2.2 DC power supply for server rooms in the data centre3.5 Fault current acquisition4 Conclusioni Further information:When an arc is generated, fault currents may possibly be attenuated very much, so that these fault currents may be lower than the operating currents in case of a non-self-ex-tinguishing arc and hence lower than the trip currents of protective devices. In contrast to AC power supply, it is therefore not suficient for DC power supply design to consid...See more on assets.new.siemens TI [PDF]
Power Solution Options for Data Center Applications
In this white paper, I will compare the different options and their advantages and disadvantages. One major issue to consider when designing a power supply for server and switch applications is heat.
