Murata today announced the addition of a 1300-Watt model to their D1U3CS series of front-end ac-dc power supplies from Murata Power Solutions. The D1U3CS 1300 series can deliver 1,300 Watts from the wide 108- to 264-Vac universal input, is hot pluggable, has no minimum load requirement, and incorporates low-loss integral ORing FETs on its main 12-V output, for fault-tolerant and N+1 redundant applications. With a power density of 23 Watts per cubic inch, the power supply can achieve a typical conversion efficiency of 92% at half load.

The D1U3CS-W-1300F has a primary 12-Vdc output and an optional auxiliary output of either 3.3-Vdc, or 5.0-Vdc for powering standby circuitry. Active power factor correction is used to minimize input harmonic current distortion and ensure compliance with the IEC61000-3-2 standard, with a power factor of 0.99 typical. It accepts the universally available IEC C14 ac input power connector. Digitally programmable, both models are equipped with an I²C interface and support the industry-standard PMBus™ communications protocol. Both also contain a memory device (EEPROM) that is pre-programmed with data about the unit.
Typical applications for the D1U3CS series include systems using distributed power architectures, such as computing, storage, networking, data center, and test and measurement systems. The Murata Power Solutions D1U3CS-W-1300F is available at the competitive price of $246 per unit in production quantities. Standard lead time is 12 weeks. Sample quantities are available now.
