Murata has rolled out the D1U54-D-1200 series of DC-input front end power supply modules. The 1kVRMS isolated power supply provides a 12VDC output at 1.2kW, with a standby voltage at up to 20W. With a power density of 28W/in3, the slim 54.5mm width and 1U height format cuts space inside to maximise user utility, and user rear panel area.

This configuration is popular with 1U and 2U applications in servers, storage equipment, data centres and telecommunications network equipment.

The D1U54-D-1200 series DC-input models accommodate an operating input voltage range of -40Vdc to -72Vdc. This product series complements the AC-input D1U54P-W-1200 models and allows plug and play compatibility between products.

D1U54-D-1200 series

The hot swap enabled D1U54-D-1200 series has integral MOSFET ORing in conjunction with active current sharing of the main output. These features 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 5VDC standby outputs as well as forward or reverse airflow.
