300W 12V LED Power Supply Overview
The Orix Pro Slim 300W 12V LED Power Supply provides stable constant-voltage power for professional 12V LED lighting systems. It delivers 12V DC at up to 25A, giving a maximum rated output of 300W.
Its compact ventilated metal housing makes it suitable for architectural projects where installers need high output capacity in a relatively small space. Moreover, the integrated brightness preset switches allow output selection at 100%, 75%, 50%, or 25%, while the Slow Start function provides a smoother switch-on effect.
Therefore, this power supply works particularly well with LED strips, linear lighting, cabinet lighting, signage, retail displays, joinery, and other compatible 12V constant-voltage systems.

Adjustable Brightness Presets
A distinctive feature of this power supply is the integrated BRIGHTNESS selector.
The available preset levels shown on the housing are:
100% – 75% – 50% – 25%
These settings allow installers to configure the output level according to the required application. As a result, one driver can offer greater flexibility during commissioning than a basic fixed-output power supply.
However, these switches should not be treated as a replacement for a conventional wall dimmer, DALI system, or 0–10V controller unless the manufacturer specifically confirms that functionality.
Slow Start Function
The unit also includes a selectable SLOW START control.
When enabled, this function allows the lighting system to switch on more gradually instead of reaching full output immediately. Consequently, it can create a smoother visual transition in decorative and architectural lighting installations.
This feature can work especially well in:
- Residential ambient lighting
- Hotel rooms
- Restaurants
- Lounge areas
- Decorative coves
- Retail displays
- Feature lighting
High-Capacity 12V Constant Voltage Output
The driver supplies up to 25A at 12V DC. Therefore, it can support substantially larger loads than smaller 60W, 100W, or 150W power supplies.
Typical compatible applications include:
- 12V LED strips
- Linear LED profiles
- Cove lighting
- Cabinet lighting
- Joinery lighting
- Display lighting
- Signage
- Furniture lighting
- Decorative architectural lighting
Installers should always confirm that the connected lighting system requires 12V DC constant voltage before connection.
LED Strip Load Calculation
Correct load calculation helps designers select the right driver.
For example, if a 12V LED strip consumes 12W per meter and the project uses 20 meters:
12W × 20m = 240W
A 240W load remains below the nominal 300W capacity.
However, designers should still keep an appropriate operating margin rather than loading the driver continuously at its absolute maximum. In addition, ambient temperature, cable length, and installation conditions can affect system performance.
Suitable for Architectural Linear Lighting
The 300W 12V LED Power Supply works particularly well with high-load architectural LED systems.
Designers can use it with compatible LED strips installed inside:
- Recessed aluminum profiles
- Surface-mounted channels
- Cove profiles
- Ceiling profiles
- Wall profiles
- Cabinet channels
- Retail display systems
Moreover, its slim enclosure makes it easier to conceal the driver within architectural details while keeping it accessible for service.
Residential Applications
In villas and apartments, the driver can support larger decorative lighting circuits.
Possible applications include:
- Living-room cove lighting
- Kitchen LED profiles
- Bedroom ambient lighting
- Wardrobes
- TV walls
- Decorative shelving
- Ceiling details
- Joinery lighting
Furthermore, the brightness presets can help installers fine-tune the lighting output during commissioning.
Hospitality Lighting
Hotels, restaurants, cafés, and lounges often use extensive low-voltage LED lighting.
The Orix Pro Slim power supply can support compatible 12V systems for:
- Hotel headboards
- Restaurant coves
- Bar shelving
- Reception counters
- Decorative wall details
- Joinery
- Display lighting
- Ceiling features
Additionally, the Slow Start function can provide a smoother lighting effect in atmosphere-focused spaces.
Retail and Commercial Applications
Retail interiors frequently require LED lighting across several displays or long shelving systems.
Therefore, this power supply can support:
- Product shelves
- Display cabinets
- Retail counters
- Illuminated furniture
- Signage
- Feature walls
- Showroom lighting
- Decorative linear installations
Its high output capacity can also reduce the number of smaller drivers required in some projects.
Voltage Drop in 12V Systems
Voltage drop requires particular attention with 12V systems because they carry relatively high current.
For example, this driver can supply up to 25A. Therefore, long cable runs require suitable conductor sizes.
Designers should consider:
- Cable length
- Cable cross-section
- Total current
- Driver position
- LED strip length
- Number of feed points
For longer installations, contractors may divide the load into several branches or provide multiple power-injection points.
Ventilated Metal Housing
The large side ventilation openings help heat escape from the internal components.
However, installers should still provide adequate airflow around the power supply. Moreover, they should avoid installing it inside completely sealed spaces unless the manufacturer approves that installation method.
Keeping the driver accessible also simplifies inspection and future maintenance.
Professional Electrical Connections
The power supply provides clearly identified terminals for:
AC Input
- L – Line
- N – Neutral
- Earth
DC Output
- V+
- V-
Before energizing the unit, electricians should check polarity, cable size, connected load, and electrical protection.
Because the 12V output can carry high current, correct cable sizing remains especially important.
