Information about the MEAN WELL SLD-50-56
The MEAN WELL SLD-50-56 is a high-voltage specialized LED driver featuring an ultra-slim linear design with a height of only 16.8mm, making it the ideal choice for modern linear luminaires and slim troffer lighting. This model is specifically engineered to handle higher voltage requirements while maintaining a dual-mode Constant Voltage and Constant Current output, providing maximum flexibility for professional lighting installations. With an impressive efficiency of up to 90%, the unit operates reliably under natural convection cooling, which eliminates the need for noisy fans and significantly reduces the overall thermal footprint within tight mounting spaces.
In addition to its compact form factor, the SLD-50-56 excels in performance with a wide input range of 110 to 305VAC and an integrated active PFC function for superior power quality. It is designed as a Class 2 power unit and features comprehensive safety protocols, including short circuit, over-voltage, and over-temperature protection with automatic recovery. This driver is particularly optimized for signage, cove lighting, and decorative lighting applications where high-voltage stability and a low-profile aesthetic are required. Its hiccup mode protection and robust housing ensure long-term durability and consistent performance in demanding commercial environments.
