MEAN WELL HLG-120H-48B 120W 48V LED Driver IP67 3-in-1 Dimmable Constant Voltage & Constant Current Power Supply

The HLG-120H-48B provides a rated 48V output with a 2.5A maximum/rated current, while its constant-current operating region extends from approximately 24V to 48V. This makes it more technically accurate to describe the product as a 120W 48V CC/CV LED driver, rather than simply a fixed-voltage 48V power supply.The driver accepts a wide 90–305VAC input range, incorporates active PFC, uses a fanless metal housing with natural convection cooling, and carries an IP67 protection rating for indoor and outdoor installations. The HLG-120H series is designed for applications including LED street lighting, LED high-bay lighting, parking-area lighting, greenhouse lighting and other professional LED systems.

• Constant voltage + constant current mode output
• The HLG-120H series uses free-air convection instead of a mechanical cooling fan, eliminating a moving cooling component and allowing the driver to operate without fan noise or fan-maintenance requirements
• The driver incorporates protection against short circuit, over-current, over-voltage and over-temperature conditions, providing an additional level of electrical protection for the LED driver and connected lighting system when abnormal operating conditions occur
• IP67/IP65 rating for indoor or outdoor installations
• The B-type version includes 3-in-1 dimming, supporting 1–10VDC, PWM signal and resistance control
• MEAN WELL specifies a typical lifetime of more than 62,000 hours for the HLG-120H series under its specified conditions, supporting applications where long operating periods and reduced maintenance requirements are important.
• 7 years warranty

What protection functions should buyers confirm?
Buyers should confirm short-circuit, overload, overvoltage, and over-temperature protection, as well as the fault-recovery method. For outdoor or infrastructure projects, surge-protection capability should also be verified according to the project requirement.

Can the factory provide samples?
Samples are usually available for checking dimensions, mounting method, optical performance, and luminaire compatibility. Sample policy depends on the project and order quantity.

What are the typical MOQ and lead time?
MOQ and lead time depend on whether the product is standard or customized. Standard versions usually have shorter lead times, while custom models require confirmation based on tooling, testing, and production scheduling.
