We see from your search that you're looking for information on the term "UL1950",
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 Supply is space-efficient option for cPCI systems from
Murata Power Solutions, which we summarised at the time by saying "A new small form factor AC power supply delivers 200W of continuous output power for CompactPCI systems".
A few weeks before,
we featured the news release DC/DC convertor comes in a miniature package from
Texas Instruments (April 2001-March 2006): "A new 1W isolated, unregulated DC/DC convertor is ideal for motor control, programmable logic controller and distributed I/O module applications".
In September 2005, we covered the news from FCI
concerning its AirMax VS
- take a look at Connectors put more power on the backplane
which says: "The AirMax VS backplane connector system now includes power connectors to provide increased current-carrying capacity between the backplane and daughtercards in chassis systems".
Take a look also at the news release from Digital Displays, SAW touch screens boast superior display clarity,
as well as Power rack meets ETSI standards from Ideal Power,
and Modular supplies boast top power density from Excelsys Technologies.
