As power grids in Africa, the Americas, and other emerging markets enter periods of high-frequency fluctuations, stable power supply has become a critical factor for digital infrastructure. Routers, surveillance cameras, and IoT sensors can all experience operational interruptions or data risks when faced with power outages or unstable voltage.
In this context, the market demand for DC UPS (Direct Current Uninterruptible Power Supply) with fast switching capability and stable output continues to grow. To meet the needs of different power levels and voltage configurations, the GD series has launched three differentiated models, providing precise backup power solutions for various applications.
Since 2026, many regions have experienced repeated grid disruptions: from multiple blackouts in West Africa to large-scale outages in South America due to extreme weather, and regional power failures in North America triggered by winter storms. The unpredictability of power supply is increasing.
Notably, many core devices in modern network and security systems—such as routers, IP cameras, access control systems, and IoT gateways—rely on low-voltage DC power. These devices often lack built-in batteries, making them the most vulnerable points during outages.
This model features a single DC output port, supporting 9V / 12V manual switching to deliver stable DC power.
Key Features: Simple design, reliable output, easy deployment
Typical Applications:
Single routers
Standalone surveillance cameras
Access control devices
Small network terminals
Recommended for users with few devices, fixed voltage requirements, or those seeking basic backup power in home or small office environments.
With the same 18W total power, this version integrates three independent outputs (5V / 9V / 12V) for multi-voltage concurrent supply.
Key Features: Multi-voltage output, flexible compatibility, supports multiple devices
Typical Applications:
12V cameras + 5V sensors combinations
IoT gateways + smart terminal devices
Small smart home systems
Core advantage: eliminates the need for multiple adapters, enabling multi-device power management with a single unit.
This model increases total output power to 36W and enhances DC/POE port current capacity, suitable for higher-load environments.
Key Features: High power output, multi-device concurrency, enhanced load capacity
Typical Applications:
Multiple HD IP cameras
Small network switch clusters
Edge computing devices and gateways
Multi-terminal security and network systems
Targeted at professional security systems, small network rooms, and high-reliability deployment scenarios.
To ensure stable and safe operation of DC UPS in practical applications, the following guidelines are recommended:
Calculate the total power of all connected devices and allow 20%-30% extra margin to accommodate startup currents and peak loads.
Verify the voltage and current requirements of each device to ensure compatibility with UPS output ports. Mismatched voltage may prevent devices from starting or cause damage.
Select DC or POE port configurations based on device quantity and type to ensure future expandability.
As global grid stability declines, continuous operation of DC-powered devices is becoming a key metric in infrastructure planning. Compared with traditional UPS systems, DC UPS provides voltage directly aligned with end devices, offering higher efficiency and lower energy consumption in routers, security, and IoT applications. DC UPS products with multi-voltage output, high power density, and flexible port configurations are increasingly becoming standard equipment for small- and medium-sized networks and security systems.
