Murata rolls hot-pluggable, 1.6kW, 12VDC power supply

Murata has introduced a 1kVRMS isolated DC-input model as the latest addition to the D1U3CS series of front-end, high efficiency, 1U packaged power supplies from Murata Power Solutions. Flaunting a power density of 29W per cubic inch, the device can deliver a full 1.6kW, 12VDC output with a conversion efficiency as high as 93 per cent at half load.

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 eight supplies can be easily paralleled for very high current applications. This model has no minimum load requirement. A 3.3VDC, 20W standby output is also provided.

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 zero 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 centres and test and measurement systems.
