Ambient sensor (photocell) for twilight-night intensity change in accordance with ICAO and FAA for all OBSTA lights or for the change of color and light-intensity of the led obstaflash series

  • plug-in modular construction with plated contact surfaces
  • possibility to rotate the censor on its base
  • automatic control of the red or dual obstruction lighting according to ambient light in compliance with FAA and ICAO twilight/night triggering level (2 ouputs available for night and twilight)
  • timer to prevent the functioning of the cell at inopportune times (lightning)
