Murata has announced the D1U54P-W-1500-12 series of 1500 Watt power supplies manufactured by Murata Power Solutions. Packaged in an industry standard 1U format measuring 54.5 × 40 mm (2.15 1.57 inches), it has a length of 12.66 inches, the same as the 1200 W and 1300 W power supplies in this family. Delivering a power density of more than 35 Watts per cubic inch, this compact power supply exceeds the 80 PLUS Platinum efficiency requirements. Featuring a 12 VDC main output, it also provides optional standby outputs of 12 VDC, 5 VDC, or 3.3 VDC output.
These hot-pluggable units are capable of N+1 redundancy and feature active current sharing (ORING FET) permitting connection of up to eight in parallel.
Control and monitoring features include an I2C compatible 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; the direction of air flow, front to back or back to front, can be specified at the time of order.
The D1U54P-W-1500-12-HxxTC is an AC input unit accommodating the full universal input range from 90 to 264 VAC. A DC input model, D1U54-D-1500-12-HxxC, is also available in the same size.
The D1U54 series is targeted for power architecture applications and is ideal for use with networking equipment and server and storage systems.
