Frequently Asked Questions
Does the ELG-75-42DA work with DALI lighting control systems?
Yes. The 'DA' suffix indicates native DALI dimming, allowing the driver to receive DALI bus commands from a DALI controller or building management system. This makes it well suited for commercial offices, retail spaces, and hospitality venues where centralized digital lighting control is required.
Is the ELG-75-42DA waterproof enough for outdoor LED fixture use?
Yes. The ELG-75-42DA is rated IP67, providing full protection against dust and temporary water immersion. It can be installed inside outdoor sign enclosures, landscape fixtures, or building facade luminaires exposed to rain and humidity.
How many meters of 42V LED strip can the ELG-75-42DA drive?
The ELG-75-42DA delivers 75.6W at 42V. For a 10 W/m strip, maximum length is approximately 7.5 meters; for a 15 W/m strip, about 5 meters. Always divide 75.6W by your strip's rated wattage per meter and apply a 20% safety derating to protect the driver and strip.
Can the ELG-75-42DA be used for 42V LED strips in a museum or gallery lighting system?
Yes. DALI dimming enables precise, scene-based lighting control suitable for gallery and museum environments. The 75.6W at 42V output can drive a controlled run of 42V LED strips, while the IP67 rating provides protection against cleaning procedures that involve moisture.
Is the ELG-75-42DA suitable for powering 42V LED modules in a building facade with DALI control?
Yes. With DALI dimming, IP67 waterproofing, and a -40°C to +85°C operating range, the ELG-75-42DA suits outdoor facade and architectural installations controlled via DALI network. Its 100–305VAC wide input supports global mains voltages.
What is the difference between the ELG-75-42DA and ELG-75-42D2?
The ELG-75-42DA supports the original DALI protocol, while the ELG-75-42D2 supports DALI 2—the second-generation specification with improved two-way communication and expanded device type definitions. Both share the same 42V / 1.8A output and IP67 rating. Choose based on which DALI generation your controller supports.
