Dahua DH-PFM3350-600 650VA Offline UPS for Reliable Backup Power in Bangladesh

The Dahua DH-PFM3350-600 is a 650VA offline UPS designed to keep essential home and office electronics running during power cuts and unstable electricity. With a rated output of 360W, this UPS is well-suited for protecting devices that need stable power to avoid sudden shutdowns, corrupted work, or interruptions to connectivity. If you rely on a desktop PC, router, CCTV system, or other networking equipment, this model helps maintain continuity when the grid becomes unreliable.

As an offline UPS, it provides backup power by switching to battery support when input power drops or fluctuates beyond safe limits. This makes it a practical choice for everyday environments where you want dependable protection without the complexity of higher-end power systems. Compared to basic surge-only protection, an offline UPS adds real runtime during outages—helping you save work, keep monitoring systems active, and maintain network stability long enough to respond.

Key Power Specs: 650VA Capacity, 360W Output, and Stable 230V

This UPS supports a 650VA capacity with 360W output power, making it appropriate for moderate power loads. The output voltage is 230VAC by default, which aligns with common power requirements for many office and home electronics. For frequency compatibility, it supports output frequency of 50/60Hz, allowing flexible use across different power standards and setups.

For input stability, the Dahua DH-PFM3350-600 accepts an input voltage range of 170V to 280VAC. This wide operating window helps reduce unnecessary battery switching when voltage fluctuates, which can improve overall battery usage and provide smoother protection for connected equipment. The input current is specified as 2.9A, while the output current reaches up to 2.7A for reliable device support within the UPS rating.

Backup Runtime: Up to 20–40 Minutes

The UPS offers backup time of up to 20–40 minutes, depending on the connected load. This runtime range is especially useful for typical scenarios such as finishing critical tasks on a PC, keeping a router online for continued internet access, or ensuring CCTV recording continues long enough to manage the situation. For best results, match the UPS load to your equipment needs and avoid exceeding the 360W output capacity.

Designed to operate in varied environments, the Dahua DH-PFM3350-600 works at operating temperatures from 0°C to 40°C and supports humidity up to 90% (non-condensing). It also supports storage temperatures from -15°C to 55°C, making it easier to store safely when not in use. These environmental specifications make it a practical UPS option for Bangladesh homes and offices where temperature and humidity can change throughout the year.
