Studer SI Inverters
The SI series consist of "high end" pure sine wave inverters for AC voltage systems, and even allow to create a real 3-phased grid with 3 SI, from the 1200W unit. You can use the SI for any AC system in 230Vac (also in 115Vac/60Hz on request, up to 2300W). The SI benefits from our long experience in delivering a "one step ahead technology".
The SI series offer:
- * a high and steady efficiency
- * an outstanding overload capability, thanks to the combined use of a toroidal transformer and a 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)
- * an stand-by level adjustable on a large range and from a low threshold on
- * no noise thanks to HF-switching > 20 kHz
- * the possibility to assemble 3 inverters (min. SI 1200) in a 3-phased 3 x 400V stand-
- alone grid
- * an optional solar charge controller for solar powered systems (only with SI 600 and SI 800).
A 19" rack range is also available from 600 to 5000W (ask for option SIxxxxIND or HPSI serie).
Option TWINPOWER:
From 1200W there is a choice between a stand-by (load detection adjustable from 0,3 to 20W) and the unique TWINPOWER option.
The TWINPOWER option allows the permanent use of very small loads (like security and alarm systems), with an outstanding efficiency 10 times higher than any other inverter and a no-load consumption < 0,5W.
