The PES1600-12-080NA is a 1600 Watt AC to DC, power-factor- corrected (PFC) power supply that converts standard AC power into a main output of +12 VDC for powering intermediate bus architectures (IBA) in high performance and reliability servers, routers, and network switches. The PES1600-12-080NA utilizes full digital control architecture for greater efficiency, control, and functionality. This power supply meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD). Designed to meet Intel CRPS compatibility Best-in-class, meet 80 plus Platinum efficiency Auto-selected input voltage ranges: 90-140 VAC, 180-264 VAC AC input with active power factor correction 1600 W continuous output power capability Always-on 12 VSB / 3.5 A standby output Hot-plug capable Parallel operation with active current sharing Full digital controls for improved performance 3 High power density design: 42 W/in Small form factor: 195 x 80 x 40 mm (7.68 x 3.15 x 1.57 in) Power Management Bus communications protocol for control, programming and monitoring Status LED with fault signaling Networking Switches Servers & Routers Telecommunications 2 PES1600-12-080NA PES 1600 - 12 - 080 N A x Product Family Power Level Dash V1 Output Dash Width Airflow Input AC Inlet Blank - C20 PES Front-Ends 1600 W 12 V 80 mm N: Normal A: AC P - C22 The PES1600-12-080NA AC/DC power supply is a fully DSP controlled, 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 the PES1600-12-080NA 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 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 standby output provides power to external power distribution and management controllers. It is protected with an active OR-ing device for maximum reliability. Status information is provided with a front-panel LED. In addition, the power supply can be controlled and the fan speed set via the 2 2 I C bus. 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 2 power demand and supply temperature and can be overridden through the I C bus.
