Murata announces the latest addition to the D1U3CS series of front-end, high efficiency, 1U packaged power supplies from Murata Power Solutions. The new 1000VRMS isolated DC-input model to the D1U3CS Series can deliver a full 1600 Watt, 12 VDC output with a conversion efficiency as high as 93% at half load. The D1U3CS Series has a power density of 29 Watts per cubic inch. A 3.3Vdc, 20 Watt standby output is also provided.
The DC-input D1U3CS series is hot pluggable, and incorporates low-loss integral ORing Field Effect Transistors (FETs) on its main 12V output for fault-tolerant, redundant, and N+1 applications. With active single-wire current sharing, up to 8 supplies can be easily paralleled for very high current applications. This model has no minimum load requirement.
Digitally programmable, the unit is equipped with an I2C interface and supports the industry-standard PMBus™ communications protocol. The supplies incorporate fan cooling with automatic speed control and have an ambient operating temperature range of 0 to +50°C.
The D1U3CS series is comprehensively protected against overload and overvoltage conditions and delivers an MTBF of 395,000 hours. The power supply meets the rigorous EN55022-B and FCC part 15 Class B conducted emissions standards, and holds a full complement of international safety certifications including CE Mark and CSA.
Typical applications for the D1U3CS series include systems using distributed power architectures, such as computing, storage, networking, data centers and test and measurement systems.
