Information for use
sera LED Digital Dimmer
Please read these instructions carefully and keep for future use. When forwarding this unit to third
parties, this information for use is also to be handed over.
The sera LED Digital Dimmer is a controller for pro-
gramming sera LED lighting appliances such as the
sera LED X-Change Tubes, sera LED aquaria and
the sera LED lights. You can adjust maximum bright-
ness and use the dimmer as a time clock. In combi-
nation with the sera LED X-Change sunrise Tubes
sunrise and sunset can be simulated.
SAFETY PRECAUTION
Use the sera LED Digital Dimmer only as described
in this information for use. It is a low voltage dimmer
for a range of 10 – 20 V. The maximum current on the
input side should not exceed 3 A. Maximum input
voltage cannot exceed the output voltage.
Application
The sera LED Digital Dimmer uses phase control:
the brightness of the connected LED lamps rises with
increasing frequency in programmed steps. In re-
verse, brightness is decreased by declining frequen-
cy signals from the dimmer. Adjustment can be done
either automatically or manually.
Application range
The sera LED Digital Dimmer can be used in a ver-
satile way and allows controlling the sera LED
X-Chan ge Tubes as well as the sera aquaria and
sera LED lights.
sera LED X-Change System
The sera LED Digital Dimmer allows operating one
or more sera LED X-Change Tubes (also different
lengths) up to a total of 60 W.
sera LED aquariums
All sera LED aquaria such as the marin Biotop LED
Cube 130, the Biotop LED Cube 130 XXL, the Biotop
Nano LED Cube 60 and the Biotop Nano LED
Cube 16 can be operated and programmed with the
sera LED Digital Dimmer.
sera LED lamps
The sera Nano LED light and the sera LED light,
both equipped with sera LED Chips, can be con-
nected solely or combined with more units by the
sera LED Triple Cable, and can be programmed with
a single sera LED Digital Dimmer.
When connecting several lamps/units of the same
voltage (for example do not combine 12 V and 20 V
lamps, but only 12 V and 12 V or 20 V and 20 V), it
is necessary to choose a suitable electronic bal -
last. Make sure the output voltages of the ballast and
the operating ranges of the LED lamps are identi -
cal. For instance, never connect a 12 V LED lamp to
a 20 V ballast. Warranty of the devices will be void in
case of damage as consequence of inappropriate
use.
When the sera LED Digital Dimmer is used with oth-
er LED lamps or illuminating light units, make sure
that the maximum current flow is not exceeded, and
that the lamps are really dimmable in the range of
10 – 20 V. Several LED lamps can be connected to
one ballast.
Kit includes (1)
1.1 sera LED Digital Dimmer with cable and 5.5 mm
barrel connectors
1.2 holder
1.3 screws (4 pieces)
Assembly instruction
The sera LED Digital Dimmer should be connected
between ballast and LED lamp. Should you intend to
control more than one light unit, please connect the
sera LED Triple Cable to the outlet connector of the
dimmer. By adding more triple cables you can even
attach more appliances. The barrel connectors of the
cables do not allow confusion, and polarity reversion
cannot occur.
Location
The sera LED Digital Dimmer should be installed
in an easily accessible and dry place. Use the hold-
er for installing the dimmer into the cabinet or where
you prefer. The holder (1.2) can be attached with
4 screws (1.3).
Operation
