If the power supply supports both 115 V and 230 V nominal voltage, does it automatically select between them, or is there a manual switch?
Frequency: Acceptable frequency of input power (50 Hz, 60 Hz, or 50 and 60 Hz). Alternately, a range of acceptable frequencies (for example, 48-62 Hz). Most power supplies can handle both nominal 50 Hz and 60 Hz input. Power Factor: The power factor that the power supply presents as a load to the utility power line. Normal power supplies will be in the 60% to 70% range (0.6 to 0.7). Power-factor-corrected supplies will have a number like “0.99”. Sometimes, the spec will just say “power factor corrected”. http://www.pcguide.com/ref/power/sup/spec.htm Output Specifications The most important specifications that you will find listed for most power supplies are probably those that relate to its output signals. The reason for this is pretty obvious: providing the output voltages are what the power supply exists to do. Carefully check over all the output specifications for any power supply that you are considering using. Some manufacturers will list separately the values for each of the spec
