Frequently Asked Questions
Can I use the ELG-100-C350DA in a DALI-controlled office lighting system with LED downlights?
Yes. The DA suffix designates native DALI dimming support, allowing this driver to receive commands from a DALI bus controller. It delivers a constant 350mA across a CC voltage range of 143–286V, making it suitable for the high-voltage LED arrays commonly used in commercial downlight luminaires.
Is the ELG-100-C350DA suitable for LED signage modules installed outdoors?
Yes. The driver has an IP67 waterproof rating and operates across an input range of 100–305VAC, accommodating worldwide mains. Its constant current output of 350mA maintains stable LED brightness even as ambient temperature varies from -40°C to +90°C, which is important for outdoor sign reliability.
What is the benefit of DALI dimming on the ELG-100-C350DA compared to standard analog dimming?
DALI (Digital Addressable Lighting Interface) allows individual addressing of luminaires on a shared bus, enabling precise, digital control of each fixture independently. This is advantageous in smart building systems where zone-by-zone or fixture-by-fixture dimming is required, compared to analog 1–10V dimming which typically controls groups of drivers.
How many LEDs can I string together with the ELG-100-C350DA?
The ELG-100-C350DA operates with a CC voltage range of 143–286V. The exact number of LEDs that fit in a series string depends on the forward voltage of each LED used — divide the available voltage range by the LED's forward voltage to determine compatible string lengths. The driver will regulate at a constant 350mA throughout.
Does the IP67 rating on the ELG-100-C350DA allow installation inside a sealed outdoor fixture housing?
Yes. IP67 indicates complete protection against dust ingress and resistance to temporary submersion in water. This makes the ELG-100-C350DA suitable for installation inside sealed outdoor luminaire housings, even in environments subject to rain, humidity, or occasional water exposure.
