Dangerous manufactureing..

Certainly grounds for a negative feedback rating on eBay. Curious... the guy didn't elaborate on what he did after he ran all the tests.

What are the penalties for forging a CE or UL logo nowadays, anyway?

Have you alerted 'the authorities' ?

It's this kind of stuff that CE was meant to stop. However the politicians didn't apparently realise that unscrupulous ( Chinese etc ) companies would simply lie.

Personally I'd probably give the seller a chance to refund the buyer's money and withdraw all other auctions before summarily giving him a negative -- there's a non-negligible chance he doesn't know he's selling counterfeit goods.

There's a good chance the real manufacturer is in China somewhere, so going after them is probably impossible.

Well maybe the seller was fooled to. You can neg one seller. But you hardly neg 100s of chinese fakes. I just wanted to make people really aware of not only malfunctioning but outright dangerous equipment these kind of business will do.

In essense scrutinize equipment construction.

Import ban?, until they change name? :)

CE is joke. I don't trust it. Semko and the alike are the only ones I would consider.

hardly

would

That assumes that US Customw will have the time, budget and expertise to inspect the documents when the parts are imported.

What name? That product doesn't have a manufacturer's name on it. There are large companies (over 1,000 employees) such as Xi*m*n H*n*** who have done this in the recent past.

At least there's generally a file number you can check out. I've seen UL and CSA markings fraudulently applied more to production quantities of parts more than once. I also have observed special inspection stickers being moved from one item to another.. ha.

This CE thing needs some kind of similar bureaucracy probably. Allow the manufacturer (make them a few tens of dollars if necessary) to electronically file a statement of compliance, SIGNED by SOMEONE with signing authority at the company) with full company identification and tax numbers and give them a file number in return. Perhaps verify the information (that would cost a bit of money, but nothing compared to lab testing. Store the file number and make part of the information publicly accessible. Indicate whether self-test or accredited lab did the testing, and references to the latter.

No, that's left up to the importers, customers and competitors.

That adaptor had plenty of forged marks. I don't see why it's any more difficult to put Semko on there too.

Graham

It isn't but, Semko is at least serious if it's there for real ;) In the end anything can be printed on. Other methods have to be applied I guess..

(I sure wish Peter Brevik woulldn't use that ridiculously long username with no spaces in it.)

"The guy" posts here from time to time. It's Mike Harrison's site.

I chucked it in my box of assorted PSUs and got on with some real work...... (Someone from Dell's Legal dept. did subsequently ask me where I got it from....)

"I recently picked up an AC adapter for a Dell laptop I bought on Ebay"

You bought the laptop on E-Bay. Where did you by the AC adapter?

Useful info that is not retrievable directly from the web-page info is

- wording of the caution label

Is this something like: 'designed for use Dell Inspiron 8500, Inspiron

When a product is designed specifically for use in a product, then testing will use that information to establish 'normal' rises, EMC compliance and other issues.

Any other testing is considered to be under the category of single-fault abormals, for which test limits are more relaxed.

This is not a pretty component, but there's no specific info here to suggest either misleading labelling or any malfunction or unsafe condition present in its intended end-use.

Misuse is abuse.

If adding weight to a component gives customer satisfaction, then it's a fairly cheap feature to provide - I've see it often in consumer products, particularly those sold over the counter where they can be 'weighed' against competition.

The case shouldn't be > 40C above ambient either btw.

Graham

The main concern here is intended use.

None of the products this was designed for consumes the combination of current and voltage being applied in this guy's testing.

As a single-fault abnormal, spot temperature limits approach and may exceed the actual listed ratings of the materials, depending on what location and component is being examined. This includes external surface temperature limits, which the OP hasn't actually recorded.

I'd rather shoot myself than stick this kind of thing into production, but safety approval agencies have only the written standards to go by, and there's no indication here that a specific line of a specific safety standard is being breached.

I scooted around the internet, chasing down the Dell PA-10,part numbers 9T215, 7W104, model numbers AD-90195D, NADP-90KB and the like, and can see nothing about his unit that suggests that its anything more or less than the normal Dell product.

The most that I can say, from casual reading, is that it appears that a thermal limiting method expected of this model is pretty slow at kicking in, in the OP's DUT. It wouldn't surprise me if this protection didn't normally result in a continous, regulated temperature limit that was below single-fault limits, but not below normal limits.

This guy is simply demonstrating his ignorance of the standards in question, his distaste of low cost off-shore electronics and his ability to mis-apply some pretty expensive test equipment.

It might influence some pointy head at Dell to reconsider product quality audits if his page was more easily Googled in reference to the model number and the Dell brand name. However, with only a 90 day warranty and no actual fires recorded, to date, some other pointy head would probably be able to calm him down pretty quickly.

This doesn't even really rate a 'buyer beware' warning.

from....)

Nice! At least they followed up.

"Is it heavy?" "Yes." "Then it's expensive. Put it back."

;-)

I once used some ballast in a little project box just so it wouldn't slide around the table when I flipped a switch.

BTW, if you need some dead weight, I can get chunks of steel in about any size or shape for free; all I have to do is steal it out of the scrap bin. ;-)

Cheers! Rich

We made out benchtop delay generator out of steel so it wouldn't slide away when you pushed the buttons.

John

You *steel* the steal?

Yes, since it's a risky operation, I have to steel myself to steal the steel, and then steal away in the night. ;-)

Don't tell my you STEEL don't get it?
