ZXD2400 modification guild 3Kw 0-60V 0-50A

[Burgerman]

While it was adjusted, and still dimming, she pressed the button! Dont do that. Wait for the dimming to go away. Then turn it. That then keeps the setting.

[Burgerman]

OK just had my ZXD passed to me on my bed!
Do as you did in the vid, choose your voltage, when it stops dimming then TURN the knob left (DO NOT PRESS IT) ... Now its set to your new settings and also stays whenever you power it up.

Mine was set to 20V and now set to 22V. Also was set to 40A and now set to 50A. Took seconds.

Dig your green nails...

[shirley_hkg]

Did you get only half of whatever the value you set ?

If so, self calibration failed. Prepare a piece of thick wire to short the output, and redo the self calibration again. (Turn it on, press 3 seconds to shut it down , then press 15 seconds to power it up and wait till you see the first left WHITE ZERO, follow the screen to finish .)

[Burgerman]

No, he is doing it incorrectly. Spent too much time doing his nails and not enough figuring out how to set it!

[shirley_hkg]

Hope you're right

[Gnomatic]

It needed re calibrated. Now behaving (and charging!) as I expect.

Thanks shirley for posting the instructions!

[Burgerman]

Really?
Mine does EXACTLY the same as yours does in the video. I tested it here on my bed to be sure.

But I can also set any current or voltage by waiting for the dimming to end and then turning the knob to any other parameter. Then it sticks and changes to whatever I set.

So I dont get it.

[Gnomatic]

Well, thanks for trying. It works now for me, so all good

As can I now!

[Gnomatic]

On my now recalibrated ZXD, I turn the knob till I get to voltage (or current) starts to blink. I press the button on the ZXD and it dims as you put it. Then I turn the knob to adjust to my desired voltage. Once there, I press the knob and it kicks me out to the main screen, with my desired voltage. Same if I'm now if I adjust current. That's how both my ZXD's behave.

It will. They all do. Mine does. Thats because you dont do that to save the setting. You TURN he knob instead once you wait and it stops dimming.

I tested EXACTLY what your wife showed. Mine did exactly the same thing. Then I did what I normally do, above and it saved the setting to match my chosen volts or amps correctly.

Recalibration has nothing to do with this. Your initial vid showed that yours behaved exactly the same as mine both do. Why would calibration change the way its programming code works? It might recalibrate it for better accuracy...

[shirley_hkg]

Turn to let the item you choose blink.
Press to select and it glows dim.
Turn to adjust .

PRESS TO STORE what you have set.

Only the Ah counter need no T to press to confirm . You let it exit by itself .

[Burgerman]

Press to store does not work on any of mine. IF they have been on for any length of time.
They behave exactly as the 1st video shows above.
I then just wait a while and then the selected value stops being "selected" then turn the knob either way to go to the next item. And that stores whatever you just set.

If it has just recently been turned on, it works exactly as shirley describes. I can set the figure I want, then press the button and it turns output off, and says OFF. But is still powered up and then turn the knob it turns on and displays the new voltage etc. So that also saved the new data. But this doese not work if its been on and powering something. If this is the case it behaves like the above paragraph.

So theres 2 ways. Depending on how long it was switched on. I never noticed this before. Or maybe its dependent on if you have 3 sae configured. I didnt test that.

[shirley_hkg]

It sounds weird, and unreasonable that operation varies as turn on time. I never have the experience you mentioned.

However , it does have 2 ways to operate.

1, Short press to select, and turn to change value. New value is NOT executed, till you press to confirm while it's still blinking. If not, it exits with no change of value.

2, LONG (1/2sec) press to select. Any change in value will be executed instantly (acts like ordinary bench supply). It will keep blinking, until you press to exist .

Both ways end with a PRESS of the encoder.

[Burgerman]

Mine behaves as you describe above if I recently turned it on.

But it does exactly the same as this if its been on a while and in use.

At which point you can get it to save (keep) the new setting by NOT pressing the button, but by rotating it left or right instead first.

I ALWAYS use press the button to store after I change the voltage, (or current) In the vid the ZXD is stuck 14.3v. I kept trying to change it to 28.2v. But it wouldn't "take" when I had the value I wanted when I saved it by pressing the button. It always was displaying 14.3v regardless. That's pretty clear in the vid to me.

Now, after recalibrating, I adjust the value, voltage in this case, and press the button to save it and it does! Just like my other one.

[Burgerman]

Yes. Mine both do that exact same thing as your video. AND sometimes can be saved by pressing as shown in your video too. It seems to depend on their mood. I dont think calibration has anything to do with the logic or the way they actually work. Theres a bug somewhere. The recalibration just thrown in a spanner that confuses this. It may well behave as you expected after calibration. But had you just tried again on a tuesday it would have done that too. Next time you see it doing that, try turning it instead and it will save the setting. And next time you try this after say restarting it it will behave just like it did after you did the recalibration thing. I suspect that the recalibrate is a bit like turning it off and back on again...

Calibrating should have nothing to do with the logic of the controls. Thats just the programmers C code.

[shirley_hkg]

Stock case model has XT-90 connector now, not only an alternative to Anderson SB50 but also slimmer and lighter.

@$1,200 HKD
10 days shipping hkd $360

[Burgerman]

Thats £156 UK inc shipping. HK Dollars scare me!

[shirley_hkg]

Spent quite some effort to find 4 brand new ZXD to feed members' appetite.

Now undergoing metamorphosis into 0-60V/0-50A adjustable.

[biscuit]

Do they run quietly, Shirley?

[shirley_hkg]

No.

The new generation with colour display is much quieter, but it don't have English menu till 2024.

[shirley_hkg]

[Burgerman]

But none of us other than you can speak chinese/HKese so we cant buy them!

[shirley_hkg]

No. These 4 are old version , the same as your's.

It has XT90, instead of Andersen SB50, and no fency aluminum outfit so it is more compact and 1.8 kg lighter.

New breed has large LCD display. Don't mix up.

[Burgerman]

But I cant read it! Chinesium.

[daveonwheels]

no. its pu tong hua. common people's speech. with simplified characters

Hi,

My ZDX2400 Power supply has suddenly failed in that there is no output voltage from it. The last time I used it was about 3 weeks back and was working perfectly.
I had set the voltage at 30v and current 40amp. I am left with no power supply now. Any inputs to solve the problem is highly appreciated. Thanks.

[Burgerman]

Very strange. They seem to be bomb proof. Shirley will be able to tell you how to "reset" it. Does it turn on? Can you set anything?
