FAQ

What dimming interface does the ELG-150-24DA-3Y provide for LED strip control?

The DA suffix indicates a DALI (IEC 62386) digital dimming interface. The driver can be individually addressed on a shared DALI bus (16 groups, 64 addresses) and dimmed from 100% down to a first step of about 8% via a DALI controller, suitable for lighting systems that require scene programming or energy management control.

Can the ELG-150-24DA-3Y be used for 24V LED cove lighting in a DALI-controlled hotel or hospitality venue?

Yes. Hotel and hospitality cove lighting is a common application for DALI-dimmable 24V drivers. The ELG-150-24DA-3Y can be addressed individually on the DALI bus and delivers up to 150W to 24V LED strips, sufficient for medium-to-long cove runs with smooth dimming capability.

Is the ELG-150-24DA-3Y weatherproof enough for outdoor architectural lighting with DALI control?

Yes. The IP67 rating means the driver is sealed against dust and temporary water immersion, allowing placement in outdoor luminaire housings or enclosures exposed to rain. The -40°C to +90°C case temperature (Tcase) range covers outdoor temperature extremes in most regions.

How many meters of 24V, 16.8 W/m LED strip can the ELG-150-24DA-3Y run?

At 150W maximum output, dividing by 16.8 W/m gives approximately 8.9 m of strip (150 ÷ 16.8). For a 12 W/m strip, that extends to about 12.5 m (150 ÷ 12). Always verify the strip's rated power per meter and stay within the 150W limit.

Can the ELG-150-24DA-3Y be used to drive 24V LED strips in museum display cases where smooth, flicker-free dimming is required?

It can provide smooth DALI-controlled dimming down to a minimum of about 8% output for museum displays. The sheet does not specify flicker performance, so confirm flicker requirements with the LED strip and system supplier before specifying it for critical display environments.

Does the ELG-150-24DA-3Y accept both 120V and 230V mains input?

Yes. The input accepts 100–305VAC with no manual switching, making the ELG-150-24DA-3Y compatible with 120V North American, 230V European, and 277V commercial supplies from a single SKU.
