PINNED ZXD2400 Old + New 0-60V 0-50A Power Supply & Charger

[shirley_hkg]

Picture shows exactly what they come with now.

[Burgerman]

That should work great.

[shirley_hkg]

3mm pore size seems the biggest we can get.

[Burgerman]

Yes that should work.

THIS would be great. But backrupt me!

Good afternoon.
Shirley, I would like to buy a ZXD please. I think the best one for me will be the slightly smaller of the upright ones.
I will pm you.

[Burgerman]

There are 2 different smaller ones.

One has bigger screen and smaller fan. That I am getting.
Other type has smaller screen slightly. And a bigger normal fan. And probably a bit quieter.

[shirley_hkg]

They both have the same 8cm fan, only different front plate layouts .

[Burgerman]

Oh. Just LED placement different then to make space for bigger screen. Both 20mm shorter height.

[Burgerman]

The one I am expecting in december.

Front has:
XT90 and that can do full power @ 0-50A and 0-60V.
4mm banana type posts, 20 to 25Amps safely. More if you risk it! Mostly for bench electronis use.
80mm fan, status LEDs lower below screen, side vents for cooling air added.

Rear has:
AC connector.
2x 4mm SENSOR bananas for temperature monitor and voltage compensation - not essential but nice to have.
Custom: Anderson 50A connector.

Will make up a bunch of XT90 leads with XLR, Anderson, XT60, Croc Clips, a long XT 90 extension. Y adapter leads for charging several things at once, multi leads with several different ends, etc.

[ex-Gooserider]

Maybe not. Pore is bigger.

How about get rid of it ?

Bigger holes are good, but you don't want to get rid of the guard totally on the INPUT side of a fan as if you stick a finger in you are likely to get damaged - the leading edge of the blade hits first and is angled to pull you in.... I often get rid of grills on the OUTPUT side, as the flat of the blade is what would hit your finger, and it would push it out....

[shirley_hkg]

No. I wouldn't get rid of the mesh.

The encoder is in the centre, that allows no room for anything thicker than 2mm.

Just keep it this way.

[biscuit]

Now I've ordered this (actually, the lying-down version) from shirley-hkg as I really do need a 3-stage charger.

To celebrate ordering the new ZXD from Shirley, I put together my old ZXD. I was re-reading from page 1 of this thread and observed that I was getting too hung up about it - strewing tools all over the floor and dropping bits of ZXD are legitimate parts of the process.

So I fiddle-faddled with the millions of microscopic bolts and things until the old unit was assembled with only 2 nuts left over. (Four if you count me and my mother, who braved the workshop periodically to help me find minuscule bits of ZXD.) The ZXD nuts were meant to go in the darkest deepest innards of the machine to hold the SB50 and I did not enjoy assembling the case enough to do it all over again with the nuts in place, so the Anderson is rather umm. I did experiment with removing the handle and found the machine too heavy for me without it.

Now to wait! It is extravagant, but when the new one arrives I'll be able to figure out how to programme it for my gel batteries and see what the old one is now doing in comparison.

Is it some kind of humour ?

[Burgerman]

The laid down one isnt smaller.
Thats why I changed my mind to get the smaller upright one. More portable.

You think that those parts and screws are small?
You should try rebuilding a laptop or worse some of the hooby stuff I use!
ZXD parts are pretty big. The last one I built took me about an hour because I had to solder and add anderson etc that wasnt part of it. On a desk, on top of a white sheet so I can see all the parts.

The ZXD nuts were meant to go in the darkest deepest innards of the machine to hold the SB50 and I did not enjoy assembling the case enough to do it all over again with the nuts in place, so the Anderson is rather umm. I did experiment with removing the handle and found the machine too heavy for me without it.

I didnt use any nuts. I tapped the Anderson with a M4? thread from memory, and added a couple of countersunk allen screws from the outside.
Buying pre assembled is a new thing for me! And yes its easier!

[biscuit]

Shirley, you are a champion!
My older machine also came from you and it very soon suffered an accident while I was ill! So the only thing to do was to laugh at my misfortune and ask you to to sell me another one.

I figured none of the ZXDs are really portable enough for me. My power supplies are very lightweight, a couple of kilos. I'd choose one of them if travelling, I think.

Yup, that is why I don't do that stuff.

[Burgerman]

I am 65 in april. My eyes dont work. I have THREE sets of different dioptre glasses on my head at once, and have to swap repeatedly, lose tools, screws, etc for hours at a time, and have to repeatedly redo/rebuild when I see I got it wrong. Again... At the last moment.

Its frustrating. But thats how I learn. 65 years of fixing and modyfying everything from cars, bikes, chairs, houses, electrical everything and I never accept defeat, and I get better at this stuff over time. Practice makes you better.

I honestly can fix anything. If its possible I can fix or improve anything at all. Dont care how complex or fiddly. Its not always easy.

An expert s someone that has made every mistake.
A master is someone that has made every mistake many times.

Still too heavy for travelling.

Mine is <1kg / 24V~10A.
£23.

