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. It’s new high frequency design means the use of less copper is used which results in a smaller overall size and leads to the use of less plastics and less enegy to ship it. Advanced features like Master/Controlled outlets that shut off power to printers, scanners and speakers when the computer is not in use saves 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 competitive products.
