PFE3000 AC/DC Power Supply

Bel Power Solutions fully-DSP-controlled, highly-efficient PFE3000-12-069RA AC-DC/DC-DC power supply

Bel Power Solutions PFE3000-12-069RA AC-DC/DC-DC power supply is a fully-DSP-controlled, highly-efficient front-end. The device 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 operating voltage range and minimal linear de-rating of output power with respect to ambient temperature, the PFE3000-12-069RA maximizes power availability in demanding server, switch, and router applications. The front-end is fan cooled and ideally suited for server 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 12 V standby output provides power to external power distribution and management controllers. Its protection with an active OR-ing device provides for maximum reliability.

Status information is provided with front-panel LEDs. In addition, the power supply can be controlled and the fan speed set via the I²C bus. It allows full-monitoring of the supply, including input and output voltage, current, power, and inside temperatures. For customers seeking a best-in-class, 80-PLUS certified Platinum-level efficiency power supply Power-One offers the PFE Series of front-ends. The PFE Series of front-end power supplies offers a range of output power options at 600 W, 850 W, 1100 W, and 3000 W, PFC, as well as wide-input voltage ranges of 90 to 264 VAC and 5.0 V or 3.3 V pin-selectable standbys.
