Frequently Asked Questions
Can the ELG-75-36DA be used in a DALI building management system?
Yes. The 'DA' suffix denotes DALI dimming support, allowing the driver to accept DALI bus commands from a DALI controller or building management system. This makes it suitable for commercial spaces where centralized lighting control and scene management are required.
Is the ELG-75-36DA waterproof enough for outdoor LED signage?
Yes. The ELG-75-36DA is rated IP67, providing full dust protection and resistance to temporary water immersion. It can be mounted inside outdoor sign cabinets or landscape lighting enclosures where rain and moisture are present.
How many meters of 36V LED strip can the ELG-75-36DA support?
The ELG-75-36DA delivers 75.6W at 36V. For a 10 W/m LED strip, maximum length is approximately 7.5 meters; for a 15 W/m strip, about 5 meters. Divide 75.6W by your strip's rated wattage per meter, then derate by 20% for a safe operating margin.
Can I use the ELG-75-36DA for architectural lighting in a hotel lobby?
Yes. With DALI dimming, 75.6W at 36V, and a wide 100–305VAC input, this driver suits premium hospitality installations where smooth dimming and scene control via a DALI network are expected. Its -40°C to +85°C range also accommodates demanding in-ceiling thermal environments.
Is the ELG-75-36DA suitable for powering 36V LED strips in retail display lighting?
Yes. The constant-current 36V output and DALI dimming capability make the ELG-75-36DA a good fit for retail display cases and accent lighting where precise, digitally controlled dimming levels are needed. The IP67 rating adds protection in environments with cleaning sprays or humidity.
What is the difference between the ELG-75-36DA and the ELG-75-36D2?
Both use DALI dimming, but the 'D2' suffix indicates DALI 2 (second-generation protocol with two-way communication and enhanced device type support), while the 'DA' uses the original DALI protocol. The ELG-75-36DA is rated 75.6W; check your DALI controller compatibility to choose the correct generation for your system.
