MEAN WELL ELG & ELGC Series Metal-Case LED Drivers
The ELG and ELGC series represent MEAN WELL's highly popular, heavy-duty LED drivers known for an optimal balance of high performance and cost-effectiveness. Housed in rugged metal cases, these series are incredibly versatile, engineered to power everything from indoor commercial fixtures to extreme outdoor street lighting.
- Dual-Mode vs. Constant Power: The ELG operates in a versatile Constant Voltage + Constant Current (CV+CC) mode, while the ELGC leverages a Constant Power (CP) design to deliver full wattage across diverse LED arrays.
- Rugged Metal Housing: Both series utilize a Class I metal enclosure with a functional ground, providing excellent thermal dissipation and structural integrity.
- High Environmental Resilience: Fully potted with thermal-conductive silicone, achieving an IP65 or IP67 rating (depending on the model suffix) to resist dust, moisture, and intense vibration.
- Energy Saving: Features ultra-low no-load/standby power consumption (typically < 0.5W), meeting strict global energy efficiency standards.
- Long Lifespan: Designed for extreme durability with a typical lifespan exceeding 50,000 hours, backed by a 5-year manufacturer warranty.
Technical Highlights
- Wide Input Range: Operates on a broad 100~305VAC input, making it compatible with standard commercial power grids and industrial 277VAC lines.
- Active PFC: Built-in Active Power Factor Correction ensures high operating efficiency (up to 93%) and significantly reduces harmonic distortion.
- Robust Surge Protection: Engineered to withstand high electrical surges (typically 6KV/4KV), ensuring high reliability in outdoor street, high-bay, and flood lighting applications.
- Comprehensive Protections: Fully equipped with auto-recovery safeguards against short circuit, over-voltage, and over-temperature.
Series Comparison: ELG vs. ELGC
While sharing the same robust housing and internal quality, the ELG and ELGC differ in their core power delivery architecture to suit varying project needs.
| Feature | ELG Series (Dual-Mode) | ELGC Series (Constant Power) |
|---|---|---|
| Output Mode | Constant Voltage (CV) + Constant Current (CC) | Constant Power (CP) |
| Wattage Range | 75W, 100W, 150W, 200W, 240W, 300W | 300W |
| Output Variants | 12V, 24V, 36V, 42V, 48V, 54V | L (Low Voltage/High Current) / M / H / AB Types |
| Ideal Application | LED strips, signage (12V/24V in CV mode), and direct-drive fixtures (36V-54V in CC mode). | Driving diverse high-power LED COBs or arrays where the voltage adjusts dynamically to maintain full wattage across different current settings. |
Design Note: The ELGC-300 is the ultimate choice for heavy-duty applications like stadium lighting or high-mast street lights, reducing inventory by powering various fixtures with a single driver. Conversely, the 12V/24V ELG models are the standard for powering long outdoor LED tape runs.
Dimming & Control Suffixes
Both series use a specific suffix naming convention to indicate their physical and dimming capabilities. Select the suffix that best matches your smart lighting project requirements:
| Suffix Code | IP Rating | Feature Description |
|---|---|---|
| Blank | IP67 | Standard fixed output version. No dimming or manual adjustment. Ideal for basic ON/OFF applications. |
| A-Type | IP65 | Features internal potentiometers accessible via waterproof rubber plugs. Allows manual adjustment of both the Output Voltage (Vo) and Output Current (Io). |
| B-Type | IP67 | Built-in 3-in-1 Dimming function (0~10VDC, 10V PWM signal, or resistance) via an external dimming control cable. |
| AB-Type | IP65 | Combines the manual Vo/Io adjustment of the A-Type with the 3-in-1 dimming capabilities of the B-Type for maximum flexibility. |
| DA-Type | IP67 | Integrated with DALI control technology for connection to addressable digital lighting networks in smart buildings. |
| D2-Type | IP67 | Built-in Smart Timer Dimming function, allowing programmable dimming profiles for energy-saving outdoor street lighting throughout the night. |
