The new Back-UPS ES 750 VA powers and protects computer systems and their peripherals from power related events. Additionally, it now contains new "green" features designed to reduce wasted electricity. These features include Master/Controlled outlets which will shut power off to computer peripherals like printers, scanners, and speakers when the equipment plugged into the master outlet is deemed not in use (i.e. asleep). The unit now also has a High Efficiency Design which makes the UPS between 3 and 5 times more efficient than competitive products. Customers can save up to $40 off of their annual electricity bill! This product is already award-winning! It was the winner of a CES Innovations 2008 Design and Engineering Award.
