The Back-UPS ES 750 VA includes the same highly efficient charging system and modern look as the ES 650, but it also has other "green" features designed to minimize environmental impact while still offering the world's most reliable power protection for computer systems and peripherals. Its new high frequency design means it uses less copper, which results in smaller overall size and leads to the use of less plastics and less energy to ship it. Advanced features, such as the Master/Controlled outlets that shut off power to printers, scanners and speakers when the computer is not in use, save additional money on electric bills and proves that it is possible to reduce electrical waste and still deliver up to 5 times more efficiency than competing products. Features: Ten surge protected outlets, 5 with battery backup Included PowerChute safe system shutdown software Full dataline protection 3-year warranty
