The Bluewalker PowerWalker VFI 10000 TGS PF1 is a single-phase online UPS in tower format, operating with True-Double-Conversion technology. The device is designed for use in critical IT and electrical installations where continuous, uninterrupted power supply is required. With a power capacity of 10,000 VA / 10,000 W, it provides sufficient energy for multiple servers, network devices, or other sensitive equipment. The UPS is specifically designed for operation with external battery packs, allowing the runtime during a power outage to be customized individually. The package includes the UPS, an operating manual, a USB cable, protective plates and screws for the parallel port, a dry contact connector, and a parallel communication cable. Batteries are not included and must be purchased separately.

Applications
The VFI 10000 TGS PF1 is suitable for use in data centers, server rooms, medical facilities, industrial control systems, and other applications where a power interruption could lead to data loss or operational downtime. The online technology ensures that the load is always supplied via the inverter, regardless of the grid status, thereby fully compensating for voltage fluctuations, disturbances, and outages. The tower format allows for flexible placement, whether on the floor, in a cabinet, or in a rack with an appropriate adapter.

Features and Equipment in Detail
The device features an output power factor of 1.00, meaning it can deliver full rated power even under pure resistive loads (e.g., servers or network devices). The input voltage range extends from 160–276 V AC at 100 % load and from 110–160 V AC at loads between 50–100 %, ensuring stable operation even under fluctuating grid voltages. The output nominal voltage can be set to 208, 220, 230, or 240 V to adapt to local grid conditions. The UPS supports a USB interface that is HID-compatible, so no additional drivers are required. This enables easy communication with the connected system for monitoring and control.

Technology Explained Simply
The True-Double-Conversion technology ensures that the current always flows through an inverter, which converts it into a clean, constant voltage. This protects connected devices from voltage spikes, sags, and disturbances. In grid mode, energy is delivered to the load via the inverter, while the batteries are simultaneously charged via a charger. In the event of a power outage, the UPS switches seamlessly to battery operation, so the load does not experience any interruption. The efficiency in grid mode at full load is 95.0 %, in battery mode 93.0 %, and in ECO mode it reaches 98.0 %, ensuring efficient energy use.

Compatibility and Accessories
The UPS is designed for operation with external battery packs, which must be purchased separately. Using external batteries allows for extended runtime and flexible scaling of backup capacity. The UPS supports parallel connection via the integrated parallel port, enabling multiple units to be connected to increase total capacity or create redundancy. The package includes protective plates, screws, and a parallel communication cable. A dry contact connector is also included to connect external alarm or control systems.

Installation and Mounting
The UPS is delivered in tower format and can be placed freely. Installation is performed using the designated terminal blocks and integrated connectors. The operating manual contains detailed instructions for mounting, configuration, and commissioning. Wiring is done via the designated power input and output terminals, ensuring correct polarity and grounding. Connection to the PC or server is made using the included USB cable.

Operational Advantages
The VFI 10000 TGS PF1 offers high output voltage stability and seamless transition in the event of a power outage. The high efficiency in ECO mode reduces energy consumption when the grid voltage is stable. The USB interface enables easy integration into existing IT systems. Support for external battery packs and parallel operation allows for flexible scaling and redundancy, which is advantageous for critical applications. The UPS is designed for indoor use, with no specific environmental temperature or humidity specifications provided in the package.
