UPS POWERWALKER VFI 3000 TG

POWERWALKER VFI 3000 TG is an on-line UPS with a capacity of 3000VA, aimed at serious configurations – servers, high-end workstations, network equipment, and sensitive devices. The On-Line topology and pure sine wave make it suitable for loads that do not tolerate compromises in power supply. You have clear control through the LCD panel and the ability to monitor via the Winpower software. This is a device for situations where you want network stability and safe shutdown, not just "to prevent the computer from shutting down".

What you get

The capacity of 3000VA gives you the ability to connect several more serious machines or a combination – server, storage, and network equipment, as long as you consider the load and connectors. At full load, you have about 3.9 minutes for controlled data preservation and shutdown, and at ~50% load, the time jumps to about 11.7 minutes, which is more than enough for short power interruptions and planned shutdowns. The built-in 6 batteries 12V/9Ah provide this buffer, with no option for adding external battery modules, so you know exactly what reserve you have. The input range of 176–300 VAC (and 80–285 VAC in bypass) plus the on-line design means that the UPS keeps the output stable even with quite "crooked" input. The pure sine wave and low voltage distortions protect sensitive PSUs and equipment that might otherwise behave unstably with cheap UPSs.

• On-line UPS with a capacity of 3000VA, suitable for servers, network equipment, and demanding workstations where continuous and clean power is critical.
• Output with pure sine wave and distortion of ≤2% for linear and ≤4% for nonlinear load, which is important for sensitive power supplies and precision equipment.
• Output connectors 4 x IEC C13 and 1 x IEC C19, providing flexibility for different types of devices – from servers to powerful PSUs.
• Runtime at full load 3.9 minutes and at 50% load 11.7 minutes, sufficient for buffering during short interruptions and safe shutdown.
• Total of 6 batteries 12V/9Ah with no expansion option, making capacity planning clear and predictable.
• Input voltage 176–300 VAC (and 80–285 VAC in bypass mode) and input frequency 40–70Hz, allowing operation in environments with unstable networks.
• Management via LCD control panel and Winpower software, so you can monitor status, load, and runtime in real-time.
• Built-in surge protection and weight of about 22.2 kg, typical for a dense on-line UPS with this class of batteries and power.

Who it is suitable for

This UPS is a sensible choice if you maintain a small server rack, an office with critical workstations, a studio, or a laboratory where even a short power outage is a problem. It is also suitable for a home rack/lab setup if you want on-line protection rather than basic line-interactive. If you need long autonomous time (tens of minutes to over an hour) for a large load and an option for battery expansion, you will likely miss such a possibility here.

The most sensible aspect of this model is the combination of on-line operation, pure sine wave, and 3000VA capacity with clear, predictable battery reserve and control via LCD and software – exactly what you want to keep important equipment stable in an unstable network.
