Technical Details


General System Specifications

  • KNX Power Supply: 29VDC
  • KNX Current Consumption: 8mA @ 29VDC
  • External power supply: from 12 to 30VDC (constant voltage power supply)
  • Operating temperature: 0 ¡C to 45 ¡C
  • Assembly: Independent control assembly device. Connect LUMENTO as near as possible to both, the load to dimmer and the external power supply.
  • Bus power failure response: Data saving
  • Response when restarting bus: Data recovery
  • Operation Indicator: Programming LED: programming mode (red lighting), safe mode (red blinking). Test LED: in test mode, red, test channel 1 (R); green, test channel 2 (G); blue, test channel 3 (B). Reverse polarity of external power supply is indicated by the test LED in orange light. If there is not an external power supply connected it blinks in orange. If the currents selected by parameter and by selector switch don't match it blinks in white. Overheating protection: the test LED lights in red (continuous level1 of protection, blinking with level 2 of protection).
