The APS4000 Simulation Software is designed for simulating power systems used in aviation and marine equipment. It integrates with ITECH IT7800/IT7900P high-performance AC/DC power supplies to provide a broad range of output options (5kVA to 960kVA, 16Hz to 2400Hz). The software includes built-in standards for military and commercial aircraft power supply characteristics (e.g., MIL-STD-704, DO160, A350, A380) and enables realistic reproduction of various AC and DC power supply systems in aviation, including 270Vdc, 28Vdc, 115V/400Hz AC, and more. The user-friendly GUI ensures quick test setup and execution..
