## Long description

DAHUA PFM3350-1000 is a Line-Interactive uninterruptible power supply (UPS) with 1 kVA input capacity and 600 W rated output power. Designed to provide basic power protection and short-term backup, this UPS includes two AC outlets, a sealed lead-acid 13.7 V 9 Ah battery and a 1.2 m power cable. Housed in a compact black plastic case, the unit delivers automatic voltage regulation and fast transfer to battery to maintain operation of CCTV systems, network equipment and small servers during mains disturbances.
Advantages
The unit features a wide input voltage range (170–280 VAC) and digital voltage stabilization to reduce sensitivity to grid fluctuations. With a rapid transfer time of 4–8 milliseconds, it ensures continuous power during brief outages, while built-in protections guard against overload, short circuit, overcharging and over-discharge. A fast charging cycle of approximately 4 hours restores the internal sealed lead-acid battery quickly, and quiet operation makes it suitable for office and monitoring environments.

CCTV camera systems and DVR/NVR units

How to use

The UPS will operate in automatic mode, regulating voltage when mains fluctuations occur and switching to battery power within 4–8 ms during an outage. Regularly check indicator LEDs or display (if present) to verify normal status and battery condition.
Usage recommendations
For reliable short-term backup, connect only essential equipment to the two available AC outlets and avoid overloading the UPS. Place the unit in a dry, ventilated area away from heat sources and direct sunlight. Perform periodic battery tests and replace the sealed lead-acid battery at the end of its service life to ensure continued protection for CCTV, networking gear and small servers.
