Frequently Asked Questions
Can the ELG-240-C1050DA be used for DALI-controlled LED downlights in a building management system?
Yes. The 'DA' suffix indicates native DALI (Digital Addressable Lighting Interface) dimming support, making this driver directly compatible with DALI-based building management and lighting control systems. It delivers 1050mA constant current with output voltages in the 114–228V range.
Is the ELG-240-C1050DA suitable for use in damp or outdoor locations?
Yes. With an IP67 rating, the driver is protected against temporary water immersion and can be installed in outdoor enclosures, damp ceilings, or architectural lighting fixtures exposed to moisture. Its operating range extends from -40°C to +85°C.
Can this driver power LED modules in a DALI-networked signage installation?
Yes. The DALI interface allows individual addressing and scene control of connected LED modules. At 239.4W and 1050mA constant current across 114–228V, it can sustain a large series string of sign modules while supporting DALI group commands and dimming schedules.
How does the DALI dimming on the ELG-240-C1050DA differ from 0–10V dimming on the ELG-240-C1050B?
The ELG-240-C1050DA uses the DALI digital protocol, which allows individual driver addressing, scene storage, and two-way status feedback over a two-wire bus. The ELG-240-C1050B uses analogue 0–10V or PWM dimming, which requires a separate analogue control signal per driver or zone and does not support individual addressing.
How many LEDs can I run from the ELG-240-C1050DA?
The driver outputs a constant 1050mA and regulates output voltage across 114–228V. The number of LEDs in the series string depends on the forward voltage of each individual LED — divide the usable voltage range by your LED's Vf to determine the feasible string length.
Can this driver withstand installation in a rooftop or parking structure exposed to temperature extremes?
Yes. The ELG-240-C1050DA operates across -40°C to +85°C and is IP67-rated for water immersion, making it suitable for rooftop, parking structure, and other harsh-environment LED installations where temperature swings and moisture exposure are expected.
