How long will this 1.5kVA UPS power a standard 300W load during a blackout?
Based on the 900W capacity and dual 7Ah batteries, you can expect approximately 10–15 minutes of runtime for a 300W load; for an exact runtime calculation for your specific hardware, please contact our support at apsardze24@gmail.com.
What happens if I accidentally overload the 900W capacity?
The UPS is equipped with intelligent power protection features. If the load exceeds 900W, the unit will trigger an audible overload alarm and shut down automatically to protect its internal circuitry from damage.
Does the 4ms response time prevent servers or NAS drives from rebooting?
Yes, the rapid 4ms to 8ms switching time ensures that most power-sensitive devices, such as servers, NAS units, and desktop computers, continue to run without interruption or rebooting during a power failure.
How loud is the cooling fan on the Dahua PFM3350-1500 during normal use?
The unit features a built-in cooling fan that activates during battery mode or when the internal temperature rises. While it is designed for quiet operation, it may be audible in a completely silent office or bedroom setting during high-load charging.
How many devices can I plug into the back of this UPS?
The Dahua PFM3350-1500 is equipped with 4 AC outlets. Ensure the total power consumption of all connected devices does not exceed the maximum output capacity of 900W.
Can the internal batteries in this 1.5kVA UPS be replaced eventually?
Yes, the Dahua PFM3350-1500 uses two standard 12V 7Ah Lead-Acid batteries. These can be replaced by a qualified technician when they reach the end of their typical 3-to-5-year lifespan.
What is the warranty period for the PFM3350-1500 and where is it serviced?
Apsardze24.lv provides a 2-year warranty for both private and business customers. In the event of a technical issue, service is performed locally at our professional technical center in Riga.
Is this an official EU version compatible with 230V power grids?
Yes, this is the official CE-certified European version sold by Apsardze24.lv. It is specifically designed for 230V/50Hz power grids and includes fast shipping to Latvia, Estonia, and Lithuania.
Is the Dahua PFM3350-1500 safe for high-end gaming PCs with Active PFC power supplies?
Yes, this model produces a Pure Sine Wave output, which is the gold standard for sensitive electronics. Unlike simulated sine wave units, it is fully compatible with hardware featuring Active PFC power supplies, high-end servers, and medical equipment.
Can this UPS handle low or high voltage without draining the battery?
Yes, as a Line-Interactive UPS, it utilizes Digital Voltage Stabilization (AVR). It automatically adjusts voltage fluctuations within a range of 170V to 280V, maintaining a stable output without depleting the battery reserves.
Marcus Thorne –
This Dahua UPS is a solid bit of kit for my home office. The pure sine wave output gives me total peace of mind for my sensitive equipment. It’s remarkably quiet and feels very well-built. I’m quite impressed with the fast charging time and the excellent service from Apsardze24. Highly recommended!
