MEAN WELL HVG & HVGC Series High-Voltage Input LED Drivers
The HVG and HVGC series are heavy-duty, industrial-grade LED drivers specifically engineered to operate on high-voltage electrical grids (180~528VAC). These drivers are the premier choice for North American industrial facilities, greenhouses, and large-scale infrastructure projects utilizing 347V or 480V mains power.
- High-Voltage AC Input: Seamlessly handles two-phase or high-voltage commercial power (e.g., 347VAC, 480VAC) without the need for step-down transformers, significantly lowering installation costs.
- Rugged Metal Housing: Encased in a robust Class I aluminum chassis with a functional ground, providing exceptional thermal dissipation and structural strength.
- Environmental Resilience: Fully potted with thermal-conductive silicone, achieving an IP65 or IP67 rating to withstand severe weather, dust, and moisture in harsh indoor/outdoor environments.
- Reliable Lifespan: Built with premium components to ensure a lifespan exceeding 50,000 hours, backed by a comprehensive 5-year manufacturer warranty.
Technical Highlights
- Wide Operating Input: Accepts an ultra-wide input voltage of 180~528VAC (or 254~747VDC), making it immune to severe grid fluctuations.
- High Efficiency: Advanced circuit topology provides high energy conversion efficiency up to 91.5% (and higher on larger wattage models), minimizing heat output.
- Active PFC: Built-in Active Power Factor Correction ensures high PF (>0.90) at full load, complying with strict industrial power quality standards.
- Comprehensive Protections: Features robust auto-recovery protections against short circuit, over-current, over-voltage, and over-temperature.
Series Comparison: HVG vs. HVGC
The family is divided into two distinct output architectures to perfectly match your LED luminaire's electrical design.
| Feature | HVG Series (Dual-Mode) | HVGC Series (Constant Current) |
|---|---|---|
| Output Mode | Constant Voltage (CV) + Constant Current (CC) | Constant Current (CC) Only |
| Available Wattages | 65W, 100W, 150W, 240W, 320W, 480W | 65W, 100W, 150W, 240W, 320W, 480W, 650W, 1000W |
| Output Characteristics | Provides standard voltages (12V, 24V, 36V, 42V, 48V, 54V). | Provides high-voltage/low-current outputs to drive long strings of LEDs in series. |
| Ideal Applications | 24V/48V high-voltage industrial strip lighting, architectural accents, and general CV lighting. | High-bay factory lights, stadium floodlights, horticulture/grow lights, and street lighting operating on 347V/480V grids. |
Design Note: If you are designing a high-power horticulture or stadium light where the LEDs are wired in a long series (requiring voltages well over 100VDC), the HVGC series is the correct choice. For standard 24V or 48V systems on a 480V grid, use the HVG series.
Dimming & Control Suffixes
The HVG/HVGC series uses a suffix naming convention to indicate physical tuning and dimming interfaces. Choose the suffix that aligns with your industrial control system:
| 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 locations requiring basic ON/OFF power. |
| A-Type | IP65 | Features internal potentiometers accessed via waterproof rubber plugs. Allows manual tuning of the Output Current (Io) and Output Voltage (Vo). |
| B-Type | IP67 | Built-in 3-in-1 Dimming function (0~10VDC, 10V PWM signal, or resistance). Controlled via an external dimming cable. |
| AB-Type | IP65 | The most versatile option. Combines the manual current/voltage tuning of the A-Type with the 3-in-1 remote dimming capabilities of the B-Type. |
| D-Type / D2-Type | IP67 | Built-in Smart Timer Dimming. Allows the driver to follow a pre-programmed dimming schedule to save energy during off-peak hours (commonly used in street lighting). |
