BCD.00420 AE PET 1300 - 12 - 054 X A Airflow Product Family Power Level V1 Output Width Input Dash Dash N: Normal PET Front-Ends 1300 W 12 V 54 mm A: AC R: Reversed The PET1300-12-054xA AC/DC power supply is a fully DSP controlled, highly efficient front-end power supply. It incorporates resonance-soft-switching technology and interleaved power trains 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 PET1300-12-054xA 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 is an analogue solution MCU is used to communicate with DSP chip on secondary side. 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 hence it is ideally suited for operation in redundant power systems. The always-on standby output with voltage level (3.3 Volts), 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 front-panel LEDs. In addition, the power supply can be controlled and the fan speed set 2 2 via the 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 2 actual power demand and supply temperature and can be overridden through the I C bus.
