Power Supply goes up in flames
« on: June 13, 2017, 08:23:03 am »
Here's an interesting link from Big Clive:



It seems that someone bought an inexpensive bench power supply, hooked it up to a peltier device, and left the apartment.  Choas and flames ensued.

Scary thing is, I think I was going to buy one of those, before I bought the Korad instead.  And the Korad isn't a high end name brand supply, but at least they hit normal manufacturing standards.  Their stuff doesn't catch fire.  Mostly.

Best, Charlie

It's ok, an easy mistake to make.

I sometimes worry about the potential for safety risks, with all the cheap stuff imported from China. You can get quality/safe stuff made in China (usually controlled/regulated by Western companies, who look after the Chinese factories, to keep them good quality and safe).

But when it comes directly from (relatively) unbranded companies in China, and they have been 100% left to their own devices, to design/build it how they want. Combined with a super cheap price including delivery, and being sold on (typically) ebay. It is often a recipe for disaster.

I'm surprised there aren't a lot more incidents like that, and that people get injured or worse and hence the governments are forced to take action.

BigCliveDotCom demonstrates a lot of highly unsafe items, coming (usually) directly from China, via ebay. They either catch on fire, batteries smoke/flame badly or potentially electrocute the unsuspecting user, or maybe hide some other nasties.

Wow, that's scary.  Been reading up somewhat on power electronics and want to get into building PSUs, possibly some high power rectifier and inverters for my server room, and possibly solar.  These would run 24/7.  I'd only do this once I've built smaller ones and feel comfortable though and have read up on proper testing procedures (I presume there are standards for that?) and tested them a lot.   How easy it is to mess up a design for something like this to happen?  I would not have figured that something electronic like a PSU would have enough flammable material to burn to this extent.   Like, that even melted the front casing and looks like it even got hot enough to warp the metal!  It almost looks like it was designed by ISIS. lol

It was designed to pass the 'brief' inspection at the end of some back alley assembly line  :phew:

After that, it's the buyer's baby (or BBQ)    :-[

Is it made by Ford? I was worried last week, parked and saw the vehicle in front was a Ford Kuga, which has been recalled because they have had quite a few catch fire while driving, and which also had the unfortunate issue of the doors failing locked when doing so, killing at least one person.

It's unfortunate that consumers are not told by commission whore Red Bull and ice tanked sales staff,

that most new purchases include free random BBQ capability !  :clap:

The customer merely supplies the prepared meatloaf   >:D

The decadent 'govs' are showing their true colors and grabbing all the   _under the table_   br!be cash they can fit in their coffers (and private piggy banks),   ;)

and **** the rabble serf that foolishly believe it's 'their/our Government'  :clap: :clap: :clap:

People need to read up on some history if they can give games, sports and silly 'lifestyle' distractions BS a break for 5 minutes (lol, no way)  and get a clue.   :horse: :horse:

There's a LOT of 'Towering Infernos' out there waiting to happen, either by crappy design or too close to airports,
as well as leaving BBQ capable PSUs left on unattended, to recharge a personal vibrator on the 60th floor...    :palm:

hmmm, I think I'll give electronics the Ebay treatment and run for politics or council instead,

"the pen is mightier than the differential probe" as they say...or something like that      ;D
