Detailed Information on the MEAN WELL XLG-50-H-DA2

The MEAN WELL XLG-50-H-DA2 is a high-performance 50W AC/DC LED driver engineered with a sophisticated Constant Power Mode architecture. This specific "H" type model is optimized for lower voltage, higher current LED configurations, offering a constant current region between 27V and 56V. A primary strength of this unit is its integration of the latest DALI-2 dimming protocol, supporting Device Type 6 (DT6) for precise, flicker-free light control down to a minimum level of 8%. The driver provides exceptional design flexibility through its adjustable output current, which can be tuned between 500mA and 1400mA via the built-in potentiometer to match specific luminaire requirements. Built for longevity in demanding environments, the device features a rugged metal housing and an IP67 ingress protection rating, ensuring reliable operation in both indoor and outdoor settings such as street lighting and architectural floodlighting. Reliability is further enhanced by 6KV surge immunity and a specialized Input Over Voltage Protection capable of surviving 440VAC stress for 48 hours. With an efficiency reaching 90% and a wide operating temperature range of -40°C to +85°C, this driver ensures a typical lifetime of over 50,000 hours, providing a stable and energy-efficient power solution for modern industrial lighting systems.
