LEDs and conventional
Light-emitting diode lamps – LED
for short – are capturing the lighting
lighting markets, extensively replacing
conventional incandescent light bulbs
and halogen lamps. At the same time,
demand to control the brightness of
lighting is simultaneously increasing.
Dimming functions in LED lamps focus
more on ease and convenience than
on energy efficiency. The integrated
system electronics can only ensure
dimming of LED lamps if the LED is
marked as dimmable by the lamp
manufacturer.
Reliable dimming of LEDs
The universal dimmer fulfills the
requirement to dim all dimmable
lamps, and dimmable LED lamps in
particular. It allows reliable dimming
of even small lamp outputs of just
a few watts of power. Despite the
low load, the LED definitely dims to
complete shut-off.
Compact and versatile in its
applications
At normal lamp outputs the compact
modular series unit equipped with
four modules can be operated using
two load outputs, or at higher lamp
loads using only one load output. This
versatility simplifies planning effort
and product selection.
Application program and functions
The application program ensures
efficient planning, engineering
and commissioning. All functions
are designed and executed in the
same manner as in analog products,
there by reducing training needs.
