Fonte de alimentação ininterrupta DAHUA DH-PFM350-360 Line-Interactive 0,6 kVA / 360 W, 12 V 7 Ah, compacta preta

The DAHUA DH-PFM350-360 is a compact Line-Interactive uninterruptible power supply providing 0.6 kVA (360 W) output power and equipped with a 12 V, 7 Ah battery. Designed for use where short-term backup and voltage stabilization are required, this UPS protects connected equipment during mains disturbances, brief outages and voltage sags or surges while keeping a small footprint (279×101×142 mm) and a weight of 4.25 kg.

Advantages

This UPS supports a wide input voltage range and includes boost and buck AVR to stabilise output voltage without discharging the battery during common fluctuations. The unit provides off-mode charging, a cold-start function for starting on battery when mains are absent, and comprehensive protection features to guard connected devices against power anomalies. Its sine waveform output and line-interactive design ensure compatibility with CCTV systems, routers and small office equipment.

Suitable for (tasks / use cases)

• CCTV cameras and network video recorders requiring uninterrupted power for short outages
• Home and small office routers, modems and network switches
• Point-of-sale terminals and small payment systems needing brief backup to complete transactions
• Desktop peripherals and small office devices where compact backup is preferred

How to use

Place the UPS on a stable, flat surface in a ventilated area and connect the internal battery according to the manufacturer instructions before first use. Plug critical equipment into the UPS output sockets and connect the UPS input to mains power. The unit will regulate voltage using AVR during normal operation and switch to battery mode automatically when mains fail. Use the cold-start function to power connected equipment from the battery if mains power is absent. Observe the load limits to avoid overload and allow the battery to charge fully after extended discharge.

Recommendations

For reliable operation, regularly test the UPS under load and replace the battery after its rated life or if runtime decreases significantly. Keep ventilation unobstructed, avoid placing the unit near heat sources or in high humidity, and ensure connected devices do not exceed the 360 W output rating. Use this UPS for short-term backup and voltage stabilization rather than long-duration power supply.
