MEAN WELL HLG Series Premium Metal-Case LED Drivers
The HLG series is MEAN WELL's flagship and most prestigious LED driver family. Renowned globally for its uncompromised quality and extreme reliability, it features a Constant Voltage + Constant Current (CV+CC) dual-mode output, making it the ultimate choice for the most demanding, mission-critical indoor and outdoor lighting applications.
- Premium Reliability: Built with the highest-grade components, the HLG series boasts an exceptionally long lifespan and is backed by an industry-leading 7-year manufacturer warranty.
- Dual-Mode Output: Flexibly operates in Constant Voltage mode for powering LED strips and signage, or Constant Current mode for directly driving high-power LED arrays.
- Rugged Aluminum Housing: Features a robust Class I metal enclosure with a functional ground, completely potted with heat-conducting silicone for superior thermal management and IP65/IP67 environmental protection.
- Extreme Temperature Tolerance: Capable of operating flawlessly in harsh environments ranging from extreme cold to high-heat industrial ceilings (typically -40°C to +90°C case temperature).
Technical Highlights
- Wide Input Range: Supports a universal AC input from 90~305VAC, ideal for unstable commercial grids and industrial 277VAC systems.
- Ultra-High Efficiency: State-of-the-art circuit design delivers industry-leading energy efficiency up to 96%, drastically reducing heat generation and operating costs.
- Active PFC: Built-in Active Power Factor Correction ensures high PF (>0.95) and complies with stringent EN61000-3-2 harmonic current limits.
- Industrial-Grade Protections: Features heavy-duty internal surge immunity (typically 4KV/6KV), alongside robust auto-recovery protections against short circuit, over-current, over-voltage, and over-temperature.
Power Range & Output Variants
The HLG series offers one of the most extensive wattage coverages in the industry, catering to everything from robust architectural accents to massive stadium lighting setups.
| Available Wattages | Standard Output Voltages | Ideal Applications |
|---|---|---|
| 40W, 60W, 80W, 100W, 120W, 150W, 185W, 240W, 320W, 480W, 600W | 12V, 15V, 20V, 24V, 30V, 36V, 42V, 48V, 54V | Stadium lighting, greenhouse and horticulture lighting, street lighting, high-bay factory lights, fishing lamps, and heavy-duty architectural illumination. |
Design Note: Unlike Constant Power (CP) drivers, the HLG series provides a fixed maximum voltage and current. When designing a system for direct-drive luminaires, ensure your total LED string voltage closely matches the driver's rated voltage to operate optimally in the Constant Current (CC) region.
Dimming & Control Suffixes
The HLG series utilizes a precise suffix naming convention to indicate its physical tuning and dimming capabilities. Select the suffix that best matches your integration needs:
| Suffix Code | IP Rating | Feature Description |
|---|---|---|
| Blank | IP67 | Standard fixed output version. Cables are provided for I/O connection. No manual adjustment or dimming. Ideal for harsh, wet locations requiring basic ON/OFF power. |
| A-Type | IP65 | Features internal potentiometers accessed via waterproof rubber plugs. Allows precise manual tuning of the Output Voltage (Vo) and Output Current (Io). |
| B-Type | IP67 | Built-in 3-in-1 Dimming function (1~10VDC, 10V PWM signal, or resistance). Controlled via an external dimming cable. |
| AB-Type | IP65 | The ultimate flexible option. Combines the manual Vo/Io tuning of the A-Type with the 3-in-1 remote dimming capabilities of the B-Type. |
| C-Type | IP20 | Terminal block type (available on select wattages) for indoor applications requiring hardwired screw terminal connections instead of pre-attached cables. |
