SVEN Pro+ 650 (LCD, USB)

Remember this product

SVEN Pro+ 650 line-interactive UPS is designed for protection of PCs, workstations, as well as servers equipped with switch power supplies. Due to its battery, the UPS can operate even in case of complete absence of mains power, which gives the user a possibility to save data and shut down the operating system correctly. The built-in automatic voltage regulator allows increasing/reducing the input voltage without switching to battery mode and ensures long uninterruptible work. This feature is vital for networks with unstable voltage.

SVEN Pro+ 650 UPS is supplied with Cold Start function, allowing to switch on the UPS in conditions of complete absence of mains voltage. The built-in USB port gives a possibility to monitor the mains from your PC and shut down the PC in automatic mode. Besides, The UPS is equipped with a multifunction LCD display showing the mains status, load and battery discharge level.
