Murata extends D1U54 power supply series

Murata has announced the D1U54-D-1200 series of DC-input front end power supply modules. This 1000VRMS isolated power supply provides a 12Vdc output at 1200W, with a standby voltage at up to 20W.

The modules feature a power density of 28W/in3 and operate over an input voltage range of -40 to -72Vdc. The unit’s 54.5mm width and 39.8mm height minimises space inside to maximise user utility, and user rear panel area. This product series complements the AC-input D1U54P-W-1200 models and allows plug and play compatibility between products.

The hot swap enabled D1U54-D-1200 Series has integral MOSFET ORing in conjunction with active current sharing of the main output. These features are said to allow up to eight units to operate in parallel, providing the capability to drive larger loads or to build in N+N redundancy of supplies.

With a PMBus compliant digital interface, the supply can be monitored, managed and controlled using industry standard PMBus protocol commands. Safety features of the D1U54-D-1200 Series include over-voltage, over-current and over-temperature protection.

Model selection in the D1U54-D-1200 Series includes choice of a3.3Vdc or 5.0Vdc standby outputs as well as forward or reverse airflow.
