N 554D31Universal Dimmer, 4 x 300 VA / 1 x 1000 VA, AC 230 V
• Four outputs for switching and dimming of resistive, inductive and capacitive loads
• Automatic adjustment to leading edge or trailing edge control, depending on the type of load
• Rated operational voltage AC 230 V
• Rated frequency 50 and 60 Hz
• Rated power at +45°C ambient temperature: up to 300 VA per output, up to 1000 VA with bundling of
adjacent outputs, without minimum load per output
• Electronic protection per output against overload, short circuit and temperature rise
• Maintenance-free terminals for connection and through-wiring of untreated single-core, stranded or
multi-core conductors, 0.5...2.5mm

• Manual operation buttons on the device for switching, dimming and activation of direct mode
operation
• Bus-powered electronics
• DIN-rail mounted device for mounting on rail TH35 according to DIN EN 60715
• Building site function for bundling the outputs and switching the building site lighting without prior
conguration of the device via ETS
• Object for surveillance of device function
• Object for retrieval of status values
• Per output with selectable operation mode (normal mode, one- or two-level timer mode, blinking)
• Adjustable ON-/OFF-delay
• Object Central Switching with separately congurable on/off delay selectable
• Separately adjustable dimming time from 0% to 100% for switching on/off and dimming brighter/
darker
• Switch an output on or off by dimming brighter/darker
• Congurable dimming curves for optimization of the dimming operation of lights
• Additional status object switching and/or status object dimming value
• Additional object for dimming with individually adjustable dimming time
• Congurable maximum and minimum dimming value via parameter and object
• Selectable object for limiting the maximum dimming value
• Selectable object for reporting of overload, short circuit and temperature rise
• Adjustable blocking time for sending status objects after restart and bus voltage recovery
• Integrated 8-bit scene control, linking of the output in up to 8 scenes
• Additional night mode object for time-limited switching on the output at night
• Post-triggering of the On period (On period extension) in time switch mode up to a selectable maxi-
mum On period extension via repeated (2x, 3x, 4x, 5x) post-triggering
• Selectable warning signal prior to imminent switching-off by brief off and on switching (ashing)
or by cutting the current dimming value in half at night or in time switch mode
• Selectable counting with threshold monitoring: operating hours, load cycles
