This power supply is the core power conversion component of a 5kW AC-DC power supply system used in a shipboard environment. Primary input power is MIL-STD-1399 3 phase, 440Vac, 60Hz with multiple isolated 280VDC and 28VDC output voltages. A modular design enables optimum power configurations based on system requirements. Active PFC circuitry provides excellent EMI performance and immunity to input voltage transients. Internal energy storage provides over 50msecs of hold time.
