Оnline UPS SIP380B20BD.9-33 double conversion with a three-phase input and output, with a total power of 20 kVA and with the connection of external battery cabinets. Transformer inverter for galvanic isolation. Output power factor 0,9. Parallel operation of up to four UPS. Compatible with generator sets and have high overload capacity.


  • Output power factor 0.9 provides active power up to 18 kW
  • System with three-phase output voltage and zero switchover time to batteries
  • Additional load protection - integrated inverter transformer provides galvanic isolation in linear mode
  • Power up or redundancy N + x by parallel connection of up to 4 devices
  • As part of a parallel system, it is possible to work with common or separate battery cabinets
  • Minimal load on the mains or generator due to the low input harmonic distortion coefficient
  • Input filter to reduce the impact on the mains
  • Output transformer for galvanic isolation of input and output


  • Control interfaces: RS-232/485, slot for cards SNMP and dry contacts
  • Emergency power off (EPO)
  • Graphic LCD and LED mnemonic panel

Installation and operation
