UPS POWERWALKER VI 3000 STL

POWERWALKER VI 3000 STL is a line-interactive UPS with a capacity of 3000VA, aimed at more serious systems – powerful workstations, small servers, network equipment, or several heavier PCs. You get 4x CEE 7/3 (Type F) Schuko outputs, so you can directly connect your equipment without the need for exotic adapters. Management is convenient through the LCD control panel and PowerMaster software, so you always know what is happening with the load and the battery. The output voltage waveform is simulated sine wave, which is fine for most PC PSUs, routers, switches, and peripherals.

What you get
With a capacity of 3000VA, this UPS can comfortably handle several loaded machines or a combination of server, storage, and network equipment – the autonomy time will depend on how much you load them, but the idea is to give you enough time for controlled shutdown and protection from short outages. The four 12V/7Ah batteries inside, with a charging time of about 8 hours to 90%, are aimed at stability and faster recovery after longer power outages. The line-interactive type of operation and the input range of 162–290 VAC help smooth out fluctuations in the grid without constantly switching to battery. With an output voltage of 230 VAC and output frequency control in battery mode of ±1Hz, your electronics remain in a relatively “calm” mode instead of experiencing sudden shocks. The low noise level of < 45dB is a plus if you will keep it in an office or next to your desk, and the built-in alarm alerts you immediately in case of a problem, instead of finding out only when something shuts down.

• Line-interactive UPS with a capacity of 3000VA, suitable for more serious configurations, network equipment, and small server environments.
• 4x CEE 7/3 (Type F) Schuko outputs allow you to directly connect several devices without additional power strips with specific connectors.
• Internal batteries 4 × 12V/7Ah, providing stable power during grid outages and reasonable runtime for controlled shutdown.
• Input range 162–290 VAC and input frequency 50Hz or 60Hz, which helps the UPS adapt to an unstable grid without unnecessarily stressing the batteries.
• Output voltage 230 VAC and output frequency in battery mode ±1Hz, for more stable operation of connected equipment.
• Control panel with LCD and PowerMaster software, giving you a clear view of the status, load, and battery, as well as the ability for finer control.
• Noise level below 45dB and built-in alarm, so the UPS does not interfere in a work environment but alerts you in time in case of a problem.
• Charging time of about 8 hours to 90% and weight of 18.1 kg, which is normal for this class of UPS and indicates a serious battery block.
• No option to add additional batteries, which simplifies the system but means you need to plan the autonomy according to the factory configuration.
• Warranty of 24 months, providing peace of mind for longer-term use in an office or small business.

Who it is suitable for
It is suitable if you want reliable protection for several more serious machines, a small server, NAS, and network equipment, without entering the world of heavy online UPSs. A great choice for a small office, studio, home server, or gaming corner with several loaded PCs and peripherals. It is not for you if you are looking for a pure sine wave for more sensitive specialized equipment or the possibility of huge autonomy with external battery packs.

The combination of 3000VA capacity, convenient LCD panel, PowerMaster software, and low noise level makes it a balanced UPS for serious but still affordable protection of your equipment.
