LT100 Digital Circuit Breaker 3
DIGITAL plus
Maximum current of the outputs
A maximum current of 50mA may flow at each output of LW130.
Ensure that the sum of the current draw of all lights connected to
one output is not greater than 50mA.
In an overload from too high current draw, LW130 will be
damaged! Damages from overloads are not covered by the
warranty!
Light bulbs generally have a current draw of 50mA, so that only
one light bulb may be connected per output.
Therefore if you want to use several lights per output (for instance
to display track occupancy), then preferably use LEDs with as
small of a current draw as possible.
Calculating the current draw of LW130
The current draw of LW130 is determined by the number and
type of connected lights. You can use light bulbs or LEDs, and, if
you like, in any combination. Simply add up the current draw of all
the individual lights. You then get the total current need for the
displays. To that is added the no-load current draw of LW130.
That is TBD mA.
The total current draw determined in this manner must be
available from the transformer that supplies your LW130.
Example:
Your LW130 has 6 light bulbs each drawing 50mA and 22 LEDs
drawing 5mA each connected to it. All together that makes for a
current draw of 410mA. Thus the transformer used to supply
power must be able to provide (at least) this current. If you also
want to supply additional LW130s with the same transformer,
then simply add together the current draws for each LW130 to get
the total current the transformer must deliver.
