Frequently Asked Questions
Can the ELG-200-C2100DA be used for DALI-controlled LED downlights in a smart building?
Yes. The DA suffix indicates this model supports the DALI dimming protocol, enabling integration with DALI-compliant building automation and lighting management systems. At 201.6W and 2100mA constant current, it is well suited to driving LED downlight arrays in smart offices, hotels, or retail environments.
Is the ELG-200-C2100DA appropriate for outdoor LED luminaires in street or pathway lighting?
Yes. With an IP67 waterproof rating and an operating temperature range of -40°C to +85°C, the ELG-200-C2100DA handles the environmental stresses of outdoor street and pathway luminaire applications. The 100–305VAC wide input also accommodates international mains voltages.
Can this driver power LED arrays in architectural facade lighting controlled by a DALI system?
Yes. The DALI dimming interface on the ELG-200-C2100DA allows dimming commands from a DALI controller to adjust output across the LED load. The 201.6W output at 2100mA with a 48–96V CC voltage range is sufficient for high-power LED arrays used in facade wash and architectural accent lighting.
What is the CC voltage range of the ELG-200-C2100DA and how should LED strings be sized?
The ELG-200-C2100DA operates as a constant current source with an output voltage that self-adjusts within 48–96V. LED strings should be designed so the total combined forward voltage of all series LEDs falls within this 48–96V window; the exact number of LEDs depends on each LED's individual forward voltage.
How does the ELG-200-C2100DA differ from the ELG-200-C2100D2 in terms of dimming protocol?
The ELG-200-C2100DA uses the DALI protocol (standard DALI), while the ELG-200-C2100D2 uses the DALI-2 protocol. Both operate at 201.6W with 2100mA constant current and a 48–96V CC voltage range, but differ in the specific DALI version they support; DALI-2 introduces stricter device certification and bidirectional communication requirements compared to original DALI.
Can the ELG-200-C2100DA operate reliably in humid or wet outdoor environments?
Yes. The IP67 rating confirms full dust exclusion and protection against temporary water immersion. Combined with the -40°C to +85°C operating temperature range, the ELG-200-C2100DA is rated for demanding outdoor and semi-outdoor installations where moisture and temperature cycling are present.
