SVEN Power Pro+ 400 line-interactive UPS copes excellently with its basic task – to save data and close the PC and its applications correctly in case an emergency situation in the electric power network occurs.

The battery’s capacity provides operation of the equipment at full load within 2.5 minutes, and at half-load – within at least 8 minutes. The built-in voltage regulator gives a possibility to increase/decrease voltage without entering battery operation mode and ensure long uninterrupted work. This feature is important for networks with unstable voltage. The nominal power of this UPS is 230 W.

Power Pro series is designed for protecting PCs, workstations, local network equipment, various IT equipment and computer systems:

Home Office;
Small Office;
Small/Medium Business.

An undoubted advantage of SVEN Power Pro+ 400 UPS is its price which, combined with excellent specifications, makes this model attractive for wide range of users. We recommend SVEN Power Pro+ 400 to home users for protection and long autonomous operation of Wi-Fi modems, satellite receivers, DVDs and LCD TVs. The model is also suitable for office workers (managers, accountants, etc.) where loss of unsaved data can lead to substantial expenses. Besides, SVEN Power Pro+ 400 can be recommended to home Internet providers for supporting power supply of remote network equipment, such as routers, located in places of buildings which are difficult to access. Pro+ 400 will guarantee self-contained work of security and fire prevention systems. When disconnected from the mains, Pro+ 400 will maintain operation of the equipment until the battery is flat, and when the power is on again, it will automatically supply the device with power and charge its battery.
