Nova Electric offers a full array of Rugged True Online UPS Systems to suit any commercial, industrial, or military application, including those that require UPSs which can withstand Military Environmental and Electrical Standards such as MIL-STD-810, MIL-STD-901, MIL-STD-167, MIL-STD1399, MIL-STD-461, and more. These Rugged UPS Systems are available in rack mount, freestanding or wall-mount NEMA cabinet, and custom enclosure configurations to suit applications with tight space constraints. Any standard voltage (single or three-phase) can be accommodated, in 50, 60, or 400 Hz frequencies, and most models can also act as Frequency Converters, changing a given input voltage and frequency to a different pure sinewave output voltage and frequency in conjunction with the usual battery back-up capabilities . Finally, all Nova Electric Rugged True Online UPS Systems feature our truly Rugged UPS modular design and robust construction, for many years of reliable performance, as well as the resulting low MTTR, MTBF, and Cost-To-Own figures.
