The worldwide
standard for

building control
Universal dimmer for LEDs and
conventional illuminants
The new universal dimmer N  in
the new design with DIN rail-mounted
devices expands the Siemens GAMMA
instabus lighting control product
range. Its four independent channels
enable the new product to deliver
seamless dimming adjustment for
dimmable LED retrofit bulbs and bulbs
in all other dimmable categories, with
no minimum load. The universal
dimmer‘s front panel makes it easy to
check and operate. Channel bundling
allows outputs to be combined so the
load can be increased up to , VA.
Dimming LEDs
The universal dimmer fulfills all requi-
rement for dimming all dimmable
bulbs, and dimmable LED bulbs in
particular. It reliably dims even small
bulb outputs of just a few watts of
power. Despite the low load, the LED
dims to complete shut-off.
Optimal dimming behavior
The universal dimmer has the same
hardware and software features of the
new generation of the GAMMA DIN
rail-mounted device. The ETS commis-
sioning software permits users to
configure optimal dimming behavior.
Especially useful are the setting op-
tions for predefined or freely defined
dimming curves.
Intuitive front panel
Status LEDs and push-buttons permit
convenient operation at the front
panel to check the installation. With
one click, users can switch and dim
the ballasts, configure the channel
bundling, and detect faults. Channel
bundling can be adjusted directly,
without ETS.
