The converter is a device that generates three-phase alternating current with a phase-to-phase voltage of 36VAC and a frequency of 400Hz. The converter is used to supply artificial horizons such as LUN 1202, AGK-47, AGK-47b and others operating under voltage of 3x36VAC. The converter requires a supply voltage in the range of 12 to 15VDC, e.g. 12V from the aircraft's mains.
