This series of 19" Rack Sine Wave Inverters is a direct development of the Studer SI series. This range of inverters are well known for their outstanding reliability by professional users.The new series are built for 19'' rack users and therefore well suited for industrial and professional applications.The frequency output is 50Htz/230VAC(Crystal control) and 12vdc, 24vdc and 48vdc input. The inverters deliver a high and steady efficiency,outstanding overload capability thanks to the combined use of a toroidal transformer and a MOS power stage and ultra-fast regulation.

Other featues include overload,overheat,short-circuit and reverse polarity protection;adjustable stand-by-level from a low threshold and no noise thanks to HF-switching > 20 kHz.The SI 1200w IND version allows the possibility to configure 3 inverters (min. SI 1200 IND) in a 3-phased 3 x 400V stand-alone grid.

There are a number of options such as 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.An alarm option with no potential (0,5A - 60V) is available. It warns the user (alarm or control system) when the inverter has been stopped due to a failure or is out of use. It is off when the inverter is working.The inverters are virtually maintenance free.These inverters are available now.
