Záložný zdroj PowerWalker VFI 3000 TG

The PowerWalker VFI 3000 TG is a 3000VA / 2700W double-conversion online UPS designed for home and office environments. It provides continuous, regulated power with a power factor of 0.9 and comes with internal batteries (6 × 12V/9Ah). The unit includes a C20 input, four IEC C13 outlets and one IEC C19 outlet, USB HID support and a wide input voltage range of 100–300VAC. The tower form factor, active cooling and included power and USB cables make it suitable for protecting servers, workstations and critical devices from power disturbances.

Advantages

Online double-conversion topology ensures a stable, clean sine-wave output and zero transfer time to battery. Integrated batteries and optional long-run configuration with a stronger charger provide flexibility for internal or external battery setups. HID compliance allows the UPS to be recognized by operating systems without additional software, simplifying monitoring and management. Wide input range and a 0.9 power factor improve compatibility with varied electrical environments and connected loads.

Suitable for

• Small servers and network equipment
• Workstations and desktop PCs
• Point-of-sale systems, kiosks and ATMs
• Home office and business-critical devices
• Applications requiring software-free UPS detection (e.g., banking)

How to use

Install the UPS on a stable, well-ventilated surface and connect the C20 input to a properly grounded mains outlet. Connect critical devices to the IEC C13 and C19 outlets and attach the included USB cable to enable HID communication with the operating system for automatic detection. For extended runtime, configure an external battery pack with the stronger charger option if available and follow the manufacturer's battery connection instructions. Verify LED indicators and perform a controlled shutdown test to confirm correct operation and runtime.

Recommendations

Place the UPS away from direct heat sources and moisture, keep ventilation openings clear, and perform periodic battery checks. Replace batteries according to the manufacturer’s schedule or when runtime degrades significantly. For installations in high-security environments where additional software is restricted, rely on USB HID monitoring and local procedures for graceful shutdowns.
