OBSTA STI 48V
Part Number 113200

Cold neon discharge low intensity type A devoted to the night marking of all kind of obstacles supplied by a standalone DC power source in 48VDC

OBSTA STI 48V
  • Excellent luminous intensity with a vertical beam much larger than ICAO requirement,
  • Inherent generation of the «aviation» red,
  • Perfectly waterproof, light in hard made in hard glass
  • No grounding issue, class II
  • All wiring configuration available
  • Protected against transient overvoltages
  • Alarm by returning +48V in case of lamp failure or low power

The OBSTA STI is a one piece moulded assembly which includes a constant power converter and the proper discharge lamp (5 turns). The OBSTA STI includes : - a clear glass envelope, - a constant-power converter, - perfect watertightness, - no requirement for a ground connection, which avoids any voltage return from the earth (for example due to lightning). The overall is thus considerably improved. The OBSTA STI also includes : - protection against transient overvoltage, - circuitry to monitor the operation of the lamp and, in the event of failure, to trigger an alarm or light up an auxiliary lamp (if active redundancy circuits are used). The OBSTA STI is easy to install and requires no servicing.
