Page 89 MEAN WELL LED DRIVER CATALOG

As increases in energy costs and demands to reduce fossil-based emissions are accelerating a worldwide call for clean energy
and efficient power consumption, the DC House is far beyond a concept but necessary infrastructure. MEAN WELL is proud to
introduce a new DC centralized bus for indoor device applications to reduce power loss issue

With nearly four decades of experience in power supply design and manufacturing, MEAN WELL provides power solutions for DC
centralized bus and DC lighting applications with complete enclosed type and DC to DC LED driver product portfolios. The DC
centralized bus is easily integrated into a renewable energy system to reduce power consumption and total cost.
