Frequently Asked Questions

Is the ELG-150-48DA rated for outdoor use in wet conditions?

Yes. The ELG-150-48DA has an IP67 waterproof rating, providing full protection against dust ingress and temporary submersion in water. It is suitable for outdoor luminaires, buried-conduit systems, and any installation where direct moisture contact is possible.

How long a 48V LED strip run can the ELG-150-48DA support?

The ELG-150-48DA outputs 150.2W at 48V. Dividing by rated strip wattage per meter: a 10 W/m strip supports up to about 15 meters; a 15 W/m strip supports up to about 10 meters. Check your strip's rated power per meter and apply a 20% derating for thermal safety.

Can the ELG-150-48DA be used to power 48V LED strips in a hotel lobby with DALI control?

Yes. The DA suffix designates DALI dimming capability, which is compatible with the DALI lighting control protocols used in commercial hospitality installations. At 150.2W and 48V, it comfortably drives the LED strip loads typical of lobby cove or feature lighting.

Is the ELG-150-48DA appropriate for outdoor LED architectural uplighting on building facades?

Yes. Its IP67 rating and -40°C to +90°C operating temperature make it durable in year-round outdoor facade applications. The 48V output is advantageous for longer cable runs to facade-mounted LED strips or fixtures, reducing resistive voltage drop compared to 24V systems.

What certifications does the ELG-150-48DA hold, and is it approved for use in Asia-Pacific markets?

The ELG-150-48DA is certified to c_bsi, CB, CCC, CE, EAC, ENEC, KC, c_rcm, and UL. The c_rcm mark covers Australia and New Zealand, CCC covers China, and KC covers South Korea, confirming broad Asia-Pacific market approval in addition to North American and European certifications.

How does the ELG-150-48DA compare to the ELG-150-48D2 for DALI-controlled 48V LED lighting?

Both are 48V, approximately 150W, and 3.13A with IP67 protection and DALI dimming. The ELG-150-48D2 (150W) has a CC voltage range of 100–305V and carries BSMI, CB, CE, EAC, and UL certifications. The ELG-150-48DA (150.2W) has a narrower CC range of 24–48V and adds c_bsi, CCC, ENEC, KC, and c_rcm certifications for wider international approval.
