Frequently Asked Questions
Does the ELG-150-C1750DA support DALI dimming for smart building lighting?
Yes. The DA suffix indicates native DALI interface support, allowing the driver to be addressed and dimmed by DALI bus controllers. This makes it suitable for smart building projects requiring addressable, scene-controllable LED downlights or luminaires.
Can the ELG-150-C1750DA power LED downlights in a commercial office fit-out?
Yes. Operating at 1750mA constant current with a 43–86V CC range, it supports series LED arrays used in commercial downlight modules. The DALI interface enables integration with building management systems for zoned dimming and energy monitoring.
Is the ELG-150-C1750DA rated for outdoor installation in an exposed fixture?
Yes. With an IP67 waterproof rating, the ELG-150-C1750DA is protected against temporary immersion and can be installed in outdoor luminaires, buried enclosures, or wall-mount fixtures exposed to rain. The -40°C to +90°C operating range supports year-round outdoor use.
Can I use this driver for LED sign modules in a bus shelter or transit advertising display?
Yes. The constant current 1750mA output and IP67 enclosure are appropriate for transit advertising or bus shelter illuminated displays. The 100–305VAC input accommodates varying supply voltages across different sites, and the 5-year warranty reduces maintenance cost for hard-to-reach installations.
How many LEDs can be connected in series to the ELG-150-C1750DA?
The CC compliance range spans 43–86V. The number of series LEDs depends on each LED's forward voltage at 1750mA—you must divide the compliance window by the specific LED's Vf to determine viable string depth. A fixed LED count cannot be given because Vf varies across LED types and operating conditions.
Can this driver be used to retrofit an existing DALI-controlled downlight system?
Yes. The ELG-150-C1750DA is compatible with DALI (IEC 62386 edition 1) dimming protocols. If the existing system uses a standard DALI bus and controller, this driver can be added to the bus for addressable current-controlled LED loads within the 43–86V compliance range.
