Bel Fuse PET2000-12-074NA

PET2000-12-074xA is a 2000 Watt AC to DC, power-factor corrected (PFC) power supply that converts standard AC power into a main output of +12 VDC. PET2000-12-074xA 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). The PET2000-12-074xA 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 PET2000-12-074xA 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 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.
