Rack-Mount Front Ends

Power-One’s comprehensive array of rack-mount front ends utilize high-efficiency topologies, and advanced thermal-management techniques, to provide industry- leading power densities and energy savings.

Robust feature sets include standby outputs, parallel/redundant and hot-swap capabilities, ultra-compact packages with front-panel status LEDs, wide input-voltage ranges, a complete range of logic signals, and extensive I²C interface monitoring and control.

Backplane and Front-Mounted AC Inputs
and Common-Footprint DC-Input Solutions

AC connection options include backplane-mounted hot-swap connectors and front-mounted IEC receptacles.

Selected products utilize the same packaging and backplane connectors for both AC-input and DC-input versions. This common-package approach facilitates DC-input front ends that will operate in existing AC-input systems with minimal rack hardware changes.

In addition to providing best-in-class front-end power-conversion efficiencies, Power-One’s front ends are designed to reduce system-level power consumption.

• A broad selection of output voltages can reduce the cost and space required for downstream power conversion to application specific voltages, such as 32V to power RF amplifiers.

• Wide adjustment ranges enable users to select a bus voltage that minimizes their system-specific I²R distribution losses and increases the efficiencies of downstream DC-DC converters.
• I²C adjustability provides the option to continuously adjust the output of the front end, optimizing the bus voltage in response to dynamic operating conditions to further reduce I²R distribution losses and increase power-converter efficiencies.
