Pure sine wave DC/AC inverter CSI 1K-3U series

high-frequencyPWMfor industrial applications

The CSI 1K-3U2 and CSI 1K-3U3 series of 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.
