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.
Recommended: 120W AC-DC Power in 2 X 3 Inches
The dc-input D1U3CS series is hot pluggable, and incorporates low-loss integral ORing 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 degrees C.
