Avlite Systems produces solar-powered LED airfield lights, including models AV-70 and AV-425-RF. The AV-70 uses dual solar panels to charge a battery that powers 12 high-intensity LEDs through a microprocessor. It can operate reliably in low light and has IP68 water resistance. The radio-controlled AV-425-RF has a peak intensity of 92.5 candelas and uses an 18-watt solar panel to charge its 24 Ah battery. Avlite also produces obstruction lights like the universal DC model AV-OL-ILAB-12-R, which has adjustable intensity settings of 10 or 32 candelas and alarms if voltage is too low.

1. Avlite Systems
Solar Airfield Light
Global reputation for unsurpassed reliability…

2. TECHNOLOGY
Solar lighting systems
LED as light source
Solar LED lighting best value of money at 1/3 of
the cost of mains power lighting installation
Suitable as an emergency back-up system
installed alongside traditional mains-powered
lighting

3. OPERATING PRINCIPLE
Solar module converts sunlight to a electrical current used
to charge the battery at day
The battery provides power to operate at night
Microprocessor drives an array of LED through DC/DC
converter
Over charging protection
If the light has auto control then, On darkness, the
microprocessor initiate a program check and after
approximately 1 min. the light turn on.

Frequency: 2.4GHz
Nominal Voltage: 7.2 V
Battery Capacity: 4 Ah

21. AVLITE:AV-70-B-RF
 Works by using a hand held radio
controller and setup entire airfield,
airport or air base.
 Each light also has an operational
range of 1.4 Km

22. MODES OF OPERATION
 Always ON operational Mode
 STANDBY operational mode
 Dusk till Dawn Operational mode
Light Group
 Light is selected through rotary switch
 Controller can select any one of the 10 individual light
groups or all (By default 0)

23. Timeout Duration
 Visible only when timeout model is enabled
 Time before the LED intensity reverts back to its LOW
intensity state or standby
 Duration can set from 1 to 60 minutes
LED Bank Setup
 Allow a runway to change from visible to IR
Battery Diagnostic
 Used to check the battery voltage in every light
 If the battery voltage is within operational range the
light will turn off for 1 sec, flash once for 1 sec and
again turn off for 1 sec.
 Otherwise, the light will turn off for 1 sec, flash twice
then turn off for 1 sec
