We see from your search that you're looking for information on the term "CISPR22",
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 Convertors are tough enough for industrial use from
Schaefer, which we summarised at the time by saying "Rugged 70-150W DC/DC convertors are ideal for a variety of applications, including process control, instrumentation and industrial installations".
Several months prior to that,
we featured the news release Compact filter cleans up convertor inputs from
Tyco Electronics Power Systems: "A new DC/DC convertor input filter module provides a space efficient and cost effective solution to meet electromagnetic interference limits mandated by various international agencies".
In April 2004, we covered the news from Murata Power Solutions
concerning its SLC100
- take a look at Low-voltage convertors deliver up to 40A
which says: "A new series of standard open-frame quarter-brick convertors is capable of delivering up to 40A at voltages as low as 1.0V DC".
Take a look also at the news release from Emerson Network Power - Embedded Power, Hot-swappable power modules offer rugged operation,
as well as It's cool to supply 120W without a fan from XP Power,
and Eighth-brick family gains 1.2V output from Murata Power Solutions.
