The PFE1300-48-054NA is a 1300 Watt AC to DC power-factor- corrected (PFC) power supply that converts standard AC mains power into a main output of 48 VDC for powering intermediate bus architectures (IBA) in high performance and reliability servers, routers, and network switches. The PFE1300-48-054NA meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD). Best-in-class, Platinum efficiency Wide input voltage range: 90-264 VAC 3 High Power Density design: 30.25 W/in Small form factor: 321.5 x 54.5 x 40 mm (12.66 x 2.14 x 1.57 in) AC input with power factor correction Always-On 16.5 W programmable standby output (3.3/5 V) Hot-plug capable Parallel operation with active digital current sharing 2 I C communication interface for control, programming and monitoring with Power Management Bus protocol Over temperature, output over voltage and over current protection 256 Bytes of EEPROM for user information 2 Status LEDs: AC OK and DC OK with fault signaling High Performance Servers Routers Switches 2 PFE1300-48-054NA PFE 1300 - 48 - 054 N A Product Family Power Level V1 Output Width Airflow Input Dash Dash PFE Front-Ends 1300 W 48 V 54 mm N: Normal A: AC *PFE1300-48-054NAS407 has black front panel with white text The PFE1300-48-054NA AC/DC power supply is combination of analog and DSP control, highly efficient front-end power supply. It incorporates resonance-soft-switching technology to reduce component stresses, providing increased system reliability and very high efficiency. With a wide input operational voltage range and minimal linear derating of output power with input voltage and temperature, the PFE1300-48-054NA maximizes power availability in demanding server, network, and other high availability applications. The supply is fan cooled and ideally suited for integration with a matching airflow paths. The PFC stage 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 standby output, with selectable voltage level (3.3/5.0 Volts), provides power to external power distribution and management controllers. It is protected with an active OR-ing device for maximum reliability. 2 Status information is provided with front-panel LEDs. In addition, the power supply can be controlled and the fan speed set via the I C bus. 2 The I C bus allows full monitoring of the supply, including input and output voltage, current, power, and inside temperatures. Cooling is managed by a fan controlled by the DSP controller. The fan speed is adjusted automatically depending on the actual power 2 demand and supply temperature and can be overridden through the I C bus. Figure 1.
