UPS POWERWALKER VI 1500 STL 1500VA Line Interactive

POWERWALKER VI 1500 STL is a line-interactive UPS with a capacity of 1500VA, aimed at home and small office configurations that want stable power without unnecessary complexity. You get four Schuko outputs, an LCD display for easy control, and operation with PowerMaster monitoring software via USB. At 50% load, it provides about 7.5 minutes of battery runtime – fully sufficient for a normal shutdown of PC, NAS, and router. The output voltage waveform is simulated sine wave, making it a logical choice for standard power supplies and office equipment.

What you get

With a capacity of 1500VA, you can safely connect a desktop PC, monitor, router, and another 1-2 lighter consumers, with the UPS providing about 7.5 minutes of autonomy for saving and controlled shutdown at around half load. The two internal batteries 12V / 7.2Ah charge up to 90% in about 8 hours, so it is fully ready for the next outages overnight. The line-interactive topology maintains stable output voltage in the input range of 162–290 VAC, which helps during dips and spikes in the grid without constant battery switching. Through the USB connection and PowerMaster software, you can monitor the load, battery status, and automate the shutdown of the machines. The LCD panel provides a quick glance at the main parameters – input/output voltage, load, and operating mode.

• Line-interactive UPS with a capacity of 1500VA, suitable for protecting desktop PCs, small servers, or office equipment during power outages and dips.
• Four output connectors CEE 7/3 (Type F), allowing you to directly connect several devices without additional adapters.
• Two internal batteries with model 12V / 7.2Ah, providing about 7.5 minutes of operation at 50% load for safe saving and shutdown.
• Wide input voltage range of 162–290 VAC and input frequency 50 or 60Hz, making it resilient to unstable electrical networks.
• Simulated sine wave output, suitable for standard power supplies and office equipment without sensitive loads to pure sine wave.
• USB connection and PowerMaster software for monitoring and automatic shutdown of systems during longer outages.
• LCD control panel for easy monitoring of status, battery level, and load, with noise below 45 dB and weight around 9.1 kg.

Who it is suitable for

This UPS is a good choice for home and small office configurations with 1–2 stationary computers, NAS, router, and peripherals, where it is important to avoid sudden shutdowns and data loss. It is suitable if you want basic protection and time to normally shut down your systems without investing in a more expensive online UPS. It is not the best option if you work with very sensitive laboratory equipment or devices that require a pure sine wave.

The combination of 1500VA capacity, four Schuko outputs, LCD display, and software control via USB makes POWERWALKER VI 1500 STL a practical and balanced UPS for everyday protection of your equipment. You can rely on stable performance during network disturbances without dealing with unnecessary settings.
