The CSI 1K-3U2 and CSI 1K-3U3 series rugged, modular DC-AC inverters deliver up to 1kVA sine wave output voltage. The use of the latest silicon carbide (SiC) semiconductor technology contributes to high conversion efficiency, high power density and a compact form factor. The inverters are suitable for a broad range of heavy-duty industrial applications that require clean, stable AC-power.

The sine wave inverters provide a single, regulated pure sine wave output of 115Vac continuous at 400Hz or 60Hz, or 230Vac continuous at 50Hz. Standard DC-input voltages include 24V, 36V, 48V, 125V or 250Vdc. Other I/O voltages are available on request. High performance filters on the input and output ensure low noise; the input meets EN55032 Class A with wide margins.

The inverters comply with C22.2 No. 107.1-01, UL458 and EN62368-1 and equivalent internationally recognized industrial safety standards. Electronic protection includes 1700Vdc input to output isolation (which may differ depending on the voltage requirements), protection for overload, over voltage, short-circuit and inrush current.

High quality built-in fans and additional conduction via the baseplate provide sufficient cooling ensure 1000VA continuous operating power over a 0°C to +50°C operating temperature range without de-rating.  Extended temperature ranges and conformal coating are available for operation in severe environments. An output fail alarm (Form C) are  available on request.
