4 Technical data of the LV103
Power supply
(input voltage)
with AC:
min. 14 Volt, max. 19 Volt
with pure DC:
min. 14 Volt, max. 24 Volt
When supplied with DC, it makes sense to select an input
voltage which is approx. 2 V higher than the set output
voltage (voltage on the track) 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.
Output voltage
(track voltage)
The voltage at the track is adjustable between 11 V and 22 V
in steps of 0,5 V. In case of a loads, this voltage can be lower
depending on the transformer used. The factory voltage
setting is 16V.
Output current
The output current is limited to a maximum of 5A.
It is adjustable from 2.5 A to 5 A in steps of 0.5 A.
Depending on the transformer used, as well as its voltage
and the set track voltage, the constant current, which the
amplifier of the LZV 200 can supply, varies.
Example: When using the transformer TR150 and a track
voltage of 16V, the constant current is 4.3 A.
Overload protection
Thermal overload protection. The switching off of the
overload occurs after approx. 200 ms in case of constant
overcurrent (e.g. short-circuit).
RailCom Detector
The LV103 is equipped with a global RailCom detector. This
detector receives data sent by decoders in channel 2 of the
RailCom packets.
This data is forwarded via the C,D lines to the LZV200 central
unit.
Housing
Aluminium
Dimensions
W 120mm x H 55mm x D 120mm
5 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
®
system.
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,
