Self Contained LED Marine Lantern Type PMAPI SC35

Self Contained LED Marine Lantern

Range : 3 – 6.3NM at 0.74T
Ideal for : buoys, piers, docks, jetties, marinas, fixed or floating structures

The PMAPI-SC35 is a weather protected self-contained marine lantern with an LED light source that can be combined with optional battery power or solar panels.

  • Independent operation for extensive time periods.
  • High intensity LEDs on a metal core PCB for maximum useful life.
  • Flexible electronic configurations.
  • Use on offshore platforms, port and harbor, aquaculture, fixed or floating structures.

Features :

  • Configurations : SS (Standard Solar) & LS (Large Solar).
  • Rugged, weather-resistant construction materials: High impact resistant polycarbonate for ice, ultraviolet exposure, salt air and seawater spray at a wide range of ambient temperatures.
  • High intensity, energy efficient fan beam LED array: Maximum visible range up to 7.8NM at 0.85T pending flash character in optimal conditions.
  • IR Remote : Powering on & off, set / retrieve configuration parameters such as flash pattern, effective intensity, day/night control, etc.
  • IALA approved colors : Single color LED engine – white, yellow, red or green.
  • Serviceable : Battery pack is easily disconnected and replaced.
  • Integrated bird deterrent: No additional accessories required.
  • Longevity – Estimated average service life of 10 years.

Performance Features:

  • Intensity control : Effective lantern intensity set on Schmidt-Clausen method.
  • Flash character control : 256 programmable flash characters and 2 custom flash characters.
  • Day/Night transition level settings : Programmable for active at all times or only after sunset. Day / Night level settings (sunset / sunrise transition) can be field programmed.
  • Calendar control – Programmable season on/off date.
  • Input protection – Lantern power input from the battery is reversed polarity protected for field repair or light head replacement.
  • Ripple delay – 0.05 to 12.7 seconds & master/slave sync options.
  • Storage mode – Automatic storage mode with adjustable automatic wake up.
  • Programmable sleep and test modes.
  • Battery low voltage cutoff.
  • Battery voltage and internal temperature LED flashing reports, triggered by commands from the IR remote control (unit will flash 1 1 9 sequences for a 11.9 V battery for example).
  • Battery voltage and internal temperature could be interrogated during day time, even when the lantern is off by the photocell control system.
  • Dynamic compensation circuitry for the candela low output, based on internal temperature, LED flash duration and LED color, to keep always the same programmed output intensity.

Optional Features :

  • GPS Synchronisation : Optional internally mounted hardware will allow the lantern to flash in-sync with other PMAPI and third party lanterns that are GPS synced.
  • External I/O port : Allows connection to an external monitoring device or for hardwired synchronisation to other lanterns.
  • Charging port : Charge / recharge the battery prior to installation.

    Class A, B and C compliant in accordance with USCG 8th District 33 CFR Part 67 for artificial island and structures, and 33 CFR Part 66 for 3 and 6.3 NM private navigation aids.
