## Long description

DAHUA PFM3350-600 is a Line-Interactive uninterruptible power supply (UPS) with 0.6 kVA (360 W) output capacity designed to protect small office or home equipment. The UPS is housed in a compact black plastic enclosure and provides two AC outlets, an internal 13.7 V 7 Ah lead-acid battery and a 1.2 m power cable. It is intended to maintain power to routers, DVR/NVR, network switches and CCTV devices during brief mains interruptions and to stabilize supply voltage in environments with fluctuating grid levels.
Advantages
The DAHUA PFM3350-600 offers line-interactive voltage regulation and digital voltage stabilization to reduce the impact of mains fluctuations without switching to battery for every small dip. Rapid transfer switching and built-in protections for overload, short circuit, overcharging and over-discharge provide reliable operation for connected equipment. Compact size and quiet operation make it suitable for installation near sensitive devices in offices or small installations.
Suitable for
Home and small office routers and modems
DVR / NVR and CCTV recording devices
Network switches and small network equipment
Other low-power electronic devices requiring short-term backup

Connect the UPS to mains power using the supplied 1.2 m power cable and allow the internal battery to charge for the recommended initial charging period. Plug required devices into the two AC outlets and switch the UPS on. The unit will regulate voltage automatically in normal operation and switch to battery power during mains interruptions. Observe the device indicators or any status LEDs for battery and fault information.
Usage recommendations
To maximize battery life and performance, avoid deep discharges, keep the UPS in a moderate ambient temperature, and perform periodic battery checks. Use the DAHUA PFM3350-600 for short-term backup and voltage stabilization for low-power network and CCTV equipment rather than extended runtime for high-power devices.
