[Burgerman]

Here too, firefox on windows. As normal, working as before.

Just set up my ZXD2400 in 3 stage charge mode to charge my Dietz chair batteries better.

Shirley, any chance of buying another couple of these PSUs please? A cased one would be preferred but a stock one would be ok too.

Steve

[shirley_hkg]

Have to source a new seller .

[shirley_hkg]

More choices now , with extra built-in XT_90 connector . .

[steves1977uk]

What's the price of them now Shirley? I quite like the wider one with the XT90 at the back. Do any of the sellers offer an Anderson SB50 connector?

I have looked for a Chinese seller in the European Union, but I can't find any...

[Burgerman]

That whole sentence is chinese...

You said it.
I don't want to be robbed with the customs tax.

[Burgerman]

So far I was never caught. Its coming from HK and that used to be british and so I think they dont bother even looking to see whats what. Never been charged customs from HK and only once from china. And I do quite a few things yearly. US? Every time!

You don't live in a socialist country.
In Spain they will charge for breathing...
...CO2 is bad.

In June they will start billing the electricity by hourly sections.
Do you know what hours will be the most expensive?
Spain is ruled by sons of bi*****.

[Burgerman]

Let me guess. When its needed the most? Like when you need heat, cook, etc?

Thats so that they force you to use the high demand stuff like dryers or heaters at night when everyone is asleep. Its cheaper than having enough power station generating capability. And god forbid you create some C02.

[expresso]

thats also here in the states


peak times cost more - same thing here - depends on the cost also - per kilowatt etc,

Yes.

I've found a minor annoyance - the binder post banana jacks on the ZDX are not compatible with the "Safety" banana plugs we use on the PL8... I like the safety plugs and have cables I made for the PL-8 that I'd like to use w/ the ZDX, but they don't fit

Any source for banana jacks that are compatible w/ the safety plugs?

ex-Gooserider

[Burgerman]

Seen them on ebay. But bannana's are no good on the PL8 INPUT as that can pull 70A if charging in a vehicle for e.g. Or 55A if charging at full power from a 24V supply. Which is why mine all have anderson 50s on them. As do all my chairs, power supplies, van, tools, inverters, bed, and more.

[ex-Gooserider]

I don't use bananas on the input side of the PL8, but it does use them on the OUTPUT side.... I made a charger cable to go between the PL8 and the chair so I had to use the safety banana plugs to connect to the PL8... Now I can't plug that cable into the ZXD... I need some jacks that will accept the safety bananas so that I can make an adapter for the ZXD that will let me use the same cable with either the PL8 or the ZXD.

Will see what I can find on fleabay...

ex-Gooserider

[Burgerman]

Since the ZXD can do 50A and bananas are nut sefe at that level, just fit an anderson on the rear. Easy and a safe way to take advantage of its power.

These are available, in many colours. No idea of quality. https://www.ebay.com/itm/152615033052

[ex-Gooserider]

Back when I was doing the initial build, I put both an SB-50 and a pair of PP-15/30/45's on the ZXD, so that wasn't the issue. The problem is the CABLE I'd made that had "safety bananas" so it would plug into the PL8.

I've now solved it, I took a spare stackable dual banana plug/jack fitting that also had a place to attach wires to it, and put a pair of AWG 16 wires a foot or so long and going to a air of PP-15/30/45's. The safety bananas I used are stackable, so I can plug the male ends of the fitting into the back of the safety bananas and then plug the PP's into the ZXD. This gives me a safe (no exposed conductor) connection w/o doing any other mods.

(Another annoyance is the non-standard spacing on the ZXD fancy case banana jacks...)

Of course, after I made the adapter cable I found a pair of safety banana jacks in one of my boxes of parts, but will save those for some other project now.

A little nervous about all this...When holding the encoder for 3 seconds after startup I get the "FACTORY n.NODE" msg and then it takes off throwing a bunch of codes at me finally resting on the "PLEASE SHORT CIRCUIT" msg. I need to have a load on it to enter the menu system? This was the best instruction I have found...if there is a better link pls provide. I should make a video how to use this if i ever figure it out.

Instruction turned from shirley english to my english so I dont get a headache!

INSTRUCTION, MENU, OPERATION
It has quite some useful features apart from just a 0-60V / 0-50A CC/CV power supply.

Hold the encoder button 3 sec on power up will enter this mode:
http://diy.lgm3361.com/zxd2400/3/annex2/

Factory menu locked.
To enter: Press "3 seconds" during power up, and enter code "00088".

1, manual calibration of 3V
2, manual calibration of 19-60V
3, manual calibration of 1A
4, manual calibration of 9-50A
5, SAVE adjustment and leave
6, LEAVE without saving
7, Reset to factory setting (dont, not sure what this will do!)
8, OVER Volt & Amp output protection ; with user adjustable criteria (Set max Amps, 30V for PL8 for safe operation)
9, explained below***

A, 0.1 or 0.01 display of the V&A
B, EMPTY?
C, Version of kit
D, reserved for examination
E, EEPRM decimal
F, EEPRM hexadecimal

No 9*** for the HIDE/ON of the features below. 7 zeros for 7 features; ZERO on top (first digit on display) is ON, bottom is HIDE.

1, nine preset profiles allowed (Useful for setting different battery or power supply profiles)
2, lock menu (not sure what that does?)
3, auto output at power up (not sure what that does either yet?)
4, auto power up at MAIN on (not sure what that does? Again!)
5, a 3-stage charger; with adjustable residual current that trickles to float, and float voltage as well
http://diy.lgm3361.com/zxd2400/3/annex1/1/
Default settings of residual current and float volt are 30% and 93% respectively (with MAX cap at bulk charge values). Too soon for lead cyclic batteries. But can be adjusted.

6, display of present & last session Ah delivered
7, auto shut down; when output is lower than user prescribed amps.

Operation tips:
On "short press" to select volt / amp adjustment , new value will become active when press encoder again.
If press/hold 1 second instead of just a short press , adjustment will be INSTANT!

[Arima]

I guess I am in the menu already after 3 second hold on powerup. It is asking me for a 3v ref voktage. I need to input 3 volts at the banana plugs? Then press the encoder to calibrate against the 3 volts?

[Arima]

Think I'm getting thru the menu better...I have version 3.18....hope that is not a show stopper. Went thru the links on the modification page translation and see and see that option #1 - manual calibration of 3 has a value of 01617. On my box the value is 01715. Not sure if I need worry about this? I should be able to set the voltage and measure it with a multimeter. Do not understand the why this menu setting exist

[Burgerman]

Just measure what it does. Mine was pretty close so never touched it.

[LROBBINS]

My experience is that the auto calibration is at least as accurate as my cheap voltmeter.

[Burgerman]

Theres also this. As the load increases the voltage also increases by a small percentage. On purpose to account for cable resistance etc. So dont stress it.

Many cheap or even medium volt meters are not particularly accurate. My "cheap" fluke meter reads both high and low by a little depending on scale, amps or volts or resistance etc. Also by actual voltage. Can be right at 3v and miles out at 30V. It also depends on how much ripple, noise, AC component there is on the DC voltage. So I would go with the auto calibration. Unless you can measure and I mean details.

*compared to the fancy calibrated certified Fluke 289 I also have. It gets sent in for calibration every couple of years.

[shirley_hkg]

Found one wih both XT90 & Anderson SB50 installed . HKD $2,000 free shipping .

Let me know.

[Arima]

The free shipping would have saved me a couple bucks. Someone should jump on this!

[Burgerman]

Interestingly the second photo is of my actual unit that I did here myself. And I sell nothing.

[shirley_hkg]

I borrowed your photo.
