Information about the MEAN WELL HLG-120H-54A
The MEAN WELL HLG-120H-54A is a professional-grade 120W LED driver and power supply engineered for industrial durability and precise power management. As an "A-Type" model, it is specifically designed for on-site hardware calibration. It features two internal potentiometers located under protective rubber stoppers on the rugged metal enclosure, allowing installers to manually fine-tune the output voltage from 49V to 58V and calibrate the current limit from 1.15A to 2.3A.
Operating in dual-mode constant voltage and constant current, the HLG-120H-54A ensures stable performance across various load configurations. Its IP65-rated aluminum housing provides robust protection against environmental ingress such as dust and water splashes. The fanless thermal design utilizes natural air convection for cooling, ensuring completely silent operation and a long operational lifespan exceeding 62,000 hours.
With a peak efficiency of 93% and built-in active PFC, the driver minimizes energy waste and optimizes power quality. It includes comprehensive safety mechanisms, including short circuit, overvoltage, and overtemperature protections. Backed by a 7-year manufacturer warranty and carrying the "Type HL" rating for hazardous locations, this driver is a premier choice for PoE power systems, high-voltage lighting arrays, and industrial communication equipment.
