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

[shirley_hkg]

What size is the small barrel connector on the front ? Or voltage sensing at the battery?

Voltage probe when using the 4-wires mode.

You run a calibration to let it measure resistance of the wires.

[Burgerman]

Thats what I suspected. On the PL8 which charges in a similar pulsewidth way, it measure voltage while "on" and while "off" continually. The charger then adjusts pulsewidth to ensure that the battery voltage is what you chose. At the battery. So does the same thing but in a different way down the 2 charge wires.

Result is basically the same.

I will make up a sense lead. What size is that barrel connector?

[shirley_hkg]

What size is that barrel connector?

Will be included, 5.5x2.1 though.

[Burgerman]

All good!

Will make a cable with croc clips on one end and a barrel connector on the other.
And another with it connected to the same charge anderson connector. So 4 wires at the XLR.
And another with it connected to the charge Anderson connector. So 4 wires at the Anderson.

[shirley_hkg]

I like the newest version. It's compact, and bigger 3.2" screen. (standard 2.4")

[shirley_hkg]

To give room for bigger screen, air intake opening is reduced.

What to compensate ? He open 2 intakes on its sides. A inflow spacer is added to ensure air flow.

Very nice and heartfelt design.

[Burgerman]

I dont like where the control knob is though. Everything else is good!

My NEW 3000 Watt ZXD Power Supply ships in a week. Thanks Shirley!
Rear has XT90 + Anderson 50, mainsAC.
Front has what you see here!

0-50A and 0-60V and 120 or 240V AC automatically.
2 stage or 3 stage charging, or bench power supply.

And very cheap considering the build quality ruggedness of electronics and the fact that its a better lead charger than all wheelchair chargers that I ever tested. And I tested many. AND a perfect PL8 or hobby charger power supply.
Also in my case as a bench supply for testing/running many things like my electroplating tank or motor testing.

And I will ask Shirley to sell me one, before the new year. I begin to favour one that is lying on its side, as I do knock things over quite a lot. But presumably these things can't be harmed by standing them up instead.

[Burgerman]

No. I use the upright ones (I have 2) on their side on my chairs seat cushions all the time. Thats why I wanted a sideways one! On your bench as a test power supply etc then upright is better as it saves space. On a chairs seat, sideways makes more sense. But if you dont care about the screen being the wrong way up either one works fine in both orientations. I you ignore the small feet and top handle. Which can be removed if preferred.



ZXD is £110
Shipping rate fast, adds 6kg -- £45

Or it was a week ago. Shirley will advise. Because some morons voted starmers marxists into power here and their recent rediculous budget just destroyed the £... So it will go up and up. Along with inflation, and interest rates. Because we no longer have any products made here as business cant afford the taxation, employment, net zero costs, or employees in the future etc.

Which considering its adjustable fully, and works better as a 3 stage charger alone than say a victron etc at 0 to 50A is still very cheap. And it can charge in addition, lithium, lead, or any chemistry needing 2 or 3 stage (user adjustable CC/CV/float or CC/CV), up to 60V then its rediculously cheap. And of course its a great power supply for powering hobby chargers too. A typical bench supply that is 1/4 of the capability is 4 £ figures minimum.

[biscuit]

Yes. Didn't think of that. Ends up as a big burden

[Burgerman]

Theres a new smaller upright one? With bigger screen.

[shirley_hkg]

What size is that barrel connector?

Should be 5.5x2.5

Will be included though.

[Burgerman]

I really like the actual knob on that new smaller one above. Can I get one of those? Just the top.

[shirley_hkg]

Just the top.

Don't quite get it ?

[Burgerman]

The bit you turn and press. Better on the new smaller ZXD. I would like one!

I like this knob.

For another project.

[shirley_hkg]

It depends on which fancy aluminum case you choose, or you can't hide the bottom of encoder and wires neatly.

[Burgerman]

I see.

Never mind.

[shirley_hkg]

You can take the upright version , with encoder in the centre, if you change mind.
I shall hold the shopping.
Let me know.

[Burgerman]

Does the smaller upright one above have the larger screen and an anderson or XT90 on rear?

If so I will take that one. Thanks!
ASAP!

[shirley_hkg]

I will take that one.

I'll get you the new upright version with bigger screen. Supply of aluminum case is tense, 10 days wait .
Rear panel has voltage sensor ports and IEC .
Will see if Anderson SB50 could be added to the rear as before.

[Burgerman]

Those pics dont show the larger screen?


Or XT90 is smaller? Anything thats safe for max power @ 50A regularly.

English obviously! I cant read chinese!
4mm bananas, or XT60 isnt really enough.

This one shows larger screen?

[shirley_hkg]

They have the same profile.
Look carefully. Big screen version has no room for LED indicator. Have to move downward, that leads to smaller air intake, and further induce to have extra intake on both sides.

They are XT90 and bilingual for sure.

[Burgerman]

Prefer large screen, old eyes! Both are good. Send whichever you want. Prefer quieter.

I'm also getting a second ZXD along with a couple of spare PL8's... It is great working with Shirley_hkg and figuring out all the many different variations there are... I wanted all the power connections other than the AC cord on the front, and he is setting me up with a configuration like I made with my original fancy case box from a few years ago...

It is a bit of an ugly hack, but I have banana jacks, an SB-50 and a PP45 pair accessible on the front side... Photos on other machine will add them in a bit...

For reference.

[Burgerman]

I think he has done that before...

[c500user]

I have been looking for a lab power supply with a bit more grunt than I now have. The ZXD certainly fits the bill and 60V is enough for what I plan to use it for (amplifier testing). The problem however is I usually need a symmetrical psu, so 2 independent rails of say 25V and -25V.

Some switching power supplies are totally isolated, so the output is truly floating. This means you can use one to provide 0V and 25V (black and red) and the other to provide -25V and 0V (black and red).
Power supplies that are not floating however, do not allow this, because you are connecting RED from one psu to BLACK from the other. If you do this with non-floating psus, expect some fireworks.

Is the output of the ZXD floating? If so, can you let me know the price for 2 units (HKD or EUR) + postage to Australia?

[Burgerman]

I think it is. Cant reach my fluke right now to find out for sure. On bed...

Anyone that can, connect the ground, earth, or chassis to the negative output and read off resistance. Should be very high.

I don't know about the new models, but my early ZXD with the original "fancy case" mod (installed by me) has three banana jacks, +, -, and ground. Per my meter with the supply off, + to ground is open loop, - to ground is about 5.8Mohm, and ground to case is 0, so it seems pretty well isolated...
