  • Transformer-free UPS
    Transformer-free KR33 BM Series (300-800kVA)
    3 Phase Online Transformer-free UPS (300-800kVA) The KEHUA high frequency IGBT rectifier uses 3 level dual-converter online technology, IGBT, and DSP (digital processing processors). The KR(/B)33-BM series ensures high quality electricity is provided to any data processing or industrial load and is particular applicable to the protection of important key loads. VFISS 11 (voltage, frequency independent) complies with IEC EN 62040-3. The design of this series uses a new configuration which includes replacing the traditional SCR rectifier with a IGBT rectifier which ensures sinusoidal input current. At the same time, the 300kVA and above compatible isolation converter enables complete electrical isolation between output and input and completely prevents any disturbance to the load equipment brought about by power grid abnormalities of the input.
