PRODUCT OVERVIEW  
The D1U3CS-W-850-12-HxxC series are 80 PLUS Gold efficiency 850 watt, power factor corrected front  
end supplies with a 12V main output and a 3.3V (20W) standby. They have active current sharing and up to  
4 supplies may be operated in parallel. The supplies may be hot plugged, they recover from overtempera-  
ture faults, and have logic and PMBus status signals. Their low profile 1U package and >15W/cubic inch  
power density make them ideal for delivering reliable, efficient power to servers, workstations, storage  
systems and other 12V distributed power systems.

For 5vSB, contact Murata Sales for availablity.  
Ripple and noise are measured with 0.1 μF of ceramic capacitance and 10 μF of tantalum capacitance on each of the power supply  
outputs. A short coaxial cable with 50Ω scope termination is used.
