SVEN Pro+ 800


SVEN Pro+ 800 line-interactive UPS is designed for protection of PCs, workstations, as well as servers equipped with switched mode power supplies. Due to its battery, the UPS can operate even in case of complete absence of mains power, which enables the user to save data and shut down the operating system correctly. The built-in automatic voltage regulator enables you to increase/reduce the input voltage without switching to the battery mode and ensures long uninterruptible work. This feature is vital for networks with unstable voltage.

SVEN Pro+ 800 UPS is supplied with Cold Start function, enabling the user to force the UPS into operation in complete absence of mains voltage.
