Information about the MEAN WELL HLG-240H-C1050A

The MEAN WELL HLG-240H-C1050A is a high-performance 250W AC/DC LED driver designed for high-voltage, constant current architectural and industrial lighting systems. This A-Type model is characterized by its IP65-rated aluminum housing, which ensures reliable protection against dust and moisture ingress, making it a perfect fit for rugged indoor and outdoor installations. A key technical advantage is the built-in potentiometer, which enables installers to manually fine-tune the output current from 525 mA to 1050 mA, providing the flexibility needed to match specific LED string requirements. Delivering a peak efficiency of 94 %, the unit minimizes thermal loss, supporting fanless operation through free air convection even in extreme environmental conditions up to a +90 °C case temperature. Its advanced design includes active Power Factor Correction (PFC) and complies with "Type HL" standards for use in hazardous (Classified) locations. With a proven lifetime of over 62,000 hours and an industry-standard 7-year manufacturer warranty, the HLG-240H-C1050A offers a highly dependable and cost-effective solution for LED street lighting, high-bay fixtures, and large-scale architectural illumination.
