Studer SI Sinewave Inverters
The SI range consists of sine wave inverters that convert the DC voltage of a battery into AC voltage which can be used by all electrical appliances.
Features and performances - High efficiency.
- Outstanding overload capabilities thanks to the combined use of a toroidal transformer, of an oversized power stage and of an ultra-fast regulation.
- Electrical supply to any kind of appliance.
- Full internal protection.
- Stand-by level adjustable over a large range and from a very low threshold.
- Reliable and silent working with all kind of loads.
- Possibility in option to connect 3 inverters together in an autonomous 3 x 400Vac 3-phase grid.
- Built-in solar charge controller in option for solar systems (only SI 600 and 800).
- A range in 19’’ rack is also available from 1200 to 3500W (see option SIxxxxIND).

Option TWINPOWER
From 1200W there is a possible choice between a stand-by system (load detection adjustable from 0.3 to 20W) and the unique TWINPOWER option. The TWINPOWER option enables the permanent use of very small loads (like alarms or security systems) with an outstanding efficiency, 10 times higher than any other inverter, and a no-load consumption < 0.5W (see above Options and accessories). |

Industrial casing in 19’’ rack
The availability of the inverters in 19’’ rack, from the SI 1200, is a direct evolution of the sine wave SI series and it meets particularly well the industrial applications (see above Options and accessories). | |
3-phase
With the PE option, and from the SI 1200, it is possible to connect 3 inverters together to build a 3 x 400Vac 3-phase grid. This extends the SI range up to 10500VA (3 x SI 3548 PE). Such a configuration enables to supply motors and other 3-phase equipments, even with asymetrical powers on the phases (see above Options and accessories). |
