The Bluewalker UPS Powerwalker VI 2000 LCD is an external uninterruptible power supply (UPS) with a power capacity of 1.2 kW / 2000 VA, designed for use in office environments, server rooms, or with sensitive IT and electronic equipment. The device operates using Line-Interactive technology, in which the mains voltage is continuously monitored and stabilized during deviations by automatic voltage regulation (AVR), without immediately switching to battery operation. This ensures efficient energy usage and extends the lifespan of the integrated battery. The output voltage is 220/230/240 V ± 10 % at a frequency of 50/60 Hz, with the waveform gradually approaching a sine wave, making it suitable for powering sensitive devices.

Applications
This UPS is suitable for operating computers, network devices, printers, monitors, and other electronic equipment requiring stable and uninterrupted power supply. The integrated AVR function protects against voltage fluctuations in the public power grid, which is particularly beneficial in regions with unstable electricity supply. The devices are designed for indoor use, with an operating temperature range of 0 °C to 40 °C and humidity of 0 to 90 % (non-condensing). The noise level is 40 dB, ensuring quiet operation in offices or workspaces.

Functions and Equipment in Detail
The device features four output sockets in CEE 7/7 (SCHUKO) format, suitable for powering multiple devices. The integrated battery has a capacity of 9 Ah and provides a voltage of 12 V. The UPS includes an audible alarm that signals power failure, overload, or low battery charge. An LCD display informs the user about operating status, remaining runtime, and current voltage. Additional protection functions include discharge protection, overcharge protection, and overload protection, enhancing battery safety and lifespan. The cold start function allows the device to be started even without mains power, which is useful in emergencies or after power restoration.

Technology Explained Simply
The Line-Interactive technology means that the UPS continuously monitors the mains voltage. For minor fluctuations, the voltage is regulated via the AVR function without activating the battery. Only in the event of a complete power failure or severe voltage fluctuations does the UPS switch to battery operation. The response time for voltage regulation is 2 ms, which is sufficient for most IT devices to ensure safe operation. The output waveform is a gradual approximation to a sine wave, which is adequate for most electronic devices, although not for devices with very high power quality requirements.

Compatibility and Accessories
The UPS is equipped with a USB port (Type B, 4-pin) enabling remote management. The included ViewPower software allows monitoring and control of the UPS via a computer. The package includes a USB cable and three power cables necessary for connecting devices and preparing for mains connection. The integrated surge protection function protects connected devices from voltage spikes, particularly via telephone lines (RJ-11). The devices are suitable for use with standard network cables and IT equipment.

Mounting and Installation
The UPS is designed as a desktop unit and requires no special mounting. Dimensions are 14.6 cm (width) × 39.7 cm (depth) × 20.5 cm (height), with a weight of 12.1 kg. Shipping dimensions are 23.5 cm (width) × 49.5 cm (depth) × 28.5 cm (height), with a shipping weight of 13.2 kg. Installation involves connecting to the mains supply and then linking the protected devices to the output sockets. The ViewPower software can be installed and configured via the USB cable.

Operational Advantages
Operation of the Bluewalker UPS Powerwalker VI 2000 LCD is particularly user-friendly due to the combination of AVR, battery protection functions, and the LCD display. The integrated software enables detailed monitoring and control, which is advantageous for IT managers. The devices are designed for use in offices and small server rooms, where reliable power supply for IT infrastructure is critical. The 2-year limited warranty provides additional security for operation.
