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

[martin007]

I have more patience than money ...
I can wait a month (or more).

[Gnomatic]

I've been waiting for some ring terminals and other odds and ends to arrive before fitting the fancy case. The supply has been out of the old case since last week. I wish I had taken pictures as I took the old case apart. Because now I'm trying to figure out which of the DC power output on the board is + and which is - before connecting the ring terminals.

[Burgerman]

I did the same. I powered it up, the terminal nearest the red wire that goes to the glass bulb is pos...

[Gnomatic]

ok, so pos is the one next to where the red wire is soldered to the board ...

[Burgerman]

From memory, yes. If I am wrong, then oops. I dont think I am.

As long as the wires are not added to the anderson yet, or connected to the front panel, its not that much of a problem. Since you can swap over.

The other thing is this. IN CASE I was wrong, I had swapped the two screws for hex head ones. So a small spanner could be used after assembly to swap over. By removing just the end. But I was correct since I decided to check on my meter before I got it wrong!

[Gnomatic]

Thank you. Next up, figuring out the polarity of the AC inputs on the opposite side of the psu .....

You hinted your age .

Marks are on PCB.

[shirley_hkg]

Could you send me a charger shirley_hkg?


You send me (PM) the amount and the Paypal address.
I can send you the money as a Friend and thus Paypal does not charge commissions.

Just closed and checkout with 2 psu this monday . Not yet collected .

Will let you know when the next purchase begins .

[Gnomatic]

Thanks shirley LOL. I'll get this up and running soon enough.

[Burgerman]

Its AC. It has no polarity. Its both. Any way around.

OK.

[Burgerman]

Anyone know where that translation link is?

Cant fathom this hidden settings for charge setting by guesswork

Been testing as a 3 stage charger.
I set to suit grp24 MK gel. So:

In the complicated menu 9. (fortunately only needs configuring once) I enabled the 3 STAGE CHARGE only. Everything else left alone. Trust me you can get in a mess testing these things! Then, press twice in number 5. on save.

I set a charge Amps of 12A (for XLR plug)
I set a CV voltage (Charge Voltage) of 28.2V
I set a termination current - where it goes to Float - of 0.2A
I set a FLOAT voltage of 27.2 since this completes the charge faster. (set a 26.8V for long term storage, 27V for a few weeks max)

Result? Exactly what it says on the tin. Works perfectly. Makes an ideal overnight charger, via the XLR plug, or if you use an anderson at much higher currents like 25, for normal use, or up to 50 in doing sport or whatever and in a hurry. And it remembers the settings.

Two things. Engineer/setup menu...
The ENGLISH instructions must be read 20 times, with some head scratching. Because its not clear what each function does. Use care, change one thing at a time. Its not exactly intuitive. User menu quite simple but takes a while to figure out.
The fan is noisy. At least mine is. I didnt think so at first, since I have so many other things with fans in the day that I wasnt really audible. But at night you may want to use a long (4mm?) cable and hide it somewhere out of the way. Personally fans dont bother me. Because ...

[martin007]

Great news.

[steves1977uk]

This PSU isn't much bigger than your typical 8 Amp toaster style charger, yet approx 14.29 times more powerful and can be set correctly to the battery specs!

Steve

[Gnomatic]

Thats awesome BM. Set up like that makes it miles better or a least miles more consistent than standard mobility chargers .

[Burgerman]

And 50% more powerful even by XLR plug.

Whats more, once powered up, (press and wait) it literally just needs plugging into the chair by anderson, or by XLR and away you go. Foolproof for those with carers. But its a bit noisy.

Youcan configure it to 40 or even 50A CC stage, 29.4V CV stage, and to 0.2A termination, with 13.6V float for Odyssey. As well. Or same thing and 14.5V for generic AGMs.
So it can correctly charge all, with a few changes of setings. At the price it is its stupidly cheap for a 3kw charger! And the only downside is the complex menu... Its still giving me a headache. A better translation with more detail would help. At that price get em while they are about. Soon this over production run charger/power supply will disapear most likely.

[martin007]

We are waiting for shirley_hkg to place a new order.

I want (when the charger arrives) to make a PDF user manual.

[shirley_hkg]

NO RUSH !

Wait till BM's ultimate user review , to see if it is a good pick . 一

That's a great user review . Thanks John .

So , go get them .

I will get another new one as collection .

[Burgerman]

For those that think its hard for a carer to use.
Once configured...

Watch. Shows a fully charged chair being charged. So CV and Float stage.

Can you purchase this already done - ? with no user effort ?

[Burgerman]

Yes, but not in the fancy case.

[Burgerman]

Yes, but not in the fancy case.

[expresso]

meaning theres nothing a user has to do - just turn it on and use it ? besides to figure out the manual if not english

[Burgerman]

Wel it might take you a couple of hours to figure out how. After that its plug and play. No good for lithium.

After that, just turn on, plug in... Done.

[expresso]

oh i see - just a Lead charger etc, ? i am almost off lead - working on lithium for all my chairs at least the out door ones and ADD On for any other

Its main function is a powerful and adjustable PSU. I will pick one too once I get ... PRO . Now still being happy with a modest 12v psu

[shirley_hkg]

. No good for lithium.
.

Why is that ? Not good to power PL8 ?

[Burgerman]

Because it doesent balance cells WITHOUT a PL8. Expresso thought it did, I think.
