The CSI 1K-3U2 & CSI 1K-3U3 series of rugged, modular DC-AC inverters deliver a 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, 250Vdc or custom. The inverters are suitable for a broad range of heavy-duty industrial applications that require clean, stable AC-power.
