The Bluewalker Powerwalker voltage regulator AVR 1200 720W is an external voltage regulator for automatic stabilisation of mains voltage. It provides protection and supply security for sensitive electronic devices, particularly in environments with unstable or fluctuating voltages. The device operates with a power capacity of 720 watts / 1200 VA and is suitable for use in offices, home networks or small IT infrastructures where constant voltage supply is required.

Applications
This voltage regulator is designed for indoor use where mains voltage may fluctuate, for example in older buildings, heavily loaded power grids or regions with unregulated supply quality. It protects sensitive devices such as PCs, printers, routers, network equipment or small servers from voltage surges, under-voltage and over-voltage. The integrated automatic voltage regulation (Automatic Voltage Regulation, AVR) ensures that the output voltage is maintained within a tolerable range of ±12%, which is sufficient for most electronic devices.

Functions and equipment in detail
The device features an integrated disconnect switch, enabling safe disconnection. It provides standard overvoltage protection against sudden voltage spikes. Additionally, overload protection, short-circuit protection and thermal protection are integrated to safeguard the device and connected equipment. The energy rating is 430 joules, enabling absorption of short-term voltage spikes. The device is designed for an operating temperature of 0 °C to 40 °C and can be operated at a humidity level of 0 to 90 % (non-condensing).

Technology explained simply
The automatic voltage regulation (AVR) automatically adjusts the output voltage when the input voltage falls outside the tolerable range. The input voltage range is 180–264 V AC, with a nominal voltage of 220/230/240 V. The frequency must be 50 Hz. The output voltage is stabilised to ±12%, meaning that with a nominal voltage of 230 V, the actual output voltage can range between approximately 205 V and 255 V. This range is sufficient for most electronic devices to operate safely. The device is not designed for operation with direct current or other frequencies.

Compatibility and accessories
The voltage regulator is designed for use with devices requiring a nominal voltage of 220/230/240 V AC. It is not suitable for devices with special requirements regarding voltage waveform (e.g. pure sine wave) or for devices with high transient current surges (e.g. large motors). The device includes an integrated power cable for connection to the socket.

Installation and mounting
Installation is carried out by direct connection to a socket. The device is compact in size, with a width of 16.1 cm, depth of 16.6 cm and height of 8.7 cm. It is designed for stationary use on a flat surface. The shipping dimensions are 11.9 cm (width), 19.1 cm (depth) and 23.1 cm (height), with a shipping weight of 1.9 kg. The operating weight of the device is 1.7 kg.

Advantages in operation
The voltage regulator provides reliable stabilisation of mains voltage, thereby extending the service life of sensitive electronic devices. The integrated protection functions minimise the risk of damage from voltage surges, overload or short circuits. The simple operation and direct connection to the socket make the device particularly suitable for use in small offices or home applications. The warranty period is 2 years and includes a limited warranty for the device.
