LED drivers give arena and outdoor lighting a sporting chance
Delta has introduced the Euco Arena Sport series of LED drivers. They deliver 1500W over three independent, programmable channels and a wide output range of 250 to 500V DC and is programmable to 500 to 1400mA.
The Euco Arena Sport Series LED drivers are designed for luminaire manufacturers providing industrial and commercial lighting applications, such as high mast lighting, recreational sports lighting, harbours, airports and car park lighting.
It is built on three independent output channels with a maximum power of 500W (1500W total). The offer precise tuning of the drive current and are equipped with dimming circuitry for DALI-2 DiiA-certified digital dimming to allow for adjustment of lighting levels from 0.1 to 100 per cent.
In addition to the driver architecture and circuit topology, Delta has achieved a very low typical current ripple of up to one per cent peak to peak. This parameter is important in televised events, points out Delta, because current ripple can cause LED flicker. Flickering lights affect the quality of sports broadcasts and limit slow motion options.
“Financial considerations play a significant part in recreational sports lighting, especially for stadiums,” said Tim Lee, vice president of Delta Electronics, EMEA. “Energy efficiency, resource conservation, maintenance, and sustainability are important factors that should be taken into account for any lighting installation. And using LED lighting is not just about electricity costs,” he added. The metal halide lamps still installed at many arenas can take considerable time to warm up. . . If they turn off in the middle of an important event, it may take half an hour or more for the lights to come back on.”
The Euco Arena Sport LED drivers use solid heat sinks that provide more contact area with the cold plate for passive cooling. Good heat management ensures the product is capable of operating with high efficiency across a long service life, said Delta.
The long lifetime and high reliability of Euco Arena Sport LED drivers have passed the 5000hrs plus accelerating life test (ALT) with harsh environment of +65 degrees C and 85 degrees humidity.
Depending on the installation environment and ambient temperatures, the maintenance intervals can be significantly increased, advises Delta. Euco Arena Sport Series LED drivers can be located up to 200m away from the luminaire, which means the drivers no longer need to be on a high mast that requires a bucket truck (which can damage grass fields) or industrial climbers for installation or maintenance. Furthermore, light designers can now use much lighter masts since the weight of the driver is no longer a consideration. Even when retrofitting LED lights at an existing facility, old masts can be easily replaced, says Delta
The Euco Arena Sports LED drivers have a low inrush current, which allows facilities to reuse existing circuit breakers if desired.
Two versions are available. The Euco-1K5140GLA model is designed for DALI 2 control interfaces and the Euco-1K5140GDA is for facilities that use RDM/DMX.
