The Bluewalker UPS Powerwalker VFD 600 CEE 7/3 300W is an offline uninterruptible power supply (UPS) designed for use in offices, home applications, or small server environments. The device provides power to sensitive electronic equipment during short-term power outages or voltage fluctuations. It features an internal battery and is rated for a power capacity of 300 W / 600 VA. Power output is delivered via a modified sine wave, which is sufficient for most IT and communication devices. The unit is black and has compact dimensions of 8.1 cm width, 23.1 cm depth, and 18.5 cm height, with a total weight of 3.1 kg.

Applications
This UPS is suitable for use with computers, printers, router or modem devices, and other sensitive electronic components that require protection against sudden power loss. The integrated data line protection via RJ-11 connectors safeguards network and telephone lines from overvoltage. The maximum operating temperature is 40 °C, the minimum temperature is 0 °C, and the operating humidity can reach up to 90 % (non-condensing). The device is therefore designed for indoor use within these environmental conditions.

Functions and Equipment in Detail
The device includes a disconnect switch as a safety circuit, enabling secure disconnection of the load from the mains. The internal battery has a capacity of 7 Ah and provides a voltage of 12 V. The charging time is 10 hours. The output voltage is AC 220/230/240 V ± 10 % at a frequency of 50/60 Hz. The input voltage range is AC 170 to 280 V, allowing high tolerance to voltage fluctuations in the public power grid. The cold start function enables the device to be switched on even with an empty battery, provided mains voltage is available.

Technology Explained Simply
Offline technology means that the load is normally supplied directly from the mains. In the event of a power failure, the UPS switches to the internal battery within a few milliseconds to avoid interruption of power supply. The output waveform is a modified sine wave, which is sufficient for most non-critical IT devices. Integrated protection functions include discharge protection, overcharge protection, and overload protection to safeguard the battery and device from damage. An audible alarm and LED indicators inform the user of the operating status, such as battery charge level, power failure, or faults.

Compatibility and Accessories
The device is equipped with two RJ-11 interfaces for network and telephone lines, providing surge protection. These interfaces are suitable for direct connection to modems, routers, or telephone systems. Power supply is via a CEE 7/3 plug, commonly used in Germany and other European countries.

Mounting and Installation
Installation involves connecting the devices to be protected to the output sockets of the UPS. Data lines are connected via the RJ-11 connectors. Power supply is provided through the CEE 7/3 plug into a mains socket. No special mounting instructions or tools are required. The device can be placed on a flat surface, ensuring sufficient ventilation space.

Advantages in Operation
The UPS provides reliable power during short-term outages and protects sensitive equipment from voltage spikes. The integrated protection functions extend the battery and device lifespan. Display and alarm functions enable easy monitoring of the operating status. The compact design and low weight facilitate placement in various environments.
