APC recently unveiled some new uninterruptible power supplies (UPS) units which it says are more energy efficient. These models are part of the APC Back-UPS ES line up and range from around $45 to $100.

APC said the APC Back-UPS ES line uses charging technology “which allows the product’s master outlet to sense when the computer has either been turned off or has gone into sleep mode, so it can shut off power to unused peripherals plugged into the controlled outlets.” The APC Back-UPS ES 450, 550 and 650 models feature eight surge protected outlets, with four of the outlets also providing battery backup. The APC Back-UPS ES 750 offers ten surge protected outlets, with five of the outlets also providing battery backup. There is also a 350 model that features six surge protected outlets.

How would you like to own an uninterruptible power supply which is geared towards helping you save electricity? It’s an interesting concept APC is exploring as it unveils its Back-UPS ES 750 for around $100.

The APC Back-UPS ES 750 lets you plug up to 10 devices into its outlets. Five of these plugs offer battery backup up to 70 minutes in case power fails and all 10 offer surge protection as well. As an eco-friendly device the ES 750 has master/controlled outlets in which the master, sensing a computer has gone into sleep mode or powered off, automatically shuts down the controlled outlets. This in turn powers connected devices, saving money and cutting down on power usage.
