Frequently Asked Questions
Can the ELG-100-C1050DA be integrated into a DALI lighting control system for smart building use?
Yes. The 'DA' suffix indicates a DALI-capable interface, allowing the driver to be controlled and addressed within a DALI digital lighting control network. This enables per-fixture dimming, scene recall, and fault monitoring from a DALI controller.
Is the ELG-100-C1050DA rated for outdoor use in wet environments?
Yes. The ELG-100-C1050DA carries an IP67 waterproof rating, making it suitable for outdoor luminaires and applications where the driver may be exposed to rain, splashing, or temporary water contact.
Can I use the ELG-100-C1050DA to power LED downlights in an office building with centralized dimming?
Yes. The DALI interface of this driver supports central dimming control from a building management system, making it practical for office environments that require zoned or scene-based lighting. It operates at 99.75W and 1050mA constant current.
What LED string forward voltage range is compatible with the ELG-100-C1050DA?
The CC output voltage range is 48–95V. LED series strings with a combined forward voltage within this window are compatible; the number of LEDs per series string depends on each LED's individual forward voltage specification.
Is the ELG-100-C1050DA suitable for LED signage in a retail environment that requires centralized brightness control?
Yes. DALI-based dimming allows a retail lighting controller to adjust the sign brightness by zone or schedule, and the constant current output ensures consistent LED brightness across the sign panel. The driver handles 99.75W across a 48–95V CC range.
How does the ELG-100-C1050DA compare to the ELG-100-C1050D2?
Both variants add digital dimming to the base ELG-100-C1050 platform at 99.75W / 1050mA / 48–95V CC. The ELG-100-C1050DA uses a DALI (version 1 compatible) interface, while the ELG-100-C1050D2 is certified to the newer DALI-2 standard, which adds stricter interoperability requirements. Both are rated IP67.
