Universal dimmer switch with rotary knob,
Power MOSFET up to 800 W. Automatic lamp
detection. Standby loss 0.2 watt only.
With adjustable minimum and maximum
brightness.
Modular device for DIN EN 60715 TH35 rail
mounting. 2 modules = 36 mm wide, 58 mm
deep.
Universal dimmer switch for lamps up to
800 W, depending on ventilation conditions,
dimmable energy saving lamps (ESL) and
dimmable 230 V LED lamps are also
dependent on the lamp elec tronics and the
dimming technology.
Up to 3600 W with capacity enhancers
LUD12-230V at the terminals X1 and X2.
Zero passage switching with soft start and
soft OFF to protect lamps.
Universal control voltage input 8 to 230 V UC,
electrically isolated from the 230 V supply
voltage and switching voltage.
No minimum load required.
Alternatively, PWM control with 10-24 V DC
at the PWM and GND connections.
The setting of the brightness level is stored
after switching off.
In case of a power failure the switching
position and the brightness level are stored.
If applicable the dimmer will be switched on
at the stored brightness level after the supply
voltage is recovered.
Automatic electronic overload protection
and over-temperature switch-off.

Function rotary switch
Maximum brightness (fully dimmed up) is
adjustable using the upper % rotary switch.
Use the middle % rotary switch to set the
minimum brightness (fully dimmed down).
The lower rotary switch sets the operating
mode:
ON: Permanent ON at maximum brightness.
Pos. 1 is an AUTO position and allows the
dimming of all lamp types. Switch on and off
using pushbutton on the device and/or push-
button connected to +A1/-A2. Dimming via
rotary knob.
Pos. 2 is a comfort setting for dimmable
230 V LED lamps which cannot be dimmed
down far enough on AUTO (phase cut-off)
due to the design and must therefore be
forced at phase control. Switch on and off
using pushbutton on the device and/or push-
button connected to +A1/-A2. Dimming via
rotary knob.
Pos. 3 is a comfort setting for energy saving
lamps which must be switched on at a higher
voltage so that they can be safely switched
on cold when they are dimmed down. Switch
on and off using pushbutton on the device
and/or pushbutton connected to +A1/-A2.
Dimming via rotary knob.
Pos. 4 is an AUTO position and allows the
dimming of all lamp types. Switch on and off
using switch connected to +A1/-A2. Dimming
via rotary knob.
Pos. 5 is a comfort setting for dimmable
230 V LED lamps which cannot be dimmed
down far enough on AUTO (phase cut-off)
due to the design and must therefore be
forced at phase control. Switch on and off
using switch connected to +A1/-A2. Dimming
via rotary knob.
Pos. 6 is a comfort setting for energy saving
lamps which must be switched on at a higher
voltage so that they can be safely switched
on cold when they are dimmed down. Switch
on and off using switch connected to +A1/-A2.
Dimming via rotary knob.
Pos. 7 is an AUTO position and allows the
dimming of all lamp types. Switch on and off
and dimming with PWM activation.
Pos. 8 is a comfort setting for dimmable
230 V LED lamps which cannot be dimmed
down far enough on AUTO (phase cut-off)
due to the design and must therefore be
forced at phase control. Switch on and off
and dimming with PWM activation.
In positions 2, 3, 5, 6 and 8 no inductive
(wound) transformers should be used.
OFF: Permanent OFF.
The LED under the upper rotary switch
lights up when the lamp is switched on.

1) Applies to lamps of max. 150 W.
2) Per dimmer it is only allowed to use max.
2 inductive (wound) transformers of the same type,
furthermore no-load operation on the secondary
part is not permitted. The dimmer might be destroyed.
Therefore do not permit load breaking on the secondary
part. Operation in parallel of inductive (wound) and
capacative (electronic) transformers is not permitted!
3)
When calculating the load a loss of 20% for inductive
(wound) transformers and a loss of 5% for capacitive
(electronic) transformers must be considered in
addition to the lamp load.
4) Affects the max. switching capacity.
5) Usually applies for dimmable energy saving lamps and
dimmable 230 V LED lamps. Due to differences in the
lamps electronics, there may be limited dimming
range, switch on and off problems dependent on the
manufacturer and a restriction on the maximum
number of lamps; especially if the connected load is
very low (for 5 W-LEDs). The comfort positions optimize
the dimming range, which, however, only gives a maxi-
mum power up to 100 W. No inductive (wound) trans-
formers may be dimmed in these comfort positions.
6) At a load of more than 400 W ventilation clearance of
½ module to adjacent devices must be maintained.
Must be kept for later use!
We recommend the housing for
