Frequently Asked Questions
Is the ELG-240-C1750DA compatible with DALI building automation systems?
Yes. The DA suffix indicates a built-in DALI (Digital Addressable Lighting Interface) dimming input. The driver can be addressed and dimmed directly from a DALI controller on a shared two-wire bus, enabling integration with building management systems and scene-based lighting control in commercial or institutional LED downlight installations.
Can the ELG-240-C1750DA be used in outdoor LED signage where rain exposure is a concern?
Yes. The IP67 waterproof rating means the driver is sealed against dust and can withstand temporary water immersion, making it suitable for outdoor sign enclosures exposed to rain or high-pressure cleaning. The -40°C to +85°C operating range also supports outdoor deployment in most climates.
What LED load voltage range works with this driver?
The ELG-240-C1750DA is a constant current driver delivering 1750mA; its output voltage self-adjusts between 69V and 137V to maintain that current. The number of LEDs that can be connected in series depends on each LED's forward voltage, provided the total string voltage falls within 69–137V.
Is this driver suitable for powering high-power LED arrays in a sports or industrial facility?
Yes. At 239.75W and 1750mA with IP67 sealing and a broad operating temperature range, the ELG-240-C1750DA can drive the high-power LED arrays found in sports hall floodlights or industrial high-bay luminaires, particularly where DALI dimming is required for energy management or occupancy-based control.
How does the DALI variant compare to the standard ELG-240-C1750 without a dimming interface?
Both the ELG-240-C1750 and ELG-240-C1750DA share the same power (239.75W), current (1750mA), CC voltage range (69–137V), IP67 rating, and certifications. The key difference is that the DA variant includes a DALI-2 compatible dimming input for digital bus control, whereas the base model has no dimming capability.
Can I install the ELG-240-C1750DA in a humid or tropical outdoor environment?
Yes. The IP67 rating protects against moisture ingress and the driver is rated to operate at temperatures up to +85°C, which accommodates the high ambient temperatures found in tropical regions. The metal enclosure and wide certification portfolio (CB, CE, UL, and others) further support deployment in international markets with challenging climates.
