We see from your search that you're looking for information on the term "EN60950",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release AC front end keeps it clean on the powerline from
Ultimate Renaissance, which we summarised at the time by saying "Universal-input power module presents a near unity power factor to the incoming powerline, and generates a typical output of 393V DC".
A couple of weeks before,
we featured the news release Eighth-brick convertors power through the heat from
FDK Corp: "Convertors provide 30A output at regulated voltages of 3.3 to 1.2V with little or no derating at elevated temperatures".
In October 2007, we covered the news from Schroff UK
concerning its Power System 1400
- take a look at Rack power system includes UPS option
which says: "System provides a total of 21 individually fused 56V DC outputs and delivers a maximum output power of 1400W".
Take a look also at the news release from Ohmite, Resistors handle high currents,
as well as Small module corrects power factors from Emerson Network Power Embedded Computing,
and Compact power supply provides quiet operation from Excelsys Technologies.
