Power-One Introduces ac-dc Front-End to Reduce Power Consumption
Power-One, Inc. introduced the FNP1500-12G ac-dc front-end; designed to reduce host-system power consumption by combining 90% efficiency with an output that is I2C programmable from 7-13Vdc. This wide adjustment range enables users to select a bus voltage that minimizes their system-specific I2R distribution losses and increases the efficiencies of downstream bricks and point-of-load converters. I2C adjustability provides the option to dynamically optimize the bus voltage in response to changing line and load conditions.
Additional I2C-interface capabilities include enabling the output, controlling internal fan speed, and setting the output current limit. Power supply management is also accomplished via front-mounted LED status indicators and a comprehensive range of logic signals. This hot-swap product incorporates internal ORing diodes and features an 85-264V input range, six-substance RoHS compliance, and a one-amp 12Vdc standby output. Protections include: output overvoltage, output overcurrent, and overtemperature.
An industry-leading power density of 15.2 W/in3 enables delivery of 126 amps from an ultra-compact 1.6" x 5.6" x 11" (40.5 x 141.2 x 279.4mm) package. Three FNP1500-12G front ends can be configured to provide 378 amps (4536W) from a 19-inch shelf. Please consult factory for shelf availability. Pricing is $263 each in OEM quantities. Evaluation models are usually available from stock. Production quantities are typically available in six to eight weeks. Power-One products power high-availability infrastructure applications such as: routers, data storage and servers, wireless communications, optical networking, medical diagnostic, railway controls, and semiconductor test equipment.
