Eaton Corporation has released the Eaton 9E uninterruptible power supply (UPS), a highly efficient backup power device designed specifically with the information technology (IT) manager in mind. The 9E’s sleek, compact tower configuration delivers superior power protection for expanding loads in space-constrained data centers while operating at up to 98 percent efficiency, making it the most efficient UPS in its class. The 9E is the first UPS in its class to offer internal batteries up to 60 kVA, which saves significant floor space when compared to external battery cabinets.
