Murata squeezes 650W power supply in 1U

Murata’s latest standard 1U format power supply is rated to 650W, but is still 228.6mm (9-inches) in length.



The D1U54P-650-12-HBxC series has a specified power density of 21.4W per cubic inch. It provides a single 12Vdc primary supply and a standby 12Vdc, 2A output.

The units are designed to be hot pluggable and to be capable of N+1 redundancy. There is also an active current sharing (ORING FET) permitting connecting up to a maximum of eight units 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 264Vac.

A DC input model, D1U54-D-650 is also available in same size.
