The Rotoups rotary uninterruptible power supply series is available in single- and three-phase input and output voltages and frequencies in power ratings from 5 to 1000 kilovolt-amperes. Its motor generator, in combination with other system elements, produces a harmonics-free sinewave output and isolation between the input and output. The system`s three main elements--the rectifier-inverter control unit, the motor-generator unit, and the battery pack--can be housed separately. Prices range from $21,995 to $370,496.
