650-W front end power supply targets distributed power architectures

February 15, 2016 // By Paul Buckley
Murata has introduced the D1U54P-650-12-HBxC series of 650 W power supplies which delivers a power density of 21.4 W per cubic inch.  The compact power supply exceeds the 80 PLUS Platinum efficiency requirements.

Packaged in an industry standard 1U format measuring 54.5 x 40 mm and has a length of 228.6 mm.  Featuring a single 12 VDC primary supply it also provides a standby 12 VDC / 2 A output.

The hot pluggable units are capable of N+1 redundancy and feature an active current sharing (ORING FET) permitting connecting up to a maximum of eight in parallel.

Control features include an I2C compliant PMBus interface and front panel LED status indicators. Overvoltage, overcurrent and over temperature protection is included across the range.

Forced air cooling is facilitated by a low noise variable speed fan and the direction of air flow, front to back or back to front, can be specified at the time of order.

The D1U54P-W-650 is an AC input unit accommodating the full universal input range from 90 to 264 VAC. A DC input model, D1U54-D-650 is also available in same size.

The D1U54P-x-650 series is aimed at distributed power architecture applications and is ideal for use with networking equipment, server and storage systems.
