The Sostron Ares Series is a fixed installation outdoor LED solution engineered to reduce Operating Expenses (OpEx). By replacing traditional steel cabinets with a die-cast aluminum chassis, the Ares series maximizes heat dissipation without requiring power-hungry air conditioning. Designed for 24/7 operation in harsh climates, it combines high brightness (10,000 nits) with intelligent power management.
Heat is the primary cause of LED attenuation and failure. The Ares Series utilizes an all-aluminum profile with a high thermal conductivity rate (approx. 205 W/m·K), which is 3x more efficient than traditional iron cabinets.
Passive Cooling: The cabinet design acts as a giant heat sink, eliminating the need for internal fans.
No AC Required: This design allows the screen to operate in temperatures up to 60°C without external HVAC systems, significantly lowering your monthly electricity bill.
Visibility in direct sunlight is non-negotiable.
Brightness: Configurable up to 10,000 nits, ensuring clear visibility even under direct equatorial sunlight.
Light Sensors: Integrated ambient light sensors communicate with the control card to automatically adjust brightness curves, preventing light pollution at night while saving energy.
Contrast Ratio: Using high-quality SMD (Surface Mounted Device) or DIP technology with black masks to achieve a 6000:1 contrast ratio for deep blacks.
Built to withstand extreme weather conditions, from desert sandstorms to coastal humidity.
Waterproof Design: Fully sealed modules with IP66 front / IP54 rear ratings.
Corrosion Resistance: The aluminum alloy chassis is naturally rust-resistant, making it ideal for seaside installations where salt spray corrodes standard steel screens.
Hardware is only half the story. The Ares Series comes native with Sostron’s Smart Monitoring Protocol:
Real-Time Diagnostics: Monitors the voltage, temperature, and status of every receiving card.
Predictive Maintenance: The system alerts your central CMS dashboard if a module shows abnormal heat patterns before it fails.
Remote Power Control: Reboot or cut power to specific sections of the screen remotely via the cloud, reducing truck rolls.
Calculate your DOOH billboard's 30%-40% energy saving potential.

The Ares Series is the industry standard for high-impact outdoor digital billboards. Engineered to withstand extreme UV exposure, heavy rain, and fluctuating temperatures, the Ares series requires professional-grade structural and electrical integration to ensure its 10-year design life.
Outdoor billboards act as massive sails. The Ares series, with its robust aluminum/steel cabinet, requires a foundation that accounts for dynamic wind pressure.
Wind Velocity Compliance: We provide structural calculations supporting wind speeds up to 45m/s (Hurricane Force). For coastal regions, we recommend our reinforced mounting points and high-tensile bolt kits.
Seismic Load Factor: Our engineering team can provide vibration-damping mount designs for earthquake-prone zones, ensuring the LED modules remain securely seated during seismic events.
Expansion Joint Design: For screens exceeding 10 meters in width, we recommend a 5mm structural gap every 5 cabinets to accommodate the thermal expansion of the steel sub-frame without putting stress on the LED modules.
An IP65/IP66 rating is only effective if the installation is sealed correctly.
Rear Cabinet Sealing: For fixed installations without a rear enclosure, ensure all power and data entry points use our IP-rated aviation connectors and cable glands.
Secondary Drainage Path: Even with an IP65 rating, we recommend designing the steel structure with a 1% downward slope and drainage weep holes at the bottom of the structure to prevent water from pooling during tropical storms.
Corrosion Protection: For projects within 5km of the ocean, the Ares series can be upgraded with a C5-M grade anti-corrosion coating on the internal frame.
The Ares series can reach up to 8,000 – 10,000 nits. Managing the heat generated by these high-performance LEDs is critical:
The 10cm Rule: Always maintain at least 100mm (4 inches) of clearance between the back of the LED cabinet and the mounting surface to allow for natural convection (Chimney Effect).
Active Cooling Requirements: If the screen is installed in a recessed wall or a “boxed-in” design, a forced-air cooling system (Axial Fans) must be integrated, providing at least 0.5 m³/min of airflow per square meter of display area.
Outdoor screens are magnets for induced lightning and electrical surges.
Grounding Resistance: The entire steel structure must be grounded with a resistance of ≤4Ω. This protects the driver ICs from electrostatic discharge (ESD).
Transient Voltage Surge Suppressor (TVSS): We recommend installing a Type 2 SPD at the main distribution board to mitigate surges caused by grid instability or nearby lightning strikes.
Sequential Power-On: To prevent high in-rush currents from tripping breakers, use a Power Sequencer to turn on the screen in stages (Module by Module).
The Ares series supports multiple professional mounting configurations:
Unipole/Bi-pole: Standard roadside billboard setup.
Wall-Mount (Front or Rear Access): Features a dual-maintenance design.
Cantilever (F-Frame): For over-the-road traffic signage.
Roof-Top Mount: Includes custom bracing designs to distribute load across building columns.
The Ares Series outdoor LED displays are designed for high-performance, durability, and versatility. With ultra-high brightness, modular design, lightweight aluminum cabinets, and front/rear maintenance access, they are ideal for outdoor advertising, sports venues, commercial plazas, and urban landmarks. Choosing Ares ensures reliability, energy efficiency, and long-term cost savings.
The Ares outdoor LED displays offer several key advantages:
High brightness: Up to 10,000 nits for clear visibility in all lighting conditions.
Lightweight design: Each cabinet weighs just 20 kg, reducing structural burden.
Energy efficiency: Fanless design and optimized power consumption.
Easy maintenance: Front and rear access for fast servicing and minimal downtime.
Versatile aesthetics: Multiple color options (silver, black, white) to match different environments.
Yes. Due to the lightweight aluminum frame (28kg/sqm), the wind load on the mounting structure is significantly reduced compared to steel cabinets. We can provide structural calculation reports for your engineering team.
By eliminating the need for air conditioning and utilizing high-efficiency power supplies (PFC), the Ares Series typically reduces power consumption by 30-40%, delivering a faster ROI.
Yes, the Ares Series is fully compatible with Novastar (A8s/A10s), Colorlight, and integrates seamlessly with Sostron’s proprietary Cloud CMS.
We’ve delivered thousands of screens for our clients and partners in retail stores,public transportation,hotels,restaurants and more.SoStron become one of the trusted brand in the industry.
