1.
These parts are not suitable for small children. There is
a danger of swallowing.
2. The product can be seen in figure 1. These instructions
are part of the product. Please retain them well.
3. The component is suited for direct and alternating
current from 6 – 16 volt. The current consumption
depends on the LED(s) connected, usually it is a couple
of milliampere.
4. At its input side, the component is equipped with slide-on
receptacles that fit with the small banana plugs
commonly used in the model train world. The usual
current supply with a yellow and brown wire is sufficient.
The polarity does not matter, as symbolized by the two
yellow plugs in figure 2.
5. At the output side, the component is equipped with
screw clamps that accommodate even the smallest
wires. Figure 2 shows very well that our smallest LEDs
with their 0,1 mm thin wires can be connected without
any problems. This has the advantage that for the
installation from below your model train facility you do
not have to do any soldering – overhead soldering can
be quite dangerous due to solder dripping down.
6. The component has a controller with which the brightness is continously adjustable from almost
zero to the maximum. As a protection against an eventual shifting, it is possible to remove the red
leveling disc with a little effort – of course it also can be put back on anytime. Besides this feature,
the component is working absolutely independent from possible voltage fluctuations on your facility
that usually are caused mainly by engaging further consumer loads like a track switch. In this case,
the electronics intervenes at once and the brightness of the LED remains unchanged.
7. The component works according to the principle of constant current. So it has no importance which
LED in which color or working voltage is connected to it. The voltage is regulated automatically,
what you can regulate with the controller is the current running through the LED.
8. It is also possible to connect several LEDs in series. So for example it is possible to connect 3 white
LEDs in series to the component. The only thing you have to observe is that the input voltage is
about 2 Volt higher then the voltage of all the LEDs together. So in this example the input voltage
should be between 12 to max. 16 Volt.
9. Parallel connections of LEDs are possible as well. But for this, the maximum current load has to be
observed – in this case about 20 mA. Furthermore with such maximum permissible values you
should keep an eye on the temperature of the small black component, the integrated voltage
regulator. After about 30 seconds it has reached its "working temperature". If this one stays below
hand temperature, everything is fine. If it gets too hot, you either have to reduce the too high input
voltage or the number of the LEDs connected in parallel.
10. For all the series and parallel connections of LEDs the following applies: Only use identical LEDs
on one component. Never mix the colors, since each LED with a different color has its own
technical data – and if the LEDs are mixed, the chain will only shine as brightly as its weakest
element. In extreme cases, strong differences in brightness can also appear when using only LEDs
of the same color. This is related to the manufacturing tolerances of the LEDs and in the rare case
this problem arises, the only thing that helps is to select the LEDs by hand.
