Portable Bench Top power supply using the DPS5015 - FINISHED, for now

meh. $36 for cables and boards and then you need to buy a SMPS to connect to it too? No thanks. It’s not portable at all with all that raw PCB and cables dangling. And building a box for it all would be time consuming and huge. I don’t have a use for it.

i can think of a few times this would have been handy.
beats the hell out of lugging my hp 0-60v 35a rackmount somewhere.

^ You didn’t build the required SMPS into it. And if you used a laptop power supply or similar you would not have the watts this thing is capable of. For $55 you can get a 30v 8A power supply on ebay that plugs into the wall and has a case. CC and CV.

As I said, I don’t have a use for it. But calling it ‘quality’ or ‘powerful’ because you can ADD a quality/powerful power supply seems misguided.

We’re all ears. Please tell us why gauss163 declares it powerful and quality.

You might want to do some research on how a (good quality) hobby charger adjust the voltage and current when charging a lithium battery.
It is not “just send it x voltage and y current and wait until full”

My view is neither negative or positive. I have no excitement for it though.
The review link is not working.

If the final product is useful to him, then the cost is justified.
If it would not be useful to you then you are right, it would not be worth it to you

ImA4Wheelr knows me all too well. He zeroed in on that topic when he posted this:

He realizes that this build will cost me nothing other than the price of the DPS5015. The case is from an old battery charger and the power source, the yard tool battery, I already had and have other uses for it.

He knows that with all the stuff I am constantly buying, for example, Home Depot Deal Alerts & Discussion Thread I really gotta watch my spending. :wink:

we have new case now , old case , we don’t produce this now

you can’t change the display , there is some program to control it .

in fact , you can put the battery inside. it will be great, and you can add a charge circuit, you can see our work

When I first opened up this Ridgid dual bay charger and I saw this sweet power supply, it crossed my mind that I could possibly use it as is and connect 2 of the DPS5015’s. I did mention that I intended to check out that power supply, and while I am waiting for my shipment, I will do just that. I will post voltages and current capacities later.

Perhaps what I could do is use one half of the dual power supply and have both a plug in Bench supply AND a portable one.
I think it would be as simple as a DPDT switch on the input of the DPS5015 to make it work.

Of course it would all have to fit in the case and all.

I do know this, starting right now I will be scrounging around for another one of these Ridgid chargers.

you buy it from our alixpress store ? what ’s the order number ?

I hope you didn’t misunderstand my last post.

What I was saying was that after I finish my portable supply using the DPS5015, I may order 2 more DPS5015’s to build another plug in supply if I can find another old Ridgid battery charger.
