The MBC600 Series AC-DC/DC-DC power supply can operate using AC or DC input. It is a highly efficient frontend power supply. The PFC stage adopts an analog controller in continuous conduction mode to achieve high power factor and high efficiency. The DC/DC stage is fully DSP controlled and employs soft switching resonant techniques in conjunction with synchronous rectification for high efficiency and better thermal control. With a wide input operational voltage range and minimal linear derating of output power with temperature, the MBC600 Series maximizes power availability in demanding server, network, and other high availability applications. The supply is convection cooled or fan cooled and ideally suited for integration with a matching airflow path.
