Product Overview

The MEAN WELL HLG-480H series is a 480W AC-to-DC LED driver family featuring both constant-voltage (CV) and constant-current (CC) output modes. It is designed for LED port lighting, greenhouse lighting, stadium lighting, mining lighting, street lights, high-bay fixtures, and Class I Division 2 hazardous location luminaires.

It accepts universal 90~305VAC input (127~431VDC) and provides six fixed output voltage options: 24V, 30V, 36V, 42V, 48V, and 54V. With peak efficiency up to 95.5%, the driver uses a fanless design and operates at case temperatures from -40C to +90C under natural convection.

The metal enclosure carries IP67 or IP65 ratings depending on the version and is certified to UL8750 Type HL for Class I Division 2 hazardous location luminaires. Five function versions are available: Blank (fixed output, IP67), A (internal potentiometer adjustment, IP65), B (3-in-1 dimming, IP67), AB (pot adjustment + 3-in-1 dimming, IP65), and Dx (timing dimming, IP67).

Protection includes OVP, OTP (auto-recovery when temperature drops), short-circuit constant-current recovery, and over-current constant-current limiting. The driver withstands 4KV line-to-ground and 2KV line-to-line surge, complies with global lighting safety and EMC standards, and is backed by a 7-year warranty.

Frequently Asked Questions

What is the difference between HLG-480H and HLG-320H?

HLG-480H delivers up to 480W output compared to the 320W rating of HLG-320H, with higher output current on each voltage model. It shares the same CV+CC dual-mode design, IP67/IP65 sealing, Type HL certification, and 7-year warranty, but uses a larger 262 x 125 x 43.8mm enclosure and offers 24V-54V voltage options.

Can HLG-480H be used for direct LED drive?

Yes. Each voltage model has a specified constant-current range. If the LED string forward voltage falls within that range, the driver operates in constant-current mode. It can also power LED modules with built-in constant-current drivers in constant-voltage mode.

Which version type should I choose?

Blank for simple fixed-output outdoor luminaires. A-Type for fixtures needing voltage/current tuning via internal pot. B-Type for smart lighting with 0-10V/PWM/resistor dimming. AB-Type for maximum flexibility with both tuning and dimming. Dx-Type for timing dimming functions (contact MEAN WELL for details).

What IP rating do I get with each version?

Blank, B, and Dx versions are IP67. A and AB versions are IP65. A/AB types require internal use for Type HL applications. Refer to the datasheet for installation requirements.

Does HLG-480H support high ambient temperatures?

Yes. The driver operates at case temperatures from -40C to +90C with natural convection. For lifetime, MEAN WELL specifies >62,000 hours when Tcase remains below 75C.
