SI Series Pure Sinewave Inverters

The SI series offer:

  • A high and steady efficiency
  • An outstanding overload capability, thanks to the combined use of a toroidal transformer and MOS power stage
  • An ultra-fast regulation
  • An electrical supply to any kind of device
  • A complete internal protection of the SI (overload, overheat, short-circuit, reverse polarity)
  • A stand-by level adjustable on a large range and from a low threshold on
  • No noise thanks to HF-switching > 20kHz
  • The possibility to assemble 3 inverters (min SI1200) in a 3-phased 3x400C stand-alone grid
  • Twin-power option available, which enables the permanent use of very small loads (like alarms and security systems) with outstanding efficiency
