Frequently Asked Questions
What does the 3Y suffix mean on the ELG-240-48DA-3Y?
The 3Y suffix indicates this model accepts a three-wire input configuration. This is relevant for installations where a neutral wire is available alongside line and ground, as found in many European and industrial wiring standards.
Does the ELG-240-48DA-3Y support DALI dimming?
Yes. The DA portion of the SKU indicates DALI dimming support, allowing the driver to be addressed and dimmed through a DALI bus. This is useful for smart building projects, office lighting systems, and any installation requiring networked dimming control.
Is the ELG-240-48DA-3Y rated for outdoor use?
Yes. The IP67 rating means the enclosure is fully sealed against dust and protected against temporary water immersion, making it suitable for outdoor LED architectural lighting, signage enclosures, and installations exposed to rain.
How many meters of 48V LED strip can the ELG-240-48DA-3Y power?
With 240W output at 48V, this driver supports up to 240W of LED load. At a strip density of 20W per meter, that is 12 meters; at 16W per meter it is 15 meters. Always verify the strip's per-meter wattage and do not exceed 240W total.
Can the ELG-240-48DA-3Y be used in commercial office LED lighting systems with a building automation controller?
Yes. DALI compatibility and a three-wire input make this driver well suited for commercial office LED luminaires connected to DALI-enabled building automation or energy management systems. The 240W capacity at 48V can drive substantial LED loads from a single driver.
What operating temperature range does the ELG-240-48DA-3Y support?
The driver operates reliably from -40°C to +90°C, covering extreme cold outdoor environments as well as warm enclosed fixture housings. This wide range makes it viable in both northern climate outdoor installations and high-ambient industrial settings.
