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. (Option -PE).
• A range in 19’’ rack is also available from 1200 to 3500W (see option SIxxxxIND).
