Murata has 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 O-Ring Field Effect Transistors (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 high typical conversion efficiency of 92% at half full load.
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.
With active single-wire current sharing, multiple supplies can be easily paralleled for very high current applications. The supplies incorporate fan cooling with automatic speed control and have an ambient operating temperature range of 0 to +50°C. It is comprehensively protected against overload and overvoltage conditions and delivers a mean time between failures (MTBF) of more than 500,000 hours. The power supply meets the rigorous EN55022-B and FCC part 15 Class B conducted and radiated emissions standards, and holds a full complement of international safety certifications including CE Mark, CSA, and TUV.
