unnecessary loss of heat
in the device which in turn could lead to an early thermal
switch off.
Settable between 11V and 22V in steps of 0.5V. In case of a
loads, this voltage can be lower depending on the transformer
used. The factory voltage setting is 16V.
The output current is limited to a maximum of 5A.
Depending on the transformer used, as well as its voltage and
the set track voltage, the constant current, which the amplifier
of the LV102 can supply, varies.
Example: When using the transformer TR150 and a track
voltage of 16V, the constant current is 4.5A.
Thermal overload protection. The switching off of the overload
occurs after approx. 100ms in case of constant overcurrent
(e.g. short-circuit).
