The HCI1335-2R2 is a DC-to-AC inverter distributed by Ferrocore. It is a high-efficiency, galvanically-isolated power converter intended for medical, broadcasting, and industrial applications. The device is able to take a nominal input voltage of 18 to 36 volts DC, and step it up to sine waveform output of 220 to 240 volts AC. It is rated for output power up to 1.5kVA, with a power factor of at least 0.9. The unit also supports many standard protections and fault-tolerance including under-voltage, overload, over-voltage, short-circuit, and reverse-polarity protection.
