Hello Charlie, METI DENAN PSE Marking is mandatory for an external power supply.
* It may be hard finding a supply that is rated 5 V, 2 A but will completely cut off output current at 3 A. These small power supplies use cheap thermal overcurrent protection. In order to be able to provide 2 A at the higher ambient temperatures, the power supply will end up running fine at higher currents at lower ambient temperatures. * Small power supplies often have fixed plug blades. The North American version (with NEMA 1-15 pins) will cover North America, Japan and Taiwan. As such, it won't have Korean and Chinese approvals. You may find a version with replaceable plug blades. * There are dozens of vendors since your specifications aren't that far from what many cell phone and tablet vendors use. There are power supplies from Delta, LiteOn, Chicony Power, Phihong, Salcomp and many more. Most power supplies in this range have a USB output, but other output connections should be available. * Power supply manufacturers have become proficient at fitting a lot of marking on a small power supply. Some of the power supplies I use have regulatory marking on about 30% of the available surface area. For high volume products, the manufactures have fixed plug blades. This limits the markings to approvals for countries where the plug fits.

If so, does anyone know someone who makes an external wall wart PSU that meets the above, but also has PSE, KCC and CCC certification (and a large label :) ) Regards Charlie Charlie Blackham Sulis Consultants Ltd Tel: +44 (0)7946 624317 LinkedIn: uk.linkedin.com/in/charlieblackham/<http://uk.linkedin.com/in/charlieblackham/> Web: www.sulisconsultants.com<http://www.sulisconsultants.com/> Registered in England and Wales, number 05466247 - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
