Has anyone heard of or used the Sinometer DC power supply RXN 1510D(or GWR 1510D)? These are Chinese and I have seen them on an electronics supply site (Canadian - A1 Electronics). I am thinking about obtaining one as a power supply for deplating in a sulfuric cell - but are they any good? Can't find any reviews on them.

I just converted an old PC power supply. There are plenty of How-To, step by step sites out there to help you along. If you're dealing with e-waste, you probably have easy access to power supplies. If you don't, let me know. I'll send you one. An hour later, and a couple dollars spent, you can have a great little unit that works fine. Of course, you can always spend more money. No harm in that if you have it. I don't. Well, I don't have much to spend on a fancy unit.
 
I keep hearing about everyone using converted PC power supplies. When I was first got interested, the first thing I thought of was a power supply for a lab. Something like this:
http://www.amazon.com/Sinometer-HY3005D-Variable-Linear-Supply/dp/B000E14F56
This one is more than I'd spend, but used things like this can be purchased for $50.
They are nice because you can set the V or A to whatever you want. Maybe play around with slightly difference settings to see what gives the best deposition.
0-10 V and 0-10 A would probably be a better range than the one pictured
 
Thank you for the suggestions. I've looked up the power supply conversion steps on ehow and at least someone else has heard of Sinometer. Still looking for any reviews on the Sinometer adjustable power supplies, if anyone has worked with them.

I've sure learned a lot through the forum and lasersteve's DVD's - this forum is a real piece of work. It's good to see so much cooperation and helpfulness.
 
My .02:

The Sinometer as you probably realize is a piece of "lab test" gear and without any particular personal experience with one, is probably a very decent piece of test gear. By the way, I would bet you that I could find half a dozen Chinese-manufactured power supplies that produce a remarkably identical-looking item, with the same sized meters with the same number of knobs, in exactly the same place, with the same shipping weight and current/voltage specs, etc; etc; my point being, the "Sinometer" brand name means essentially nothing. I would bet it IS reliable and a reasonably decent quality power supply. No insult to Chinese gear intended here. Plus, power supplies are not rocket science.

Now, you wish to use the item in a plating/deplating application. The question is: Is it a good fit?

It would probably work fine. But it would also be somewhat fragile in terms of being able or willing to withstand a splash of acid or two.
Upon exceeding its current capability (ampacity is another term) it will shut down immediately because that is what it is specifically designed to do. Should your application (eg; stripping cell or plating bath) require more current than it can supply before shutting down, you'll have to reduce the size of your cell or the thing will become utterly useless. It is designed to produce very, very clean, filtered and tightly regulated DC power, which is not something that electrolytic cells dont need. At all. Won't hurt.

Personally, I think I would lean more towards a cheaper, more rugged, don't-much-care-about-cleanliness-of-output, also considering the various price bands these things occur in. To wit: (I could not find the exact specs of your model number, for some reason) but such supplies are pretty cheap, like $89, for 2 amp-4 amp supplies. If that does it for you, then I consider $89 a relatively expendable amount of money, you want those nice meters and knobs, knock yourself out. But I think that even smallish cells can generate surge currents in the 6-8-10 amp range and I think you will see that such a bench supply that can handle that without shutting down will be more in the $300+ range.

And it also depends if you are just starting out with the idea that you'd like to try this stuff or if you're an established business and blah blah blah. It also depends if you can solder a line cord to something or make the mods needed to convert a FREE power supply from a dead PC. That way, with the $89 you save on the power supply, you can buy a decent quality meter or something else.

I'd use one of these: http://www.ebay.com/itm/LAMBDA-LOS-X-5-OPEN-FRAME-POWER-SUPPLY-5-VDC-9-AMPS-NEW-/230656387805?pt=LH_DefaultDomain_0&hash=item35b4312add $15.

Or if I wanted the voltmeter on the unit, a battery charger that already has the clips on it and can work as a battery charger.

I think I am saying that while the precision of your listed supply is a nice thing, it is an unneeded frill, and the danger is that if that supply cannot supply your surge currents or shuts down all the time, it will be a thorough waste of money no matter how much it cost.
 
Well there is a lot of food for thought in that post elements. You've made many really helpful points. I think that pretty much covers the field - so I can make myself an inexpensive unit to do the job. Thanks. It causes me pain to realize how many pc power supplies I have let the scrap dealer have (for the price of the copper anyway). Anyway, shouldn't be difficult to get hold of another one - they're everywhere. Maybe you've helped out some other newbie who reads the post too.
