Information about the MEAN WELL HLG-240H-54
The MEAN WELL HLG-240H-54 is the high-voltage specialist within the 240W family. Delivering a stable 54V output, it is perfectly suited for specialized industrial equipment, high-voltage LED arrays, and serving as a high-quality charger for 48V battery systems that require a boost charge voltage of up to 58V (available via A-type adjustment). Boasting a peak efficiency of 94%, the driver minimizes thermal loss, allowing for a completely silent, fanless operation even in environments where case temperatures reach +90 °C. The unit's dual-mode output provides flexibility by automatically transitioning between constant voltage and constant current modes based on the load. Its Type HL certification ensures safety in Class I, Division 2 hazardous locations. With its ruggedized metal construction and an industry-leading 7-year warranty, the HLG-240H-54 remains a top-tier choice for critical infrastructure, telecommunications, and heavy-duty outdoor lighting.
