Frequently Asked Questions
Can I use the ELG-240-C1400DA to drive LED downlights in a commercial building?
Yes. The ELG-240-C1400DA delivers a constant 1400mA across a CC voltage range of 86–171V, making it well suited for series strings of high-power LED downlights used in commercial or retail spaces. Its IP67 waterproof rating also allows installation in ceiling voids or damp service areas.
Is the ELG-240-C1400DA suitable for outdoor LED signage?
Yes. The IP67 rating means the driver is fully sealed against dust and sustained water immersion, so it can be mounted inside outdoor sign cabinets exposed to rain or high humidity. The operating temperature range of -40°C to +85°C ensures reliable operation in most outdoor climates.
Can this driver power LED arrays installed in wet or washdown environments?
Yes. The IP67 enclosure protects the ELG-240-C1400DA against temporary submersion, so it is appropriate for wet-location LED arrays such as those used in food-processing facilities, car washes, or covered outdoor walkways rated for water exposure.
What LED load voltage range is compatible with this driver?
The ELG-240-C1400DA operates in constant current mode and its output voltage adjusts automatically between 86V and 171V to maintain a steady 1400mA output. The number of LEDs you can connect in series depends on the forward voltage of each LED; the driver will regulate current as long as the combined string voltage falls within that 86–171V window.
How does DALI dimming work on the ELG-240-C1400DA?
The DA suffix indicates built-in DALI (Digital Addressable Lighting Interface) dimming. A DALI controller on the same two-wire bus can dim this driver from 100% down to low levels, enabling scene control and integration with building automation systems without additional dimming hardware.
Can the ELG-240-C1400DA be used in cold-storage or freezer lighting applications?
Yes. The driver is rated for operation down to -40°C, which covers standard commercial freezer and cold-room temperatures. Combined with the IP67 sealing, it is a practical choice for LED fixtures installed inside refrigerated warehouses or blast-freeze tunnels.
How does the ELG-240-C1400DA compare to other 240W constant-current variants in the ELG-240 family?
Within the ELG-240 CC range, the C700 variant outputs 700mA, C1050 outputs 1050mA, C1400 outputs 1400mA, C1750 outputs 1750mA, and C2100 outputs 2100mA — all at roughly 240W. The C1400DA specifically adds DALI dimming and carries an IP67 rating; other suffix variants offer different control options such as adjustable output (A), analog/PWM dimming (B), or D2 dimming.
