Uninterruptible Power Supply DAHUA PFM3350-600 600VA

DAHUA PFM3350-600 is a 600VA uninterruptible power supply (UPS) designed to provide short-term backup power and basic surge and voltage protection for small CCTV installations, network equipment and desktop devices. The compact design allows easy placement near recording devices, routers or workstations and supplies temporary power during mains interruptions to enable safe shutdown or continued short-term operation.

Advantages

This UPS delivers a stable 600VA output suitable for low-power surveillance and networking equipment, reducing the risk of data loss and service interruptions. It provides protection against short-term power outages and common voltage fluctuations, and its compact footprint makes it easy to integrate into existing setups without occupying significant space. The unit is appropriate for environments where brief backup and orderly shutdown capability are required.

Suitable for

• Small CCTV systems and DVR/NVR front-end devices
• Home and small-office routers, switches and modems
• Desktop PCs, monitors and peripheral devices requiring short-term backup
• Edge devices and small network appliances that need uninterrupted operation during brief outages

Key specifications

• Rated capacity: 600VA suitable for low-power setups
• Output type: single-phase AC output for common consumer and small-business equipment
• Form factor: compact chassis designed for desktop or rack-adjacent placement
• Protection features: backup power during outages and mitigation of voltage fluctuations and surges
• Typical applications: CCTV cameras and recorders, network devices, desktop equipment

How to use

Install the UPS on a stable, level surface close to the equipment to be protected. Connect the UPS to the mains supply and allow the internal battery to charge before relying on it for backup. Plug critical devices into the UPS output sockets, ensuring the combined load does not exceed the rated capacity. In the event of mains failure, the UPS will supply temporary power automatically; use this time to perform an orderly shutdown of sensitive equipment or to maintain essential services for short periods.

Usage recommendations

For reliable operation, periodically verify battery charge status and perform battery maintenance as specified by the manufacturer. Avoid connecting high-power appliances that exceed the UPS capacity, and place the unit in a ventilated space away from direct heat sources and moisture.
