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

thank you very much for your clarification. my dear friend
if you have any question, you can contact me .
waiting for your new work

thank you for your support , about the input , in fact , it is easy to find switch power supply or second hand conmucation power supply, they are all cheap.
or you can use a battery to make a portable power supply.
I use DPS3005 to make a portable power supply.

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.

I know what you said . thank you for your support, I saw your order , it is on the way, you will get it soon
thank you

I updated the OP with more pictures of the completed unit.

waiting for your picture

Looks good and works as well. :slight_smile:

you can buy one to test

Thanks for the generous offer to test. :slight_smile:

sorry, we don’t provide free

Cool build. What a nifty tool. I almost missed your post stating that you updated the OP.

I have this one already.

Is yours much different to this? I know yours has the front panel which looks real nice.

+1!

This Portable Benchtop Power Supply is not my first attempt at this. 2 1/2 years ago I tried doing this with lesser modules and the result was less than satisfactory. Both of the supplies in this link have since gavin up the ghost. They were rated at up to 3A, but couldn’t even do 1 1/2 at certain combinations of input and output voltages.

Thanks guys for the comments.

Here is a question for RD Tech or anyone else that may know.

From the instruction manual concerning connections, we a warned that connecting the supply to the output will burn up the unit.

So it would seem that if this unit is used to charge a battery, and it has no supply voltage or it is not turned on, the battery we are trying to charge could back feed into the unit and burn it up.
Is that possible?

Hi friend
good question . in fact , this is just warning that connect the module with right way. in fact, you connect a switch power supply less than 50V with output , there is no problem. but why you connect power supply on output … right ? :smiling_imp:
about the batter, now all our version of DPS and DP power supply can charge the battery. but you can’t connect it reverse polarity , ok? it will really burnt module . because we all add a similar with diode circuit , it can prevent current flowing back. don’t worry
but if you connect the battery at output , and you power off , the module will consume power of battery
thank you , hope it is useful for you
