What equipment can the Dahua DH-PFM3350-1500 protect?

The DH-PFM3350-1500 is designed for compatible computer, networking and security equipment whose combined load remains within both the 1500VA and 900W ratings. Typical applications may include an NVR or DVR, PoE switch, modem, router, monitor and selected CCTV accessories. Add the real wattage of every connected device and keep practical headroom rather than operating continuously at the maximum rating.

How long will the UPS run during a power outage?

Dahua’s current specification does not publish one fixed runtime for this model. Backup time changes with the connected wattage, battery condition, battery age, ambient temperature and charging state. A lightly loaded recorder and router will generally operate longer than a system close to 900W. Runtime should be tested with the intended equipment after the batteries have completed their initial charge.

Does the PFM3350-1500 provide pure sine-wave output?

In normal AC mode, Dahua specifies a pure sine-wave output. In battery mode, the DH-PFM3350-1500 supplies a simulated sine wave. This suits many standard electronic loads, but equipment that specifically requires pure sine-wave power while operating from battery should be matched to an appropriate online or pure-sine-wave UPS instead. Check the connected equipment manufacturer’s power requirements before purchase.

How quickly does the UPS switch to battery power?

The specified transfer time is typically 4 to 8 milliseconds. This brief switching interval is characteristic of a line-interactive UPS and is intended to keep compatible connected equipment operating through common mains interruptions. It is not a zero-transfer-time system, so highly sensitive equipment that cannot tolerate any interruption may require an online double-conversion UPS.

What batteries are built into this Dahua UPS?

The DH-PFM3350-1500 contains two 12V 7Ah sealed lead-acid batteries. Dahua specifies a 1A charging current and approximately 4 to 6 hours to reach 90% charge, while the user manual recommends charging for at least 6 hours before initial use. Battery performance reduces with age and heat, and replacement should use the same quantity and type under suitable technical supervision.

Does this UPS use Australian power sockets?

The official Dahua specification lists a European-standard input plug and four European-standard output sockets. Buyers must confirm the supplied regional version and electrical compatibility before ordering or connecting equipment. Do not assume that the unit has Australian AS/NZS 3112 outlets merely because its nominal output is 230VAC. Use only an approved connection arrangement suitable for the local electrical requirements.

What alarms and protection features are provided?

The UPS uses coloured status indicators and audible warnings for mains operation, battery mode, low battery, overload, battery replacement and fault conditions. Dahua lists protection against overload, short circuit, battery overcharge and battery over-discharge. Overload behaviour varies according to the operating mode and severity, so an alarm should be investigated promptly rather than silenced by adding more load.

What should I check before ordering the PFM3350-1500?

Confirm the combined VA and wattage of the intended equipment, the required backup duration, the European plug and socket arrangement, and whether simulated sine-wave battery output is acceptable. The UPS is intended for protected indoor use from 0 °C to 40 °C with adequate ventilation. Security Wholesalers can assist with basic capacity matching, but final electrical suitability must be confirmed for the installation.

Description

Product SKU: DH-PFM3350-1500

Product Overview

The Dahua DH-PFM3350-1500 is a 1500VA/900W line-interactive UPS designed to provide short-term battery backup and voltage stabilisation for compatible CCTV, networking and computer equipment. Its wide 170–280VAC input range helps manage common mains fluctuations, while a typical 4–8ms transfer time switches supported loads to battery power during an outage. Two built-in 12V 7Ah sealed lead-acid batteries recharge to approximately 90% in 4–6 hours and supply a simulated sine-wave output when mains electricity is unavailable. Status lights and audible alarms identify mains operation, battery mode, low battery, overload, battery replacement and fault conditions. The unit is fanless and includes four European-standard output sockets, so plug compatibility and total equipment load must be confirmed before use.

Key Capabilities

1500VA / 900W Backup Capacity

Supports compatible security, network and computer equipment whose combined demand remains within both the apparent-power and real-power limits.

Line-Interactive Voltage Regulation

The 170–280VAC input range and digital voltage stabilisation help the UPS manage common mains fluctuations before battery operation is required.

Fast 4–8ms Transfer

A typical transfer time of 4 to 8 milliseconds allows compatible connected equipment to continue operating when mains power fails or moves outside the supported range.

Dual Built-In 7Ah Batteries

Two sealed 12V 7Ah lead-acid batteries provide short-term backup power and recharge to approximately 90% in 4 to 6 hours under the stated conditions.

Four Output Sockets

Four European-standard output sockets allow several compatible devices to be protected, subject to the shared 1500VA/900W load limit.

Fanless Indoor Design

The UPS has no built-in fan, supporting quieter operation in offices, reception areas and protected equipment spaces with suitable ventilation.

Best For

Medium CCTV Systems: Helps protect a compatible recorder, PoE switch and selected network equipment during brief outages.
Routers and Modems: Supports compatible network equipment to help maintain security-system connectivity through short interruptions.
Security Workstations: Can protect a carefully sized combination of recorder, monitor and network equipment without a noisy cooling fan.
Sites with Mains Fluctuation: The 170–280VAC input range and digital voltage stabilisation help manage varying supply conditions.
Short-Term Backup Requirements: Suits systems needing enough time to ride through brief outages or complete an orderly shutdown.

Why Choose the DH-PFM3350-1500

The DH-PFM3350-1500 provides more load capacity than compact desktop UPS models while retaining the straightforward operation of a line-interactive design. Its 1500VA/900W rating can support a carefully planned mix of security and networking equipment, while the 170–280VAC input window helps reduce unnecessary battery use during common voltage fluctuations. Dual 7Ah batteries, four output sockets, a 4–8ms transfer time and clear audible warnings provide practical protection without the complexity of a large online UPS. Fanless operation is valuable in quieter indoor areas. Supplied by Security Wholesalers, this model is best chosen after checking wattage, VA demand, required runtime, waveform and socket compatibility.

Buyer Decision Tips

Load-Sizing Tip: Add the real wattage of every connected device and check the VA demand as well. Keep the design below both 900W and 1500VA, with practical headroom for start-up demand and battery ageing.

Outlet and Runtime Tip: Dahua lists European input and output connections. Confirm the regional version and an approved local connection method, then test runtime with the intended load after the initial battery charge.

PoE Switch and Camera Networks

Can support a carefully calculated PoE switch and connected cameras when the combined real power, start-up demand and desired runtime fit within the UPS limits.

Router and Modem Protection

Helps keep compatible network equipment operating through short interruptions so remote access and connected security services have a better chance of remaining available.

Security Workstations

May protect a correctly sized recorder, monitor and selected network equipment where the total load remains below both 1500VA and 900W.

Access Control and Intercom Equipment

Can support compatible control and communication devices after their combined wattage, waveform requirements and plug arrangement are verified.

Voltage-Fluctuation Environments

The 170–280VAC input range and digital voltage stabilisation help manage common mains variations without immediately relying on the battery.

Choosing the Right Model

Choose the DH-PFM3350-1500 if: The total connected load is comfortably below 1500VA/900W and short-term backup is required.
Choose a smaller UPS if: The connected equipment draws substantially less power and fewer output sockets are needed.
Choose a higher-capacity UPS if: The recorder, PoE switch, cameras, monitor and network equipment approach the stated limits or require longer runtime.
Choose a pure-sine-wave UPS if: Connected equipment specifically requires pure sine-wave power while operating from battery.
