Frequently Asked Questions
What does the 'DA' suffix mean on the ELG-75-48DA, and how is it different from the 'B' type?
The 'DA' suffix indicates the ELG-75-48DA includes a DALI (Digital Addressable Lighting Interface) dimming interface, which is a digital protocol widely used in commercial building automation. Unlike the 'B' type which accepts analog 0–10V or PWM signals, the DA type communicates over a two-wire DALI bus, enabling addressable and group-based control.
Can the ELG-75-48DA be integrated into a DALI-based building management system for 48V LED lighting?
Yes, the ELG-75-48DA is designed for DALI systems. It can be addressed and controlled individually or as part of a group via a DALI controller or BMS, allowing scene recall, occupancy-based dimming, and daylight harvesting for 48V LED installations up to 76.8W.
Is the ELG-75-48DA suitable for outdoor DALI-controlled LED signage or architectural lighting?
Yes. The ELG-75-48DA carries an IP67 rating, so it withstands dust and temporary water immersion, making it suitable for outdoor architectural lighting and signage that requires DALI control. Its -40°C to +85°C operating range supports year-round outdoor deployment.
How many meters of 48V LED strip can the ELG-75-48DA power?
The ELG-75-48DA delivers up to 76.8W at 48V and 1.6A. For a 48V strip rated at 10W/m, this supports approximately 7.6 meters (76.8W ÷ 10W/m ≈ 7.6m). Check your specific strip's rated power per meter and keep total load under 76.8W.
Can the ELG-75-48DA be used in a DALI-controlled 48V LED troffer or luminaire in a commercial office?
Yes, the ELG-75-48DA is well-suited for commercial office luminaires requiring DALI control. At 76.8W, 48V, and 1.6A, it can drive a 48V LED engine within a troffer or recessed fixture, and its DALI interface enables digital dimming and group addressing consistent with EN 62386 systems.
Does the ELG-75-48DA work in cold outdoor climates for DALI-controlled landscape lighting?
Yes. The ELG-75-48DA operates down to -40°C and is IP67-rated, making it appropriate for cold-climate outdoor landscapes where DALI control is needed for automated dimming at different times of night or seasonal schedules.
Can the ELG-75-48DA replace a non-DALI driver in an existing 48V lighting retrofit?
The ELG-75-48DA outputs 48V at up to 1.6A constant current (76.8W), so it can replace a non-DALI driver with matching voltage and power ratings. Adding the DALI interface requires a DALI controller or bus already present in the circuit; if no DALI infrastructure exists, a simpler 'A' or 'B' type driver may be more appropriate.
