Murata launches 94% Platinum efficiency 1200 Watt power supply in 54mm form factor

by donpedro

Murata announced the D1U54P series of 54mm wide 1200 Watt front end power supplies from Murata Power Solutions. With industry leading efficiency of greater than 94% and a power density in excess of 28 Watts per cubic inch, these low profile units measure only 54.5 × 321.5 × 40 mm and fit the industry standard 1U package format. This high efficiency significantly lowers the cooling requirements and also contributes to power savings in customer applications. Additionally, the design offers at least 8% more power than leading competitors in the same form factor. The D1U54P series comprises two models, both providing a + 12VDC 1200 Watt output and an auxiliary +5VDC 15Watt output. The power factor corrected D1U54P series accommodates the universal AC input range from 90 to 264VAC. Forced air cooling is provided by an internal variable-speed fan. The series features a 0 to 60°C operating temperature range. The D1U54P series features hot-swapping and active current sharing for up to 8 supplies to be connected together.
Safety features include output overvoltage, output overcurrent, and self-resetting overtemperature protection. PMBus™ management and I2C interface with status indicators and boot loading are also available. Bi-Color LEDs on the front panel indicate the status of the power supply. The D1U54P series design utilizes a low component count, resulting in high reliability (MTBF 529K hours). Typical applications for the D1U54P series include data centers, servers, storage sub-systems, and data communications infrastructure equipment.