[Burgerman]

13.8 / 27.6V means OK for a couple of weeks. Will get a 90 to 95% charge in about 8 hours. 98% in about 16 hours. 100% in a day.
But ideally you want 14.1 / 28.2 V for overnight. 99% overnight, to 100 full in CC? x hours +/ 8 hours @ CV

But good enough for holls...

Heres what I would do if I were you. Yes I know I am not!
Aquire all the tools you need, decent quality and things like soldering irons, ifixit screwdriver/tool sets and sets of spare screws/wire/connectors/multimeters etc. I did this over time as I needed them. God knows how much gear I have ££££.
Same with bench, light, magnifying screen, magnetic dish or keeog screws, tweezers, side-cutters crimpers (not hair) etc.

Then TIME! and somewhere comfortable not the floor. And a white cloth surface on a table. So you can see screws etc...
Then take it apart, fit nuts, reassemble with care, a drop of oil or grease on threads, and take time! By the 5th go it will be perfect and you will have learned lots! For when your laptop or hair-crimper or phone dies.

[biscuit]

Truly I do not know where you get the patience!

[biscuit]

I discover that I am not actually too old to learn. And abilities I thought had atrophied were in fact merely having some down-time. On the other hand, the brain fog is a real pea-souper at present.

My soldering iron is a £15 one from Amazon. I didn't want to spend more because I can't solder. I dropped it on the carpet last year by knocking over the airy little holder that came with it. Miraculously it missed its mains cable.

A bad workman blames his tools, but maybe in this case a £50 station with a heavy base is a reasonable investment.

[Burgerman]

Definitely! An iron MUST be thermostatic . At least if its any use!

[biscuit]

Mine has an encouraging little temperature dial on the handle. Accuracy? Idk.

The Hakko ones I see on Amazon, well same with the cheaper ones as well, their fatal flaw is that top heavy iron holder. I need one with a heavy base that I can't knock over.

Next month...

[Burgerman]

Think laterally.

I have a hakko. Very good but not cheap.
https://hakko.co.uk/product/fx-888d-dig ... on-silver/
Mines old so blue yellow. And much cheaper than this! Same though.

Have a workbench with a bit of velcro on it ready to accept your irons base/stand.

[Burgerman]

Ignore the 2 chargers, batteries, white crane handle, and the van charger sat at 13.2 on the wall... And spirit level etc.

Heres what you NEED to solder a lot of different things neatly and easily:

1. a table or bench... Grey thing!
2. a good thermostatic powerful compact iron that responds fast. So it doesent cool in contact with a lump of metal, and doesent overheat and turn black and burn the flux off... Blue/Yellow thing. On its right is the actual iron in its stand. That has some brass cleaning "wool" thats essential to keep it tinned and shiny.
3. 2 huge blocks of Blue-Tack, dirty and abused and covered in flux etc to hold wires, connectors.
4. In front of blue stuff, tin of flux, a rosin very mildly acidic flux paste. This stuff is the secret to soldering. Looks like earwax. But dont know if that would work. Dont try it.
5. plastic tupperware container has a "turbo" lighter. Thats essential for bigger connectors or things that the iron isnt man enough to do, e.g. XT90, Anderson....
6. plastic tupperware container again... ACID plumbers flux for tinning or soldering old stubborn oxydised stuff. Old wires. That stuff is horrid on your skin.
7. plastic tupperware thing again. Different types and THICKNESS solders. Always use lead/tin (60/40) cored on electronics stuff.
8. Small tin of iron tinning stuff. Make it easy. to fixand re-tin the tip.

You MUST have a clean fluxed joint in order to properly solder anything. Unless its a tiny bit of electronics the cored solder alone is not adequate.
You MUST have a shiny tinned clean iron. To keep it that way you have to keep cleaning the tip, dipping in the flux, and retinning with solder. And once the joint is soldered, turn the iron off after dipping in flux/solder ready for tomorrow!

Soldering is simple. CLEAN, unless fresh clean parts, cable. Flux, and heat JOINT quickly and not the solder. The solder can be used to help transfer the heat, and when joint is hot enough it will run and do the joint for you all smooth and shiny in a second. STOP.

A joint shouldnt take more than a couple of seconds or you are doing it wrong. If it does you will have to re clean it and start again as once too hot it oxydises and garantees no soldering...

[shirley_hkg]

Sorry for the long wait.

[Burgerman]

No anderson on top. Ugly! Ruins the nice design.

And large screen on mine? Eyes...
https://www.wheelchairdriver.com/board/ ... &mode=view

If anderson has to be external or on top, dont fit one.
I already have 2 ZXD's with andersons fitted.
So not needed.

[Raro]

Yes, it looks ugly with the exterior Anderson, I guess there won't be a zxd with Spanish language, right Shirley?

[shirley_hkg]

youtu.be/XvLakOQdbTI

It won't a zxd with Spanish language, right Shirley?

New ZXD is bluetooth upgradeable, and is still developing, though only English and Chinese are available for the time being.

Anderson SB50 on the outside is a bespoke set.

It's not everyone's cup of tea.
