dimm.act. 2-g 2 x 300 W/VA KNX DRA

Dimming actuator, 2-gang for KNX 2 x 300 W VA DRA plus 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). Building site operation: Outputs can be operated manually without bus voltage with operating voltage only. Functions: Independent control of the dimming channels. 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. Notes : Power extension using Gira power boosters. Installation on DIN top-hat rail. VDE approval in accordance with EN 60669-1, EN 60669-2-1.
