KNX DRA Dimm.act. 2-g 2 x 300 W/VA [217200] KNX dimming actuator, 2-gang 2 x 300 W/VA Gira KNX system 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.
