|Heliport System Controller Options
Use of a photocell is recommended for dusk-to-dawn control of operations of non-solar-powered systems. The DC photocell activates at 35 ft-cd and turns off at 58 ft-cd, and has a minimum rated life of 5,000 operations. Photocell is supplied in a UL stabilized high-impact polypropylene housing which contains the cadmium sulfide light sensitive element. Surge protection is provided by a metal oxide varistor rated at 320 joule. Operating temperature range of -40°F to 170°F. Measures 3.07" diameter by 2.15" high.
Programmable Timer Option
The programmable timer option is recommended for precise control of operating times. The programmable timer is a 12 hour, 8 event clock based timer. Multiple on/off times may be programmed into the timer. Each day can be programmed with its own unique timing pattern. An internal battery is capable of maintaining the clock and program memory for up to 3 months without external power.
With the dimming option, the lights can be dimmed at night to reduce glare. Three brightness levels can be selected. This option is available only with Low Voltage Dimming LED Flight Light Fixtures.
Output Power Options
The standard DC output model supplies up to 150 watts of power and is capable of controlling most small heliport lighting systems. For larger heliports, the power option may be added, extending the output power capability to 240 watts. The standard AC output model has a 20A breaker.
||Solar Power Option
The solar power option equips the system to run with free, renewable energy from the sun. Unprecedented in the industry, this green feature is the ideal long-term investment. Ongoing savings afforded by utilizing solar energy are calculated over the lifetime of the installation. The maximum output power is 240 watts.
