Lighting Dimmers and Twilight Switches
Modern dimmers use phase control to reduce or increase
the average voltage to the lighting load. The diagram below
shows this process in a graphical format.

This dimming method therefore provides opportunities for
energy savings as it reduces the total power consumed for
lighting under dimmed situations; these panel mounted
versions can be controlled by using external pushbuttons or
switches.
The table below shows the range of DIN rail mounted
dimmers available from hager, which are suitable for all light
sources including incandescent, LV and LVL halogen, and
fluorescent ballast.
A typical energy saving application using panel mounted
dimmers.
A large restaurant having two walls, made almost entirely
from windows, has dimmable lighting installed to allow each
dining area to be individually adjusted, by external
pushbuttons, to the required light ambience. During daylight
occupancy the areas nearest the windows are adjusted to
use the benefit of natural daylight hence saving energy during
this period.
