EVI 850VA / 480W Line Interactive UPS – AVR, Cold Start & Smart Battery Management EP-UPS850UU2-UK

The EVI 850VA / 480W Line Interactive UPS is a reliable and efficient line-interactive UPS designed to provide stable backup power and protection for desktops, routers, networking equipment, small servers, and office systems.

With an 850VA / 480W capacity, it delivers dependable power support for home offices, small businesses, surveillance systems, POS terminals, and other critical electronics during power interruptions and voltage fluctuations.

Built with line-interactive topology and integrated AVR (Boost & Buck) technology, the UPS automatically regulates voltage levels by correcting under-voltage and over-voltage conditions without relying heavily on battery power. This helps maintain stable output power while improving battery efficiency and extending battery lifespan.

The cold-start function allows the UPS to power connected devices directly from battery mode even when there is no mains electricity available, ensuring continued operation during complete outages.

The UPS also features intelligent battery management with smart charging and discharge controls that optimize battery performance and enhance long-term reliability. Its simulated sine wave output makes it suitable for most home and office electronics while providing safe and consistent backup power during outages.

With a fast transfer time of approximately 2–6 milliseconds, the UPS ensures smooth switching from utility power to battery backup with minimal interruption to connected devices.

Designed for convenience and versatility, the UPS includes two universal output sockets compatible with a wide range of devices and plug types.

It also offers comprehensive protection features including overload protection, short-circuit protection, surge protection, and stable voltage regulation to safeguard connected equipment from electrical damage.

The compact tower-style design allows easy placement beside desks, workstations, or network racks without occupying much space.

Combining reliable performance, smart power management, and strong protection features, this UPS is an ideal backup solution for both personal and professional environments.
