The new DS Power range UPS uses the latest DSP technology to be programmed to suit a wide variety of electrical environments without impending its performance. It can be paralleled up to three units to achieve the maximum power of 1.8 MVA. With the DS Power range, efficiency, reliability, and functionality are enhanced to levels unattainable with the old analogue technology. This technology does not only create a significant increase in MTBF, but the capability of DSP to accurately manipulate signals at very high speed permits all the UPS subsystems to be controlled with greatly increased precision.
