The PES2200-12-080xD is a 2200 Watt DC to DC power supply that converts -40 to -75 VDC voltage into an insulated main output of +12 VDC for powering intermediate bus architectures (IBA) in high performance and reliability servers, routers, and network switches. The PES2200-12-080xD 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).

It incorporates state of the art technology and uses an interleaved forward converter topology with active clamp and synchronous rectification to reduce component stresses, thus providing increased system reliability and very high efficiency. With a wide input DC voltage range the PES2200-12-080xD 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. 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 I2C bus. The I2C 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 demand and supply temperature and can be overridden through the I2C bus. Figure 1.
