Description

DAHUA 1200VA UPS (DH-PFM350-720-A) – Smart Power Protection for CCTV, Networking, and Office Devices

In an increasingly digital world where devices are constantly connected and operational, an uninterruptible power supply (UPS) has become a vital tool. The DAHUA 1200VA UPS (DH-PFM350-720-A) stands out as a compact, line-interactive UPS solution ideal for CCTV systems, home and small office networking devices, point-of-sale (POS) terminals, and low-power desktop setups. Manufactured by Dahua Technology, a global leader in security and surveillance solutions, this UPS is engineered with intelligence, stability, and performance in mind.

The DAHUA 1200VA UPS offers 720W of output power, 4 universal AC output ports, and dual batteries for dependable backup during power outages. Designed to seamlessly integrate with both surveillance and IT infrastructure, this UPS is a strong ally in environments where even a few seconds of downtime could result in lost data, missed surveillance footage, or disrupted workflows.

⚙️ Product Overview

The DAHUA 1200VA UPS is a line-interactive type UPS, meaning it not only provides battery backup power but also incorporates Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery mode. This conserves battery life and improves efficiency, making the UPS suitable for regions where electricity supply may be unstable or inconsistent.

With a switch-over time of less than 10 milliseconds, the DAHUA 1200VA UPS reacts quickly during a power outage, ensuring your systems remain online without skipping a beat. This is especially crucial in surveillance setups where even brief interruptions can cause data loss or gaps in recorded footage.

Its cold-start capability enables users to power on devices even when utility power is unavailable—useful in blackout scenarios where immediate connectivity or surveillance access is necessary. Meanwhile, LED indicators and audible alarms keep users informed of UPS status, including low battery, overload, or fault conditions.

🔍 Detailed Product Insight

⚡ High-Capacity Performance

The 720W output power makes this DAHUA 1200VA UPS suitable for supporting multiple critical devices during a power outage. Whether it’s a set of CCTV cameras and DVRs, a router/modem combination, or a POS system, this UPS provides reliable uptime to ensure operational continuity.

For example:

• Routers and modems (~50W): Up to 60 minutes runtime

• DVR/NVR systems (~100W–150W): 20 to 30 minutes runtime

• POS terminal + thermal printer (~120W): 25 minutes runtime

• Entry-level desktop PC + monitor (~250W): 10 to 15 minutes runtime

These estimates make the unit ideal for short power interruptions or controlled shutdowns in longer outages.

🔌 Designed for CCTV and Networking

Security systems are a key use case for this DAHUA 1200VA UPS model. Sudden power loss can lead to:

• Missed surveillance footage

• Damaged video files

• Unresponsive IP cameras or DVRs

• Delayed motion alert delivery due to offline routers

This is why the DAHUA 1200VA UPS was engineered with four output ports, enabling simultaneous support for a DVR/NVR, router, switch, and another device (like a camera controller or monitor). The pure sine wave pass-through in mains mode helps avoid issues with sensitive power supplies in surveillance gear.

🔋 Dual Battery Backup

Equipped with two 12V 7Ah batteries, this DAHUA 1200VA UPS stores more energy compared to single-battery systems. This means extended runtime and greater stability during power outages. The system is also designed for efficient recharging, reaching 90% battery capacity in about 6 hours, so it’s ready to protect again after each use.

The sealed lead-acid batteries are replaceable, allowing you to extend the overall lifespan of the UPS for years with minimal maintenance.

🛡️ Protection Features

The DAHUA 1200VA UPS includes multiple layers of protection to ensure connected devices are safe:

• Surge Protection: Safeguards devices from power spikes

• Overload Protection: Prevents overdraw by cutting off power during excessive loads

• Short Circuit Protection: Quickly shuts off output to prevent damage to UPS or connected devices

• Deep Discharge Protection: Protects the battery from being drained beyond safe levels

These protections not only enhance device safety but also improve battery longevity and reduce maintenance.

📶 Intuitive Status Monitoring

The built-in LED indicators and audible alarms provide real-time information about the DAHUA 1200VA UPS operating state:

• Green: Normal operation

• Yellow: Battery charging

• Red: Battery in use

• Flashing LEDs & Beep Codes: Help diagnose specific issues quickly (e.g., overload, low battery)

This easy-to-understand feedback system is great for non-technical users who need to respond quickly during outages.

🎯 Use Case Scenarios
