Product Overview

The MEAN WELL HLG-320H-C series is a 320W AC-to-DC constant-current (CC) LED driver family with Type HL certification for Class I, Division 2 hazardous location lighting. It is designed for LED street lighting, fishing lamps, harbor lighting, building architectural lighting, greenhouse lighting, and bay lighting.

It accepts universal 90~305VAC input (127~417VDC) and provides seven fixed output current options: 700mA, 1050mA, 1400mA, 1750mA, 2100mA, 2800mA and 3500mA. With peak efficiency up to 94%, the driver uses a fanless design and operates at case temperatures from -40C to +85C under free air convection.

The metal enclosure carries IP67 or IP65 ratings depending on the version. Five function versions are available: A (output current adjustable via built-in potentiometer, IP65), B (3-in-1 dimming, IP67), AB (current adjustment + 3-in-1 dimming, IP65), DA (DALI control, IP67), and Dx (smart timer dimming functions, IP67, customer-specific - contact MEAN WELL for details).

Protection includes OVP (shutdown with re-power recovery), OTP (automatic recovery after temperature drops), and short-circuit constant-current limiting with automatic recovery. The driver complies with global lighting safety and EMC standards including UL8750 Type HL, CSA, IEC/AS/NZS/GB, and EAC, and is backed by a 7-year warranty. Note: a switch must be installed between the mains and the LED driver to meet the latest ErP regulations.

Frequently Asked Questions

What is the difference between HLG-320H-C700, C1050, C1400, C1750, C2100, C2800 and C3500?

The model number indicates the rated constant current: C700=700mA, C1050=1050mA, C1400=1400mA, C1750=1750mA, C2100=2100mA, C2800=2800mA, C3500=3500mA. Each model has a different output voltage region matched to the current. C700 covers 214~428V; C1050 covers 152~305V; C1400 covers 114~229V; C1750 covers 91~183V; C2100 covers 76~152V; C2800 covers 57~114V; C3500 covers 46~91V. All share the same 320W-class enclosure, protection, and certification set.

Is HLG-320H-C a constant-voltage driver?

No. HLG-320H-C is a constant-current LED driver. It maintains a fixed output current while the output voltage varies within the specified constant-current region based on the LED load. Do not use it to power LED modules that require a constant-voltage supply.

Which version type should I choose?

A-Type for fixtures needing current tuning via internal potentiometer. B-Type for smart lighting with 0-10V/PWM/resistor dimming. AB-Type for both tuning and dimming. DA-Type for DALI digital control. Dx types for smart timer dimming functions - contact MEAN WELL because these are customer-specific programs.

What IP rating do I get with each version?

B, DA and Dx versions are IP67. A and AB versions are IP65. Select IP67 for direct outdoor exposure and IP65 for protected outdoor or indoor applications.

What does Type HL certification mean?

HLG-320H-C is listed as UL8750 Type HL, which means it is suitable for use in Class I, Division 2 hazardous location lighting fixtures when installed according to the applicable codes and manufacturer instructions.
