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
