Information about the MEAN WELL HLG-120H-24A
The MEAN WELL HLG-120H-24A is a high-performance 120W LED driver, widely regarded as a staple for 24V professional lighting systems. As an "A-Type" model, it is specifically designed for on-site customization. It features two internal potentiometers located under protective rubber stoppers, allowing installers to manually fine-tune the output voltage from 22V to 27V and calibrate the current limit from 2.5A to 5A to perfectly match the connected load.
The unit operates in dual-mode constant voltage and constant current, providing exceptional stability whether it is powering 24V LED strips or direct COB LED arrays. Housed in a rugged IP65-rated aluminum enclosure, the HLG-120H-24A is built to withstand dust and moisture ingress, making it suitable for high-bay lighting, urban street lamps, and outdoor architectural accentuation. The fanless design ensures silent operation and efficient cooling through natural air convection.
With a peak efficiency of 93% and built-in active PFC, the driver minimizes energy waste and optimizes power factor. It includes comprehensive safety mechanisms, such as short circuit, overcurrent, 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 mission-critical infrastructure and large-scale industrial projects.
