ADB Airfield Solutions Introduces New Advanced Power Supply System Designed Specifically for LED Fixtures

New system maximizes energy efficiency and presents solar option

COLUMBUS, OHIO (December 8, 2010) – ADB’s Advanced Power Supply (APS), available in 1kW or 2kW units, is a new generation of power equipment designed specifically for LED airfield lighting fixtures. The APS unit unlocks the potential of solar-powered airfield lighting circuits, leverages existing series circuit infrastructure, and maximizes power supply efficiency while reducing maintenance costs. The first solar-powered circuit using ADB’s 1kW APS system has a projected savings of 90 percent compared to the airfield’s previous spending.

ADB’s stand-alone Advanced Power Supply Systems (APSS) also provide airports with substantial benefits, because the system maximizes power supply efficiency, eliminates the LED fixture’s internal power supply, and allows the airport to reuse its existing series circuit infrastructure, including existing L-824 wire/L-823 primary connectors. The APSS consists of an APS unit using Pulse Width Modulation technology – the most efficient method to drive LED fixtures – and APS-specific LED fixtures to maximize energy efficiency and minimize LED fixture complexity when compared to traditional incandescent or LED 6.6A (or 20A) systems. Other benefits of the APSS include:

• maintenance staff familiarity with series circuits
• lower operating voltages, which translate to increased safety
• the ability to regulate LED intensity with PWM
• the elimination of L-830 isolation transformers on in-pavement fixtures, including electrical losses associated with those transformers
• much lower overall system acquisition cost for retrofit applications where airports reuse existing series circuit infrastructure
• it’s a good choice for overall system simplicity on unswitched/non-monitored circuits

Because the maximum APS output voltage is less than 500V for the 1kW APS or 1,000V for the 2kW APS, there is increased safety and longer series circuit wiring component life. For new installations, standard 600V or 1,000V cable can be used. The physical size of the APS, which is available in either 3 or 5 Brightness Steps, is greatly reduced compared to traditional CCRs, minimizing vault space required and building costs for new installations. For existing installations, a simple pull-and-replace process for installing LED fixtures allows for a rapid change-over.
