Mean well 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 digital control of light levels.

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. Its compact footprint of 219 x 63 x 35 mm simplifies integration into tight spaces, while DALI dimming ensures full compatibility with modern building automation and smart lighting control systems. The IP67 ingress protection rating guarantees complete dust-tight sealing and resistance to temporary water immersion, making this unit fully suitable for exposed outdoor environments. The rigid aluminum enclosure provides structural durability and efficient passive thermal dissipation, with no need for forced cooling.
