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 (building
site operation also possible).
- The dimming actuator, 1-gang can also be used as speed
regulator for speed control of single-phase electric motors.
- Building site operation: Outputs can be operated manually
without bus voltage with operating voltage only.
Functions
- Independent control of the dimming channels.
- For building site operation, outputs can be operated manually
without bus voltage with operating voltage only.
- Central switching function for control of all dimming channels.
- Delay for actively transmitted feedback messages following bus
voltage recovery.
- Load type and dimming method can be configured: Universal
(with automatic calibration procedure), electronic transformer/LV
LED (capacitive/phase cut), conventional transformer/LV LED
(inductive/phase cut), HV LED (phase cut) or HV LED (phase cut).
- Feedback for "switching" and "brightness value".
- Dimmable brightness range can be set.
- Dimming behaviour and dimming characteristics can be
parameterised.
- Switch-on behaviour for a relative dimming command can be
parameterised.
- Bulb-saving switch-on and switch-off
- Automatic setting and scaling of the dimmable brightness range
when using universal power boosters.
- The performance of a dimming channel in the "OFF" state during
reception of a relative dimming command can be parameterised
(switching and dimming or no response).
- Alarm telegrams for short circuit, overload, and load failure.
- Feedback of connected load type.
- Block function or forced setting function can be parameterised
for each output.
- Time functions (switch-on/off delay, staircase light function).
- Staircase light function with advance warning function via
time-controlled reduction of lighting or activation of permanent
lighting.
- Linking function and up to eight scenes per dimming channel
possible.
- Elapsed operating time meter for recording switch-on time.
- Reactions after bus voltage failure and recovery can be set.
