We see from your search that you're looking for information on the term "EN55022",
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 High-efficiency power supplies keep costs down from
XP Power, which we summarised at the time by saying "XP Power's AEL AC/DC power supplies achieve a minimum efficiency of 85% and consume very low standby power, typically 0.3W".
A few weeks before,
we featured the news release DC/DC and AC/DC modules make rugged supplies from
Schaefer: "Robust design uses industrial grade components and provides a high-density space-saving system for applications in industries such as railway controls and communications".
In December 2007, we covered the news from PIV Technology
concerning its Glacial Power AS Series
- take a look at Universal switchers put more power on the desktop
which says: "Supplies are geared towards media centre, POS, DVR, LCD monitor, LCD TV and IT applications and feature power outputs of 120, 150 and 180W".
Take a look also at the news release from Lambda, Single-output supplies extend to 1500W,
as well as Power supply allows cooling options from XP Power,
and Supply family spans DC/DC, AC/DC and chargers from Schaefer.
