We see from your search that you're looking for information on the term "Safety approvals",
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".
Earlier in the week,
we featured the news release PoE injectors work with 1Gbit/s systems from
SL Power Electronics Corporation: "The Ault PW183 controls costs and saves time for OEMs because it eliminates the need for expensive electrical contractors, scheduling and compliance with local code standards".
In January 2008, we covered the news from Lambda
concerning its Power convertor suits varying loads
- take a look at Power convertor suits varying loads
which says: "Lambda's iAD12016A008V is particularly well-suited for powering a diverse range of loads in a variety of architectures, including distributed power".
Take a look also at the news release from Young Electronics Group, Power supplies are approved for medical uses,
as well as Power supplies work without cooling fans from Powersolve,
and Power injectors handle electricity and data from SL Power Electronics Corporation.
