On-line uninterruptible power supply DS POWER U1

three-phaseACVRLA

DS Power U1 On-Line UPS is designed for 110VAC - 60Hz systems. It uses the latest DSP technology to be programmed to suit a wide variety of electrical environments without impending its performance. With the 3-Level topology, efficiency, reliability and functionality have been raised to levels unattainable with legacy. This technology does not only create significant increase in MTBF, but the DSP’s ability to accurately procces signals at very to accurately manipulate signals at very high speed allows all the UPS subsystems to be controlled with greatly increased precision.
