Hard drive enclosure power supply

  • Thread starter Thread starter Harvy

So, if its 12.95 for the PSU and the same for an enclosure with PSU who
the hell buy these things (in reality no one should be), then that
means the companies must realise hmmmmmm why is no one buying these? oh
its because they are cheaper elsewhere and come with more circuitry(the
enclosure). Also I've had 2 hard drive enclosures so far and they have
both come with the same PSU (but different labels) and the same tip and
voltage configurations, I have also bought one for a friend which had
the same configuration. All these enclosures were from different
companies and bought at different places (computer fair, ebay and
Japan). Yet all had the same PSU, this means some one is selling these
en-mass somewhere.....

Only to the enclosure manufacturers, not necessarily to the public.

The problem with these adapters is that they are usually a custom job,
i.e. produced spefifically for the specific enclosure. ''Normal''
industrial brick-type PSUs usually only deliver one voltage output
and are much more expensive due to significantly higher quality
standards. (As a side-effect, they usually do not ''blow''...)

They are not. At least not as stock items.



Are you blind? It clearly says "Specifications/Features: Removed from
New Equip". This is not a stock item or from normal production. This
is from overproduction or a failed businesses inventory. That is why
it is so cheap.

Brand new ones are stock items but about twice as expensive from
www.jameco.com or MCM, making them about the same cost as a whole
external drive enclosure with PSU.

You said these bricks weren't stock items. They are, and they're
common.

I said that single output onse are stock itsms, but dual output
nes are not. Please give me a reference if they are. I would
like to buy some too.

Why would they have to be custom units for common +5V and +12V and a
mini-DIN plug? Also what's wrong with surplus for something as generic
as this, especially when there are no special size constraints that
have to be met? Nonetheless, here are some part and stock nos:

MeanWell # P50A13D-R1BU, Jameco stock #221701CM
Ault #SW300, Jameco # 190650CM

How about brands like Asian Power Devices, Unifive, Delta, and Power
One?

Nice, then these things will now hopefully start to appear
in with electronics parts distributors soon. (It is not really
helpful if you can buy 1000 pices from the manufacturer....)

At the moment you still cannot buy them, e.g., with Distrelec or
Farnell. And I would trust one from, e.g., Traco a lot more that
from some of the brands you name.

What if you have an external drive enclosure containing a power supply
that isn't safety certified and looks like this:

http://static.flickr.com/51/128289379_5034f765c4.jpg ?

The heatsink in the lower left, under all the wires, holds a high
voltage transistor and presses against the USB controller normally
mounted just above it, separated by just a thin sheet of plastic. I
removed this PSU and replaced it with an external one that was UL
approved. Fortunately, I didn't have to pay for the PSU because IOmega
misdiagnosed the problem I was having with their external drive and
sent me a replacement PSU.

Urgh! This one must be the most dangerous design I have seen
so far. This is not UL/GS/VDE certified, because it would never
pass.

Wise decision.

And this has what exactly to do with Joe Public buying an external brick power
supply through an industrial distributor or a professional powersupply maker?
Click to expand...

It's a warning that Joe Public shouldn't buy AC-powered stuff that
isn't approved by a safety organization like UL, CSA, or TUV (but not
CE, which doesn't seem to require actual samples to be submitted for
testing. The PSU shown above was claimed to be CE approved). And, as
has been mentioned, some people who need a brick PSU for an external
hard drive enclosure find that it's cheaper to buy a whole new
enclosure, and I wanted to warn that some of those enclosures can be
dangerous.
 
Hi, Well I have finally got my (other hard drive) now when I plug it
in it works fine but when I put the P/s2 cable into the hard drive it
didn't work. Upon further checking I compared the diagrams of the
voltages assigned to the P/S2 type pin and realised they were different
the ground pins were swapped with the 5V pins. Any ideas on how to swap
them over? The most obvious is to chop the cable and then swap the
wires inside the sheathing then tape it back up, but is there any other
way?

The proper way is to solder on a new connector.

Not a trivial exercise if you are just learning to solder tho.

Don't bother. If you were actually careless enough to try this with
the electronics, then you fried them.

I have eventually wired it up correctly and now the power supply and
hard drive are fine. But yet again another problem has popped up. My
hard drive is one of those media player types which has a remote
bundled with it so you can use it as a stand-alone device on you tv via
A/V cables. When I connect it up to the TV, the menu comes up (so the
firmware is working) but it states there is no media. When I plug it
into my Pc it is fine and I have even tried different hard drives. Any
response?
PS> the web-site is http://www.thanko.jp/35mediaplayer/index.html but
it needs translating from japanese.

Wall-warts aren't common as stock items? You might want to visit a Radio

Wall-Warts with 12V @ >= 1.5A and 5V @ >= 1.5A are not common.

Instructions:
1. read
2. understand
3. think
4. if sure 1...3 were sucessful: criticise

Well, buy him a ticket to the States then.
Tandy/ Radio Shack left Europe a long long time ago.
