The PET2000-NAS446 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-NAS446 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.

The always-on standby output provides power to external power distribution and management controllers.

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

Stresses in excess of the absolute maximum ratings may cause performance degradation, adversely affect long-term reliability and

cause permanent damage to the supply.
