Front-end power supplies can form up to eight units in parallel
Packaged in an industry standard 1U format, measuring 54.5 x 40mm (2.15 x 1.57inch), the D1U54P-W-1500-12 series of 1500W power supplies are manufactured by Murata Power Solutions.
They deliver more than 35W/inch³, allowing the power supply to exceed the 80 PLUS Platinum efficiency requirements, says the company. Featuring a 12V DC main output, it also provides optional standby outputs of 12, 5.0 or 3.3V DC output.
The hot-pluggable units are capable of N+1 redundancy and feature active current sharing (ORING FET) to connect up to eight in parallel.
Control and monitoring is via an I²C compatible PMBus interface and front panel LED status indicators. Over-voltage, over-current, 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 version is an AC input unit accommodating the full universal input range from 90 to 264V AC. A DC input model, D1U54-D-1500-12-HxxC, is also available in the same size.
The D1U54 series targets power architecture, and can be used with networking equipment and server and storage systems.
