Three-phase UPS with output Isolation Transformer
SII provides maximum protection for vital‚ mission-critical applications e.g. data-centres, security systems, medical systems, industrial applications. Thanks to its outstanding mechanical
and electrical design.
The SII series includes a power range from 100 to 800kVA with three phase input and output. The SII uses double conversion on-line technology (VFI) with an isolation
transformer on the output of the inverter. The load is powered continuously by the inverter with a filtered, stabilised and regulated sine-wave supply. The input and output EMI filters considerably increase the immunity of the load to mains disturbances and surges.
