Frequently Asked Questions
Can I use the ELG-100-48DA in a DALI-controlled museum or gallery lighting system?
Yes. The DA suffix indicates DALI dimming support, and the ELG-100-48DA integrates with DALI bus controllers for addressable dimming. Its 96W at 48V is appropriate for 48V LED tracks or strip systems used in display lighting where precise, scene-based control is required.
Is the ELG-100-48DA suitable for outdoor DALI-controlled architectural lighting?
Yes. The ELG-100-48DA is rated IP67, providing full dust-tightness and protection against temporary water submersion. Combined with DALI dimming, it is well suited for building facade, landscape, or architectural lighting installations managed by a DALI network.
How much 48V LED strip load can the ELG-100-48DA support?
The ELG-100-48DA provides up to 96W at 48V. For a 48V strip rated at 10 W/m, you can run up to 9.6 m per driver. For an 8 W/m strip, approximately 12 m. Divide 96W by your strip's rated power per meter and confirm with a 10% derating margin.
Can the ELG-100-48DA be used for 48V LED signage with DALI dimming in a retail environment?
Yes. The ELG-100-48DA's DALI interface and 96W output make it suitable for 48V illuminated retail signage where lighting levels need to be adjusted from a central control system. IP67 protection also accommodates outdoor or semi-exposed sign cabinet locations.
Does the ELG-100-48DA work in cold outdoor environments such as northern climates?
Yes. The ELG-100-48DA operates from -40°C to +90°C, covering the coldest ambient temperatures encountered in northern climate outdoor lighting. No warm-up period is required for startup in cold conditions.
What is the difference between the ELG-100-48DA and the ELG-100-48D2?
Both are 48V IP67 drivers in the same physical housing. The ELG-100-48DA (96W, 2A) uses the original DALI protocol interface, while the ELG-100-48D2 (100W, 2A) supports the newer DALI-2 standard with enhanced device interoperability. Choose the D2 variant for systems requiring DALI-2 compliance and the DA variant for legacy DALI installations.
