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 operation of the outputs independent of the bus (building site operation also possible).
The dimming actuator, 1-gang can also be used as speed regulators 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.
The load type can be specified and the dimming principle defined: 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 or switch-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-hours meter for recording switch-on time.
Reactions after bus voltage failure and recovery can be set.
