Information about the MEAN WELL HLG-240H-C1750A

The MEAN WELL HLG-240H-C1750A is a premier 250W AC/DC LED driver engineered for high-power constant current lighting solutions. This A-Type variant is distinguished by its heavy-duty aluminum enclosure with an IP65 rating, ensuring maximum protection against dust and water ingress in challenging indoor and outdoor environments. A core advantage of this model is the built-in internal potentiometer, which grants installers the flexibility to manually fine-tune the output current from 875 mA to 1750 mA, enabling perfect synchronization with specific LED array requirements and thermal management strategies. Achieving an efficiency of up to 93 %, the driver maintains a low thermal footprint, allowing for reliable fanless operation even at elevated case temperatures reaching +90 °C. The unit includes active Power Factor Correction (PFC) and is "Type HL" rated, making it safe for use in Class I, Division 2 hazardous locations such as industrial plants or refineries. Specifically designed for LED street lighting, high-bay architectural fixtures, and fishing lamps, its robust design is validated by a typical lifetime of more than 62,000 hours and is supported by a comprehensive 7-year manufacturer warranty, representing a top-tier choice for long-term infrastructure reliability.
