Would this be applicable to UPS? Another exclusion is a supply which powers the charger of a detachable battery pack. The UPS would also supply power to the final product even with the battery removed. I would think the UPS would need to comply as well.

Section 301 which addresses external single output power supplies does not identify specific categories of products. The only exception that I found was for spares produced after 2008. Effectivity applies to date of manufacture of the power supplies. Interesting point, does it apply to ps manufacturers or End Use products? My take would be End Use, just like having the required safety mark. The enforcer (?) would come after the guy who placed it on the market...just my opinion. Policed? Don't know, but curious...

When must we comply to this requirement? Is this requirement for all products in all applications? How about Industrial or laboratory products? Is this a requirement for the power supply manufacturers or the End Use product provider? How will this be policed?

There is a tab for ac-ac supplies. The list is much shorter than the ac-dc tab, and the highest nameplate power rating is 36W.

By the way, I forgot to mention in my quest -- I was looking for ac-ac supplies. I found many ac-dc supplies... Don 561 912 6440 From: [email protected] [mailto:[email protected]] On Behalf Of Brian O'Connell Sent: Wednesday, April 09, 2008 11:07 AM To: [email protected] Subject: RE: Public Law 110-140 -- Title III Nothing I say represents the opinion of my employer or my cat, but my dog concurs. 1. My employer, and some other power supply mfrs, have had hi-eff component supplies on the market for years, but all the industries that we sell to (IT, medical, and instrument) just want it now, want the cost to be just above dirt, and yet want it super-simple (although some of our custom medical stuff has lots of bells and whistles). And almost no one wants a leading-edge, uber reliable, hi-eff power supply; so they remain expensive. You get what you pay for... 2. My employer, and several competitors, are developing small units to meet the 85% operating eff and the 0.5W off-line mode requirements. Most power supply mfrs were not, until recently, allowed to commit engineering resources to design units that conform to energy stds because, other than several non-federal governments, there was no clear indication that this legislative edict would be issued, and that it would effect a large enough scale that would 'force' the creation of a market for these units. That is, almost none of you wanted to buy hi-eff stuff until the Peoples Republic forced you too... I know that this does not answer the OP question. But, I think the compliance community needs to be aware of the basis of this messy situation. Also, for the next year or so, there will be confusion on energy compliance. There are still unanswered questions of the test metrics involved, and how to specify compliance. luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Umbdenstock, Don Sent: Wednesday, April 09, 2008 6:56 AM To: [email protected] Subject: Public Law 110-140 -- Title III Public Law 110-140, previously known as HR6 is now in effect. http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=110_con g_public_laws&docid=f:publ140.110.pdf Of significance is that external power supplies are now covered under federal law for standby and active mode efficiency (Title III Section 301). Efficiency level IV is required July of this year; the bill was signed into law in December, providing only a 6 month transition period. A number of power supply manufacturers for mid range supplies (50W) seem to be challenged to meet the standby limit. Would anyone care to identify vendors that they have had success with in providing level IV compliant mid range supplies?
