Overview
LED illumination is getting more
popular. By dimming the output of
the LED strips (12V or 24V series)
an attractive atmosphere can be
created.
A dimmer module is placed
between the external LED power
supply and the LED strip.
The use of Pulse Width Modulation
(PWM) greatly reduces heat development inside the dimmer module
compared to linear regulators

Use with a velbus system
The dimmer module can be part of a

system and controlled by a
12/24V LED strip
DC power
Connect the bus to the module (beware of the polarity). Connect the 12V to 18Vdc to the module (beware of the polarity).
A 12 or 24Vdc power supply is required for the LED strips. That power supply is completely separated from the Velbus power
supply. When connecting, make sure to use the correct polarity, as using the wrong polarity will blow the internal fuse.
The fuse can be replaced by removing the plastic power supply terminal cover.

To interconnect the Velbus

When many of modules (more than 10)
are connected to the cable or longer
cable lengths (more than 50m) are

AC power
The dimmer module can be used in combination with a direct current power supply (12 or 24V) to
dim LED strips (12 or 24V).
The function of the connected pushbuttons is set via the ‘Mode’ rotary switch.
The switch-off time (or dim time in slowly on/off dimmer mode) is set via the ‘Time’ rotary switch.
The address must be set to ‘00’ to disable communication with the Velbus

system.

2. Address selection
Every module in the system must have a unique address. When the Velbus® is not used, the address must be set to ‘00’ to
disable communication with the system.

REMARK WHEN USING VELBUS:
Normally only 2 ‘TERM’ terminators
must be used in a complete Velbus
installation. Usually this will be on
one module inside the distribution
box and on the module which is
physically located furthest from the

On all other modules, the terminator

ENGLISH
Depending on the setting of the ‘MODE’ rotary switch the dimmer module will act as follows:
Mode Description
Pressing the pushbutton will switch on the LED strip. When the set time expires the LED strip is switched off.
0
Pressing the pushbutton while the LED strip is already on will switch it off immediately.
Pressing the pushbutton will switch on the LED strip. When the set time expires the LED strip brightness will slowly diminish to be
1
completely off after 30 seconds. Pressing the pushbutton while the LED strip is already on will restart the timer.
A short push will switch on the LED strip (full brightness). Another short push when the LED strip is already on will switch it off.
2
Push and hold will dim the LED strip up to maximum or down to minimum brightness. The next push will dim in the opposite
direction When the set time expires the LED strip is switched off.
A short push will switch on the LED strip (brightness as memorized since last use). Another short push when the LED strip is
3
already on will switch it off. Push and hold will dim the LED strip up to maximum or down to minimum brightness. The next push will
dim in the opposite direction. When the set time expires the LED strip is switched off.
Operating the push button will turn on the LED strip to full intensity. Each time the push button is pressed within 5 seconds after the
4
previous operation the light intensity will modify with 25%. If the LED strip is on and the previous operation happened more than 5
seconds ago, the LED strip will turn off. When the set time expires the LED strip is switched off.
Pressing the pushbutton will slowly turn on the LED strip to full brightness. The duration to achieve maximum brightness is
5
determined by the ‘TIME’ switch. Pressing the pushbutton while the LED strip is already on will switch it off immediately.
Pressing the pushbutton will switch on the LED strip to full brightness. Pressing the pushbutton when the LED strip is on will slowly
6
decrease brightness until the LED strip is off. The duration to switch the LED strip to off is determined by the ‘TIME’ switch. Pressing the pushbutton during decreasing brightness will turn the LED strip back to full brightness.
Pressing the pushbutton will slowly turn on the LED strip to full brightness. Pressing the pushbutton when the LED strip is on will
7
slowly decrease brightness until the LED strip is off. The duration to achieve maximum brightness or to switch the LED strip off is
determined by the ‘TIME’ switch.
Remarks:
When the ‘TIME’ rotary switch is set to ‘0’ the dimmer module will always work in instant control, no matter what operating mode is
set. On other words, the LED strip will light up as long as the pushbutton is pushed. When the ‘TIME’ rotary switch is set to ‘F’ the
dimmer module will not automatically switch off or the dimming speed will be maximal when the module is set to slowly on, slowly
off or slowly on/off mode.

Overzicht
Ledverlichting wordt steeds
populairder. Door de uitgang van
de ledstrips (12V- of 24V-reeks)
te dimmen, kunt u de ruimte
sfeervol verlichten.
Een dimmermodule wordt tussen
de externe voeding en de ledstrip
geplaatst.
Dankzij het gebruik van de PWMtechnologie (Pulse Width
Modulation) genereert de
dimmermodule veel minder
warmte dan de lineaire regulator.

1. Aansluitschema's
In combinatie met het Velbus® systeem
12/24V LED strip
DC power
Sluit de bus aan op de module (let op de polariteit). Verbind de 12V tot 18V gelijkspanning van de Velbusvoeding met de
module (let op de polariteit).
Er is een aparte 12 of 24V gelijkspanningsvoeding nodig voor de ledstrips. Die voeding is volledig gescheiden van de
Velbusvoeding. Let op de polariteit bij het aansluiten want bij verkeerd aansluiten zal de interne zekering doorsmelten.
De zekering kan vervangen worden door het plastic beschermkapje te verwijderen.
De dimmermodule kan opgenomen worden
in het Velbussysteem en bestuurd worden
door het bedienings-paneel VMB4PD of
door drukknoppen aangesloten op een
drukknopinterface VMB8PB.
Om de Velbusmodules met elkaar te
verbinden gebruikt men best een twistedpair kabel (EIB 2x2x0.8mm2, UTP 8x0.51mm
- CAT5 of gelijkwaardig).
Indien er veel modules (meer dan 10) op
de kabel aangesloten zijn of bij zeer lange
leidingen (langer dan 50m) is het belangrijk
om de draaddoorsnede voldoende dik te
voorzien (0.5mm
2
of meer).
