Murata’s DC-input front end power supply
Murata has announced DC-input front end power supply modules with a 1,000VRMS isolated power supply providing a 12Vdc output at 1,200W with a standby voltage at up to 20W.
With a power density of 28W per cubic inch, 54.5mm (2.15-inch) width and 1U height, it is suitable for 1U and 2U applications in servers, storage equipment, data centers, and telecommunications network equipment, says the company.
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.
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 new series include over-voltage, over-current and over-temperature protection.
Model selection includes choice of 3.3Vdc or 5.0Vdc standby outputs as well as forward or reverse airflow.
