Miniware MDP-XP Digital Power Supply tutorial

Tutorial for the new digital power supply from Miniware www.miniware.co...

[@nusdogg]

Just picked this up. I was able to set it up and use the graph, so thankyou for this awesome and easy to follow video!

[@ozzymandius666]

Oh, btw your reviews/tutorials are excellent.

[@alejandroalonsopuig]

Thank you!

Ooh new miniware products to play with! I can't resist toys like these to add to my collection, i already have the oscilloscope ds213 and soldering iron ts80 and screwdriver es121. I got to admit their products are very appealing and compact... but need to consider is it really practical for my needs when I can just use a normal 'boring' bench power supply. The oscilloscope and soldering iron were very practical and superb to use, but the screwdriver really was a gimmick for me i could not justify spending that much money for. These are boys toys that we cannot live without ;) lol! Again great and concise review, I like your style of thorough explanation!

I have es120 and ts100. Im planning to buy this power supply and the ds213 oscilloscope. I dont really need any of these, but these are so well made that i just want to play with them :D.

[@markgreco1962]

Gnome child agree!!

[@markgreco1962]

anyone see the power supply unit sold alone??? MDP-P905 cant find it anywhere

[@amciaapple1654]

Yes, it is on aliexpress.com when you search for "MDP-P905". The cheapest one I saw for $125

[@markgreco1962]

Amcia Apple One also just showed up on Amazon USA

Im not sure Im understanding this exactly but my graph only shows 30V and 5A no matter what I have the output set to so powering a low current device doesnt really graph anything because the range is so large. Does anyone know what Im doing wrong?

[@alejandroalonsopuig]

Yeah, in my case is the same. The graph has fixed Y axis (at least in my firmware version), so for me is not so useful for graphical current measurement. In fact I use the unit without the screen as it is not needed for the power functionality and thus I have a poquet size quite nice power supply.

[@marioalday5966]

Is there any way to power off the system? I mean, without removing the power cable.

[@alejandroalonsopuig]

You could stop the output, but the unit will still be on (although without any power output).

[@PizzaHandhelds]

hold set and menu for a few seconds

[@brainkod]

Where are you connecting that USB-C cable? My USB-C wall plug does not cooperate with my MDP-P905 and I have to use the barrel jack instead :/

[@alejandroalonsopuig]

In my case it works well. I used a Samsung usb-c unit from my mobile phone. Contact the distributor. They may tell you more. Good luck

[@brainkod]

@@alejandroalonsopuig Can you mention the model? I would like to look up the specs for yours and see if I can find a matching one.

[@alejandroalonsopuig]

@@brainkod I tested it today and it works well with any phone charger, even low current ones with no problem. I mean the unit switch could switch on. Obviosly if the charger gives you low current, the unit will give only low current to any load, but it works

[@brainkod]

@@alejandroalonsopuig Right, the reason why I asked for more specific specs is because my MacBook 13" 2018, 29W USB-C charger does not cut it. The unit does not even power up when I connect it whereas the barrel jack at 12V works fine (as in just powering up the MDP).

[@alejandroalonsopuig]

@@brainkod It is weird. I have the same Macbook pro. I have just now tested connecting the unit to one usb port, then pushed RUN/LOCK in the unit and it switch on perfectly. I am sorry to hear that the USB port doesn't work in your unit, because I think this is so convenient to have such small unit powered by usb for low current applications on the go. For example I can get a 24v source for PLCs or other devices just from a USB 5v port. I only use the barrell option for more current demanding applications.

[@AJRestoration]

It's a nice toy to have, but all I see is a little paperweight. For the €229,95 or $199 price tag, I think we can just buy a normal lab bench power supply.

[@techdoc.repair]

what's the cost on this bad boy?

[@nusdogg]

I paid 275.00ish shipped from Amazon for both the MDP-P905 Power Supply and MDP-M01 graph screen.

[@Ender_Wiggin]

Is this boost or buck

[@alejandroalonsopuig]

Don't know really

[@Ender_Wiggin]

@@alejandroalonsopuig does it depend on the QC3.0 standard to make the different voltages?

[@alejandroalonsopuig]

@@Ender_Wiggin voltage source could come from the usb connector or from any other power supply up to 30v via a different connector

[@Ender_Wiggin]

@@alejandroalonsopuig Would it still be adjustable to 30V with a 5-volt source that is not QC3? i have only seen people use QC3 stuff. The spec on the website does not tell me whether or not I can get 30v out with 12 volts in.

[@alejandroalonsopuig]

@@Ender_Wiggin Yes, you can. In fact this is something I also questioned and tested. I got 30v from 5v input, but obviously the current you could get is much lower than the one your power source supply

[@HAKOoooo]

OKEY!!!

[@josverstraten4133]

Read an extensive test about the MDP-P905: chinese-electronics-products-tested.blogspot.com/p/mdp-p905-digital-power-supply-tested.html

[@ozzymandius666]

It has a 90 watt max, no?

[@alejandroalonsopuig]

Yes, specifications say so. I didn't test the limits, but looks nice from my first tests
