ALSF/MALSR 400VDC - Approach Lighting System, Incandescent

Low-Voltage ALSF High-Intensity and MALSR Medium-Intensity Approach Lighting Equipment with Elevated and In-pavement Sequenced Flashers are used at airports and military air bases to provide landing approach guidance, such as runway alignment, height perception, horizontal reference, and roll guidance extending from the landing threshold outward (2,400-3,000 feet) into the approach zone. Flasher operating voltage is +400V DC instead of +2000V DC used in traditional systems, improving safety. This also allows standard 600V cable to be used between the flasher and Individual Control Cabinet (ICC). This eliminates the need for high voltage interconnecting cable. MALSR sequenced flashers can be easily expanded to ALSF at a later date.
