Information about the MEAN WELL HLG-240H-42A

The MEAN WELL HLG-240H-42A is a high-performance 240W AC/DC LED driver renowned for its industrial durability and manual adjustability. This A-type model features built-in potentiometers, allowing technicians to manually fine-tune the output voltage and current levels to match specific 42V LED module requirements or compensate for voltage drops in complex wiring layouts. Operating with a sophisticated dual-mode constant voltage and constant current strategy, it ensures exceptional electrical stability and long-term protection for high-power LED arrays. The rugged metal housing is IP65-rated, making it highly resistant to dust and moisture, which is ideal for industrial high-bay fixtures, parking area illumination, and horticultural grow lights. With a peak efficiency of 93.5% and a specialized fanless thermal design, the driver operates silently and reliably even in harsh environments at case temperatures up to +90 °C. Furthermore, its Type HL certification qualifies it for use in Class I, Division 2 hazardous locations. Backed by an industry-leading 7-year warranty, the HLG-240H-42A provides a robust and maintenance-free power solution for critical large-scale projects.
