Excellent DC power supply
352317
This is an excellent power supply useful for a variety of devices. I use mine to power an Arduino (an embedded processor board), and to power various DIY projects.

Just remember this delivers a range of voltage up to 12V. 12V can fry devices not made to withstand it. Therefore it's a really good idea to "turn it down" to 3V when you have unplugged it in case you or someone else picks it up and plugs it into a sensitive low-power device like a GPS. This warning is not a device fault, of course, but a feature which you could accidentally misuse.

It does everything it claims - and does it well - so 5 stars. I do wish it also supplied 3.3V (not just 3V) as 3.3V is a power requirement for some electronics. (But I knew this did not provide that voltage when I ordered it, no fault there. For low and specific power needs like that, I really just need a bench power supply).

Great LED power supply with 9-42V and constant current of 1.4A at the best price I've found even with the shipping charges. I use it a single LED Cree Xlamp that produces over 4500 lumens (more than six 60W light bulbs). Mean Well has a reputation of quality power supplies.

The 'Velleman PSSMV1USA 3-12Vdc Switching Power Supply' Seems to be of a good quality.  All the voltages check out to be accurate and the connection plugs fit together well.

This is a really nice power supply. Heavy-duty aluminum case. Mounting tabs on either end with three bolt holes each. I'm using this to drive about 6 meters of 5050 (60LED/meter) strip for a 40" sign backlight.

I am very happy with this power supply.  It's clean.  I use it to charge radios that do not drop to a trickle when they are done.  It's just exactly what I need.

A great way to power a 20v DC computer directly from 12v DC. No need to inverter to AC and then power supply back to DC.

I bought three of these for Digitrax DCC power supply. All three perform very well with no complaints.

This is a good power supply for powering LEDs.  Im not sure why people keep saying in the reviews that they got lower wattage units.  Mine was 2.5A and 24V outputs which is 60W as stated in the ad and I put a strip that consumed 2A on this power supply and ran them for 12 hours straight without issue.  It did get a little warm but thats to be expected.

I think some people saying there's was wrong were looking at the lower input amperage by mistake (which is 1.5A).  Also people need to realize that while 2.5A is the listed output, thats a maximum and the loads applied should not be kept that high.

Have only had one day but has performed as it should.  The only star I would remove is because the output wiring guage is just barely large enough to handle 2.5A at 24V at the cable distance.

Do not hook these up to an inverter as one reviewer did.  Inverters will tend to pull far more current than these can provide over a sustained period.

I ORDERED THIS 12V/1.0 POWER SUPPLY TO REPLACE THE ONE THAT I HAD FOR A DIGITAL DEVICE THAT I USE.IT WORKS GREAT. I WOULD PURCHASE THIS PRODUCT AGAIN IF I NEEDED TO REPLACE ANOTHER ONE LIKE IT. I WOULD RECOMMEND OTHERS TO PURCHASE THE POWER SUPPLY. I RECEIVED THIS PRODUCT AT A DISCOUNT PRICE FOR MY HONEST REVIEW

Wow, such a great power supply. Very quiet, great power, easy to use.

This is a great power supply.  It has more than enough juice to run my machine with a 477k and a gtx780.  Im sure it will handle the addition of another video card with ease.  The only thing I dislike about it is the flat power cables that come with it.  They were harder to route though my PC than my last cables.

Excellent power supply for just about anything. I'm using several of these now to power amateur radios and they're working great. Highest load I have is a Yaesu FT-450D that pulls 22 amps at full load transmitting 100w and this power supply is handling it just fine. The fan can be noisy and have a whine at certain load levels but is not the same with every power supply.

Easily adjustable to 13.8-14.0v for use with radios, all you'll need is a DC volt meter to make the adjustment.

I like this power supply mainly because it stays so cool when in use and has the adjustable voltage for use with many devices.

It's the exact same power supply that my project debut carbon espirit dc came with. You should really put the voltage and amperage of this product in the description. 15V 0.8A

An EXCELLENT product - high power output for any device that needs it and yet a small, well built design.
Everything is self-contained, no extra A/C adapter or "brick" required and after using this device continuously with 4 devices at full charge mode, the power supply hub doesn't even get mildly warm!

I liked this so much, I ordered two additional units the next day.

This power supply works great for my Booster that I use now in the house. If your thinking that you would like to use your booster indoors and you only have a DC power supply then don't hesitate to try this one.

My old power supply died and I needed an upgrade in power 300w to this 460w supply. I have more USB devices and needed the extra power. This unit arrived in about 4 days. and was very easy to install. It has been working great for 4 months now. I am very pleased with my purchase.
