Frequently Asked Questions
Does the ELG-240-42DA support DALI lighting control?
Yes. The 'DA' suffix designates native DALI (Digital Addressable Lighting Interface) dimming control. The ELG-240-42DA can be addressed and dimmed individually or as part of a DALI group within a building management system.
Can the ELG-240-42DA be used for outdoor LED strip lighting in a commercial facade project?
Yes. The IP67 waterproof rating makes it suitable for outdoor facades, and it delivers 239.82W at 42V with 5.71A output current. The -40°C to +90°C operating range accommodates harsh outdoor climates.
How much 42V LED strip can the ELG-240-42DA drive?
The driver's maximum output is 239.82W at 42V. For a 42V strip rated at 15W per meter, that yields up to 15.9 meters (239.82 ÷ 15 ≈ 15.9 m). A safe continuous load is 80% of rated output—about 192W—or roughly 12.8 meters at that density; check your strip's rated watts per meter to verify.
Is the ELG-240-42DA suitable for wet indoor environments such as swimming pool surrounds?
The IP67 rating means the enclosure is dust-tight and protected against temporary water immersion, making it appropriate for wet indoor areas like pool surrounds or car wash facilities when mounted in an accessible but protected position.
Can the ELG-240-42DA be used in a smart building project that uses DALI for scene control?
Yes. The DALI interface allows integration with DALI-compatible controllers and scene management systems. It provides 239.82W at 42V, which is sufficient for large-area LED installations that need zone-level or fixture-level address control.
How does the ELG-240-42DA differ from the ELG-240-42B and ELG-240-42D2?
All three are 239.82W–240W, 42V, 5.71A units with IP67 enclosures. The ELG-240-42B uses 3-in-1 dimming (0–10V, PWM, resistance); the ELG-240-42D2 also uses 3-in-1 dimming with a slightly different control variant; the ELG-240-42DA is the only one with a DALI bus interface for addressable digital control.
