Meanwell Power Supply ELG-150-48DA-3Y 150W 48V IP67 DALI Dimmable

The Mean Well ELG-150-48DA-3Y is a high-performance 150W AC/DC LED power supply designed for professional lighting installations. Delivering a constant voltage output of 48V at 3.13A, this driver supports dual operating modes — constant current and constant voltage — combined with a DALI dimmable function for precise and digital light level control.

With a fanless aluminum housing and an efficiency of up to 91%, the ELG-150-48DA-3Y is built for reliable long-term use in architectural, commercial and residential lighting projects, both indoors and outdoors. Universal input voltage compatibility (100-240V AC) makes it suitable for installations across EU, USA, UK, Australia and Japan.

Key technical features

The power supply operates across a wide temperature range from -40°C to +90°C under free air convection, with no need for forced cooling. Its compact footprint of 219 x 63 x 35 mm simplifies integration into tight spaces. DALI dimming enables full compatibility with modern building automation and smart lighting control systems.

Safety and protection

The IP67 ingress protection rating ensures complete dust-tight sealing and resistance to temporary water immersion, making this unit fully suitable for exposed outdoor environments. The rigid aluminum metal enclosure provides structural durability and efficient passive thermal dissipation.

Applications

Perfectly suited for LED lighting systems in commercial, retail, museum, architectural and outdoor settings where DALI-controlled dimming and stable 48V power delivery are essential requirements.
