Hi Doug, I have seen this recently on another cord connected power supply, like you use on a laptop, and I wondered about that too. I am speculating, but it may be that the product was approved before TUV had NRTL status i North America, thus an approval by an OSHA/SCC accredited third party was required to sell it in North America. It could also be that it was done for marketing reasons, in which case we know there is absolutely no logical reason why.

In 20 years, I've never seen this before but that's not saying much. Why would a mfr get a UL recognition approval for a commercial ITE style single phase 155-230vac computer style product but for that same product get the TUV "GS" mark? Mfr is a stateside company. Product to be used in restricted areas with trained personnel only. But, one that essentially anyone could buy. What's the advantage of getting such a mixed set of approvals? I would assume such a thing would normally get a Listing. Maybe turning the question around for our overseas friends - why would you get a GS mark for your product but only get UL recognition for an ITE computer product when it's normal to get a listing for such a product? And now I'm wondering if with such a device that there's some deviation within the testing as to cause the product to be GS accepted but not with a listing.
