Prowave DS300 300-600KVA



Prowave DS300
Uninterruptible Power Supplies
3phase in/3 phase out (300-600KVA)


The new ProWave DS/Power range UPS uses the latest DSP technology to be programmed to suit a wide variety of electrical environments without impending its performance. 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 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.
