RS 525/23


Universal Dimmer, 1 x AC 230 V, 10…250 VA, (R,L,C load)

  • Output for switching and dimming resistive, inductive or capacitive loads
  • Automatic adjustment to leading edge or trailing edge control, depending on the type of load
  • Rated frequency 50…60 Hz
  • Electronic protection of the output against overload, short circuit and temperature rise
  • Bus-powered electronics
  • Integrated bus coupling unit, Bus connection via bus terminal block
  • Type of protection: IP 20
  • Rated operational voltage AC 230 V
  • Rated power at +35°C ambient temperature: 10…250 VA
  • Screw-less terminals for connection and through-wiring of untreated single-core, stranded or multi-core conductors, 0.5 … 2.5 mm2
  • With bus connection module
  • Modular installation device for mounting in AP 118 automation module box or AP 641 room control box

Additional functionalities GAMMA

  • Selectable mode for each output (normal mode, one- or two-level timer mode, blinking)
  • Adjustable on- and off-delay
  • Separately adjustable dimming time from 0…100 % for switching on / off and dimming brighter / darker
  • Two dimming value objects, each with individually adjustable dimming time from 0…100 %
  • The ability to switch an output on or off by dimming brighter/darker
  • Adjustable dimming value when switching on
  • Immediate activation (jumping) or dimming to a new dimming value
  • Selectable additional status object switching and / or status object dimming value for each output
  • Additional object for each output for blocking / releasing the output
  • Sending of status objects on request and / or automatically after a change
  • Adjustable blocking time for sending status objects after restart and bus voltage recovery
  • Adjustable dimming value for each output in the event of bus voltage failure and recovery, as well as for mains voltage recovery
  • Additional night mode object for time-limited switching on the output (and hence illumination) at night
  • Adjustable on period at night or with timer mode
  • Selectable warning of imminent switching off the illumination by dimming to 50 % of the previous dimming value during night mode or timer mode
  • Integrated 8-bit scene control and integration of each output in up to 8 scenes
  • Separately adjustable dimming time for scene control
  • Selectable counting of operating hours and with threshold monitoring of the operating hours
  • Selectable counting of load cycles and with threshold monitoring of the load cycles
