ABSOPULSE Electronics’ 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. DC-input voltages include 24V, 36V, 48V, 125V or 250Vdc. Other input and output 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.
