Frequently Asked Questions
Can the ELG-100-42DA be integrated into a DALI lighting control network?
Yes. The ‘DA’ suffix designates DALI dimming capability. The ELG-100-42DA accepts a DALI control signal, allowing it to be addressed individually within a DALI network for scene control, dimming scheduling, and fault reporting in commercial or architectural lighting systems.
Is the ELG-100-42DA suitable for outdoor LED installations requiring DALI control?
Yes. The driver is rated IP67 waterproof, meaning it is fully sealed against dust and water immersion up to 1 metre. This allows outdoor mounting for DALI-controlled LED luminaires on building facades, in landscape settings, or in other wet-exposed locations.
Can I use the ELG-100-42DA for a DALI-controlled LED strip run in a commercial office or retail space?
Yes. The 95.76W / 42V output and DALI control interface make the ELG-100-42DA suitable for DALI-dimmed 42V LED strip systems in offices, retail, or hospitality environments. For strip rated at 10W per meter, the driver supports up to approximately 9.5 meters per circuit—verify your strip’s power density.
Can the ELG-100-42DA be used to drive 42V LED luminaires in a DALI-2 compliant building automation system?
The ELG-100-42DA supports the DALI interface for dimming control. Verify with the product datasheet or supplier whether the specific firmware version meets DALI-2 certification requirements for your building automation project, as DALI and DALI-2 compatibility can vary by revision.
How does the ELG-100-42DA compare to the ELG-100-42AB for a controllable LED lighting system?
Both deliver 95.76W at 42V with 2.28A output current. The ELG-100-42AB offers 3-in-1 dimming (1–10V / PWM / resistance) plus output voltage adjustment and is rated IP65. The ELG-100-42DA provides DALI dimming (suitable for addressable DALI networks) and is rated IP67. Choose the ‘AB’ for analogue or PWM dimming systems; choose the ‘DA’ for DALI-bus control.
Will the ELG-100-42DA operate at extreme cold temperatures in outdoor winter conditions?
Yes. The ELG-100-42DA is rated for -40°C to +90°C operation. This covers cold-climate outdoor installations in northern regions where temperatures regularly drop well below freezing.
