Dimming actuator, 1-gang for KNX 20 – 500 W/VA

• 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.

• Power expansion using Gira power boosts.
• Installation on DIN top-hat rail.
• VDE approval in accordance with EN 60669-1, EN 60669-2-1.

• Connection and junction terminal for KNX included with delivery.
