It incorporates resonant-soft-switching technology and interleaved power trains to reduce component stresses, providing increased system reliability and very high efficiency. With a wide input operating voltage range and minimal linear derating of output power with respect to ambient temperature, the PFE3000-12-069RA maximizes power availability in demanding server, switch, and router applications. The power supply is fan cooled and ideally suited for server integration with a matching airflow path. The PFC stage is digitally controlled using a state-of-the-art digital signal processing algorithm to guarantee best efficiency and unity power factor over a wide operating range. The DC-DC stage uses soft switching resonant techniques in conjunction with synchronous rectification. An active OR-ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. The always-on +12V standby output provides power to external power distribution and management controllers. Its protection with an active OR-ing device provides for maximum reliability. Status information is provided with front-panel LEDs. In addition, the power supply can be monitored and controlled (i.e. fan speed 2 setpoint) via I C communication interface with Power Management Bus protocol. It allows full monitoring of the supply, including 2 input and output voltage, current, power, and inside temperatures. The same I C bus supports the bootloader to allow field update of the firmware in the DSP controllers. Cooling is managed by a fan, controlled by the DSP controller. The fan speed is adjusted automatically depending on the actual 2 power demand and supply temperature and can be overridden through the I C bus.
