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.
