Arrival: Cheap Chinese bench power supply

Ever since I found this online Chinese electronics and hobby outlet, I've been giving the credit-card a real workout.

Today I received the cheap bench power supply I ordered from China. Despite being beaten up in the post, it works just fine and will come in very useful in the workshop.

What will I use it for?

Well lots of things. Mostly, it will power the various DIY projects I've been working on but because it has current-limiting, you could even use instead of a 4-button charger it to charge your lipos -- but I don't recommend it.

For under $65 it was pretty good value for money.

I purchased this from http://www.goodluckbuy.com

RCModelReviews has no affiliation with GoodLuckBuy but I bet you'll find lots of cool stuff there -- and, like so many Chinese online stores, they are all priced with free shipping.

Get your credit card out and enjoy!

Hey Bruce, Same PS for $30, see t o t o b a y . c o m search for PXN-1503D

[RCModelReviews]

@bingobongo17 Yeah... but that doesn't include shipping. Add the shipping cost and comes to USD$75 -- a bit more expensive than GoodLuckBuy's price!

Looked a the Goodluckbuy website and its interesting: the range of goods is mind-boggling but you'll need more than good luck to find the cheap power-supply which was subject of the video. I had NO LUCK even  after searching for the product code (shown at beginning of video).

By the way, Bruce I am big fan of you and your work but where do you find the time? You must be a workaholic!

@jof1953 Search for "BEST-1502DD" it's SKU 62729 $63.17 incl shipping.

If anyone's interested, I can do a "review" of my own hotwire power supply which I built for cutting foam wings. It's very simple but can operate a hotwire up to 1.5m in length and has variable current for setting the heat.

[RCModelReviews]

@godofarchitecture For good foam-cutting you might find that you need more than 2 amps of current.

Don't get excited. There is nothing special here.

@DjRaveKing mine is a "hitachi PPD5002" for anyone who cares. you can find plenty of them on ebay for like 10 dollars second-hand. the power is a lot cleaner than most high-amp supplies, and it doesn't catch fire because there's no plastic in/on it

[DjRaveKing]

@Reiuyi Yup . Quality wise they are definitely made better , because it's for a server .

Anyways , nice snatch , i found a small tape drive SMPS too if it matters .

[Reiuyi]

@DjRaveKing i got a server psu a while back and the quality is amazing, it's not even made in china (though the components probably are).. you just can't compare them to regular psus you buy at your local store for $50, they're amazing for 12v/5v hobby projects

[DjRaveKing]

@droktane Well ... server PSU's are mostly no different from computer PSU's . Just tell me if they can be constant current adjustable or FULLY adjustable voltage .

[droktane]

@DjRaveKing That's true, but I guess I didn't mean the very-very cheapest computer power supply you could find.. mean some are obvious junk with 20ga wires coming out of them (thick insulation makes them look normal), cases that look like they are made of thin tin. Basically you get what you pay for. But my point was often you can find and reuse an older computer or server PSU that is of a much better quality than this, and it costs nothing. Just add some banana jacks. We need actual tests.

[DjRaveKing]

@droktane Nope . The low end ones are missing inductors , capacitors and whatsoever . And PC Supplies aren't purer then these ones , heck , you could swap the 10mF with a 20mF !

[DjRaveKing]

Apparently , i have me eyes fixed on the 60V 5A RXN605D

Thanks for letting me know the site ! It's a HEAVEN .

( I actually had me mindfucked by the countless soldering stations there ... Just picked a standard 936 in the end ) Because i buy one more just for the sake of having two stations .

[droktane]

Highly recommend you re-purpose an old or new computer PSU, since they require much cleaner power, even the cheapest models will far surpass this. You can put banana jacks on it just like this, if you wish. This is not a very comprehensive review since you did not review the actual power that it puts out, either with a meter or scope. I would not trust it, you get what you pay for mate. :D See here for ATX to bench instructions: tinyurl(dot)com/ajc2d

@RCModelReviews I would love to see the details of your foam cutter, I would like to build one as well.
