Universal dimmer actuator 1-way with three inputs for installation in a 60 mm switch box. Potential-free contacts can be connected to the three inputs. An NTC temperature sensor can optionally be connected to the third input. The inputs and the KNX are connected via a 6-core, approx. 30 cm long connecting cable. The connecting cable for the inputs can be extended to a maximum of 10 m. KNX Secure compatible. KNX software functions: Dimmer actuator functions: Switching and dimming lamps. Switch-on and dimming behavior can be adjusted. Feedback of the switching state and the brightness value. Soft ON, soft OFF and time dimmer. Dimming or jumping to brightness values. Time-delayed switch-off if a switch-off brightness is not reached. Short circuit and load failure signal. 64 scene function. Locking operation via an object with a parameterizable brightness value at the start and end of the lock. Behavior of the dimmer actuator after bus voltage returns. Input function: Free assignment of the switching, dimming, blind and value transmitter functions. Locking object. Behavior when the bus voltage returns. Temperature, brightness, color temperature. Switching: two switching objects per input. Command on rising/falling edge (ON, OFF, TOGGLE, no reaction). Dimming: Single-surface and two-surface operation. Time between dimming and switching and dimming step values. Telegram repetition and sending stop telegram. Blind: Command on rising edge (none, UP, DOWN, TOGGLE), operating concept (Step - Move - Step or Move - Step). Time between short and long actuation. Slat adjustment time. Value transmitter and scene ext. Input: Edge (button as normally open contact, button as normally closed contact, switch) and value on edge. Value adjustment via long button actuation for value transmitter. Scene ext. Unit with memory function. Logic module: Link, converter, locking element, comparator, limit value. Nominal voltage: AC 230 V, 50/60 Hz. Connected load 25 °C: Incandescent/halogen lamps: AC 230 V, 20-230 W. Low-voltage halogen lamps: 20-210 VA wired transformer / 20-210 W electric transformer. LED phase control: AC 230 V. 20-210 W/VA, AC 230 V, 20-230 W. Connected load 45 °C: Incandescent/halogen lamps: AC 230 V, 20-210 W. Low-voltage halogen lamps: 20-160 VA wired transformer / 20-160 W electric Transformer.LED phase control: AC 230 V.20-160 W/VA, AC 230 V, 20-210 W. Inputs: 3.Dimensions: 48x50x28 (WxHxD).Note: For installation in double/electronic box (Kaiser). A minimum distance of 4mm must be maintained between the 230V connection and the connection for the KNX/inputs (SELV).
