Features
- Dim actuator with integrated bus coupler.
- Switching and dimming of light bulbs, HV halogen lamps,
dimmable HV-LED lamps, dimmable compact fluorescent lamps,
dimmable inductive transformers with LV halogen or NV-LED
lamps, dimmable electronic transformers with LV halogen or
NV-LED lamps.
- Automatic or manual selection of dimming principle according to
load.
- Idle-state, short-circuit, and excess temperature-proof
- Manual actuation of the outputs independent of the bus.
- Temporary status display can be activated, link via
communication object possible across several actuators.
- Power extension using power boosters.
- To simplify configuration, all existing dimming channels can be
assigned to the same parameters in the ETS and hence identically
parametrised.
- Actively transmitting feedback or status messages can be
delayed globally after a bus voltage recovery or ETS
programming operation.
Dimming outputs
- Independent switching and dimming of the dimming outputs.
- The load type can be specified and the dimming principle
defined: Universal (with automatic calibration procedure),
electronic transformer (capacitive/trailing edge), conventional
transformer (inductive/leading edge), LED (leading edge) or LED
(trailing edge).
- Dimming characteristic curve per channel configurable in time
and value range for adaptation to the respective connected load.
- Dimmable range can be set: Switch-on brightness, basic
brightness and upper dimming limit.
- Performance on receipt of an absolute brightness value can be
set (dimming, brightening, fading).
- Performance during relative dimming up in switched-off state
can be set ( switch channel on, no reaction).
- Switching feedback: Active (transmitting to the bus cyclically or
when there is a change) or passive (object can be read out)
feedback function.
- Blocking function can be parametrised for each channel.
- Time functions (switch-on delay, switch-off delay).
- Staircase light function with advance warning function via
time-controlled reduction of lighting or activation of permanent
lighting.
- Can be integrated in the light scenes: Up to 16 internal scenes
can be parametrised per output.
- Delay time for scene retrieval can be configured.
- Dimming performance can be set when a new scene is called up
(brightening, dimming, fading).
- Visual feedback when saving a scene.
- Brightness value feedback: Active (transmitting to the bus
cyclically or when there is a change) or passive (object can be
read out) feedback function.
- For active feedback objects, the type of update can be set (when
the input object is changed or when the feedback value is
changed). This allows visualizations to be adapted individually.
