5-in-1 Dimmable LED Drivers with Junction Box
FAHOLD L2-A 5-in-1 dimmable LED drivers with integrated junction box are designed for North American architectural, commercial and LED strip lighting projects. The series combines 100–277Vac input, 12V or 24V constant-voltage Class 2 output and an IP65 enclosed metal housing for protected electrical installations.
Available models cover 30W to 384W rated output, with single-output and multi-channel configurations. Depending on the selected dimmable version, supported control options include TRIAC, ELV, MLV, 0–10V, PWM and potentiometer control.
Compare L2-A models below by output voltage, rated wattage, current per channel and installation requirements. FAHOLD supports OEM lighting manufacturers and commercial project buyers with model selection, technical datasheets, dimmer compatibility review, samples and bulk quotations.

Enclosed 5-in-1 Dimmable LED Power Supplies for Commercial Lighting
FAHOLD L2-A enclosed LED power supplies combine constant-voltage output, multi-mode dimming and integrated junction-box construction for architectural and commercial lighting applications.
The 100–277Vac input platform supports projects using common North American supply voltages, including 120V and 277V. Available 12V and 24V models allow lighting manufacturers and contractors to match power supplies to different LED strip, linear fixture and architectural lighting requirements.
Unlike a driver selected only by nominal wattage, an enclosed Class 2 LED power supply must also be evaluated for output-circuit limits, controller compatibility, wiring requirements and the actual installation environment.
Compare 12V and 24V L2-A Class 2 LED Drivers
The correct output voltage depends on the connected LED load. FAHOLD offers L2-A configurations for both 12V and 24V constant-voltage lighting.
| L2-A Configuration | Available Rated Output Examples | Typical Application |
|---|---|---|
| 12V Single Output | 30W / 60W | Cabinet, shelf and display lighting |
| 12V Multi-Channel | 120W / 180W / 240W / 300W | Distributed 12V architectural lighting |
| 24V Single Output | 30W / 60W / 96W | Linear LED strips and commercial fixtures |
| 24V Multi-Channel | 192W / 288W / 384W | Multi-zone architectural and cove lighting |
For 24V commercial lighting, the following models are suitable starting points:
- L2-100X-024A — 96W, 24V, 4A: Single-output architectural lighting applications.
- L2-200X-024-2A — 192W, 24V, 2 × 4A: Two separate low-voltage lighting branches.
- L2-300X-024-3A — 288W, 24V, 3 × 4A: Three-channel distributed LED loads.
- L2-400X-024-4A — 384W, 24V, 4 × 4A: Four-channel commercial lighting systems.
Each Class 2 output channel must be evaluated against its individual electrical rating. The combined driver wattage should not be treated as the available capacity of a single channel.
Why Choose an LED Driver with Integrated Junction Box?
An integrated enclosure and junction-box design can simplify the planning of protected power connections in architectural lighting projects.
The L2-A IP65 metal enclosure is particularly relevant when an OEM fixture or commercial installation requires an enclosed power supply rather than an open-frame driver.
Before choosing a model, verify:
- AC input and low-voltage output connection requirements.
- Available mounting space and driver dimensions.
- Cable entry, conduit and connector requirements.
- Ambient temperature and ventilation conditions.
- Applicable safety listing and installation instructions.
The IP65 rating applies to the specified enclosure configuration. Suitability for a particular wet or damp location must be confirmed from the model documentation and complete installation arrangement.
100–277V Dimmable LED Drivers: Control Compatibility
The L2-A platform offers multi-mode dimming configurations for different architectural lighting control systems.
Depending on the selected version, available control options include TRIAC, ELV, MLV, 0–10V, PWM and potentiometer-based control.
For commercial applications using 0–10V, verify the controller interface, dimming range and required shutoff behavior.
For projects using phase-cut wall dimmers, confirm the actual dimmer model, allowed input conditions and low-end load behavior.
A 100–277Vac input rating does not automatically mean that every control method is suitable for operation at every input voltage.

Example: Selecting a 24V Class 2 LED Driver for Commercial Cove Lighting
Consider a commercial cove-lighting project with:
- 277Vac building supply.
- Two separate 24V LED strip loads.
- 80W maximum connected load per branch.
- Compatible 0–10V lighting control.
- An enclosed driver installation.
The L2-200X-024-2A provides two 24V / 4A outputs, each rated at 96W. It is a potential starting model because each 80W branch falls below its respective rated output.
Final approval should account for thermal operating conditions, applicable design margins, installation requirements and dimmer compatibility.
This example illustrates preliminary model selection rather than an approved wiring design.

Frequently Asked Questions
1. What is the difference between a standard LED driver and an L2-A driver with junction box?
The FAHOLD L2-A Series combines a constant-voltage LED driver with a protected metal enclosure and integrated junction-box architecture. This design is intended for projects requiring enclosed power connections, multi-mode dimming and Class 2 output configurations. Installation approval depends on the exact model and site requirements.
2. Are L2-A LED power supplies compatible with 277V commercial input?
L2-A models have a rated 100–277Vac input range, which includes common commercial supply voltages. However, the selected dimming interface and its compatibility with the actual 277V lighting control system must be checked separately.
3. Can one L2-A driver power several 24V LED strip runs?
Yes, provided the selected model has suitable output channels and the connected LED loads remain within the individual channel limits. For example, the L2-200X-024-2A offers two 24V / 4A outputs with a combined rating of 192W. Each channel must be evaluated independently.
4. Does the L2-A Series support TRIAC and 0–10V dimming?
The L2-A platform offers compatible multi-mode dimming configurations, including phase-cut and 0–10V control options. The available functions depend on the selected driver version. Customers should provide the controller or dimmer model before final approval.
5. Can I install an IP65 L2-A LED driver outdoors?
An IP65 enclosure provides a specified level of ingress protection, but that rating alone does not establish suitability for every outdoor or wet-location installation. Cable connections, installation orientation, temperature and applicable safety listing must also be considered. Projects requiring an IP67 power-supply platform can evaluate the FAHOLD L2-F Series.
6. Can FAHOLD provide OEM samples and bulk quotations for L2-A drivers?
Yes. FAHOLD supports sample evaluation, technical product matching and OEM/ODM project inquiries. Provide the intended product voltage, wattage, dimming method, installation conditions and estimated order quantity to request appropriate models and commercial terms.
