Dahua 800VA 2-Port Line-Interactive Uninterruptible Power Supply (DH-PFM350-480A)

The Dahua 800VA 2-Port Line-Interactive Uninterruptible Power Supply (DH-PFM350-480A) is a professional-grade, line-interactive power security solution specifically engineered to safeguard surveillance networks, small business communication nodes, and home office workstations. Providing a dependable 480W / 800VA workload capacity, this unit is highly optimized to handle the distinct electrical profiles and startup wattages of surveillance systems, ensuring that security digital recorders (NVRs/XVRs) and local network switches stay up and running during sudden blackouts or voltage drops.

Built to perform reliably under unpredictable grid environments, the DH-PFM350-480A handles erratic input voltages ranging from 150V to 275V AC. It utilizes a microprocessor-controlled Automatic Voltage Regulation (AVR) module to actively stabilize power output to a clean 220V standard without prematurely drawing on its battery reserves. This model includes two universal/European output ports right on its chassis, delivering full battery backup alongside robust surge protection. This design provides a safe, spark-free workspace for your equipment without the need for loose, third-party plastic adapters.

Dahua 800VA 2-Port Line-Interactive Uninterruptible Power Supply (DH-PFM350-480A) Key Features & Product Highlights

• Tailored Surveillance Support: Engineered specifically to meet the continuous operational needs and startup demands of multi-channel network video recorders (NVRs) and PoE security cameras.

• High-Capacity 9Ah Internal Battery: Features a robust 12V/9Ah sealed lead-acid battery, which offers a larger power reservoir and longer runtime padding than cheaper 7Ah models in the same segment.

• Advanced Automatic Voltage Regulation (AVR): Constantly tracks and corrects extreme under-voltage brownouts and over-voltage grid surges, preventing system component strain.

• High-Speed Transfer Efficiency: Boasts an automated switchover response time of less than 10 milliseconds, which keeps sensitive security recording feeds active without reboots.

• Cold-Start Energy Initialization: Enables you to turn on the UPS chassis to deliver immediate emergency power to connected devices like Wi-Fi routers or fiber modems during a prolonged blackout.

• Multi-Stage LED & Audible Safety Feedback: Employs distinct red, green, and yellow flashing status lights combined with clear mechanical acoustic alarms to alert users to overload conditions, low battery levels, or fault statuses.

Dahua 800VA 2-Port Line-Interactive Uninterruptible Power Supply (DH-PFM350-480A) Pros & Cons

Pros

• Excellent Surveillance Optimization: Perfectly matched for security setups, providing stable backup and reducing video frame loss caused by power fluctuations.

• Durable Hybrid Structural Build: The rugged steel-and-plastic hybrid body handles heat dissipation much better than all-plastic alternatives.

• Dense 9Ah Battery Core: Delivers longer runtime reserves (typically 10–25 minutes depending on load) than standard 7Ah entry-level units.

• Off-Mode Smart Charging: The device continues to recharge its internal battery array safely even when turned completely off, keeping it ready for sudden cuts.

Cons

• Limited Port Density: Features only 2 output outlets, which means you’ll need a high-quality power strip if you plan to connect multiple small peripherals.

• Modified Inverter Waveform: Uses a modified sine wave when running on battery power; while perfect for surveillance systems and standard IT equipment, it is not recommended for high-end audio gear.

Dahua 800VA 2-Port Line-Interactive Uninterruptible Power Supply (DH-PFM350-480A) Suitable Application Areas

• CCTV & Surveillance Stations: Keeps 8-channel or 16-channel NVRs, local PoE camera injectors, and central monitor matrices online to maintain continuous security coverage.

• Smart Home & Small Office Desktops: Provides solid power protection for a mid-range business computer tower, an external display, and local network drives.

• Retail POS & Cashier Enclosures: Powers digital barcode scanners, receipt printers, and point-of-sale checkout screens simultaneously at busy retail hubs.
