But they are clever. They hold your parcel ransom till you pay. Unlike EVERY OTHER COMPANY who deliver the parcel ASAP and bill you later. I DETEST parcel Farce.

Amen to that

Agreed, but what can you do?

Knowing my luck, if SM challenged it, I'd get a bill for £7.78!

The 3rd UK one hasn't been delivered yet. Want to take bets on its charges being bigger or smaller?

Its not the actual charges that bother me, but the way the parcel farce work. And hold you ransom. And charge you to deliver something you already paid for.

It was intuitive because its basically exactly the same as the Tenma 30-0-30v 10A 4-channel bench supply I have! Now I have to decide what to do with the big Digimess 3050 supply..

Interestingly that display/daughter board has clearly been designed by someone for this purpose - and it has a serial interface to the STM micro-controller that does all the UI. Add an HC05 BlueTooth adaptor and some tweaks to the s/w (unless already done) and you've got remote control/monitoring!

Yes, its an addon to the fixed voltage telecoms power supply to make it adjustable Current, or volts. Or a configurable 3 stage charger.

I use it as a charger set as CC/CV power supply though. Just set for gel, 28.0V and leave it 8 to 10 hours, at 12A (XLR) or 25A / 35A anderson... Until current drops to a really low .1A or so. IF it starts to increase, turn it off, or/and lower voltage.

Excellent piece of hardware though some mounting holes would have been good. If I can be assed, next time I open the box, I might 3D print a clippy thing to glue to the front panel and hold it in place.

Haven't found any details of it on web yet though.

Another thought - the date codes on some of the devices in there suggest either 2005 or 2015 manufacture. If it is 2005 (and the online docs for the original "telecom rectifier" as translated are dated 2005) then some of the chunky electrolytic capacitors may be approaching EOL. I could be wrong re dates, I hope so, but something to be aware of.

Checking the tracking ref on Parcelforce.com shows its still awaiting customs clearance. It could be yours is unlucky to be have been picked for customs examination and they do say there's a backlog at the moment. I know mine wasn't opened by customs and I'm guessing Scooterman's likewise looking at his picture of the box.

You could try calling PF but if it's in Customs there's little they can do.

Hi Irving thanks for the update.
I see that you have been able to check on the packages
how did you manage to check with PF about the them
and is there a reference that I need if I call them, or can
I check online.

This post, 2 pages back, gives the HK reference. Put that in the PF tracker and it will reveal all including the matching PF ref.

I got a bit confused by your link as it sent me to page 3, but found the tracking number on page 35.
As you have said it looks like it is still with customs, oh well i will hopefull be contacted sometime thanks.

Just been back on the PF site using the tracking number that they gave for my package
and can see that they have my address down but with my house number missing.
I wonder if this is the reason for them not contacting me.

Ah, bug in Board (phpBB) software. I have my view set to latest post first, I guess yours is set to 'normal' date order, so it fails to adjust for sort order.

Hi yes I gave them a call and spoke to a helpful lady.
She said that she didn’t think that it would be address problem.
Although she couldn’t be sure as the parcel as we thought was still with customs.

There is a time limit before having to release the parcel which is next Tuesday and
If I have not heard from them then to call back at the end of the week and she will
be able to look Into it.

Hi all just received my package at last from PF thanks very much Shirley looks to have travelled well.
Just the handle a bit bent but i can replace that and so far no messages from customs.
I just need to hunt up a kettle lead fire it up and find out how to use it.

Hello Shirley, yes the handle is no problem I can soon sort that, you made a very good job of the packing it worked well.
I now just have to sort out how to program it especially for the 3 stage charging, also should I check regarding calibration.

Calibration on mine was damned near spot on. It will increase volts marginally on load, its meant to...

Also, while it can do 3 stage. If you are overnight charging, all you really need do is set Amps, and then volts as a power supply. Just dont leave it longer than 8 hours CV. So bed at 12 midnight. Then a few hours charging CC, plus approx 8 hours. If current falls to sod all, .1 or less, its done. If you do leave it a little longer now and again it wort hurt, just lower volts by say .3V for 12 hours, or to 2x 13.8 for 2 days, 13.6 for up to a week, 13.35 indefinitely. Keeps it desulfated.

It just means you dont need reset it to use as a power supply for PL8 or whatever. Right now mines plating hit and miss engine parts in nickel!

Hi BM yes I think that I will take your advice and try to just use as a power supply.
I am going to print out the online Google translation manual for the ZXD2400 to have to hand, i have read through it
online but at present it has gone over my head.
I also need to read through the forum and find how to setup the CC/CV charging settings for my Odyssey batteries
with the power supply.

Postby shirley_hkg » 31 Oct 2019, 02:52

and this invaluable piece, in particular, by LORBBINS, as it is beyond your manual that you shouldn't miss.

LROBBINS wrote: I think that I now have this supply mostly set up as I want it, so I thought I'd share my settings in case they're of use to others. Aside from use as a bench supply, the main use will be for charging series-paired Odyssey P1500 batteries. So my first step was to go to Figure 5 of the Odyssey technical manual to see what voltages they recommend:

temp. -- Vcv -- Vfloat
20oC -- 29.7 -- 27.5
25oC -- 29.4 -- 27.3
30oC -- 29.2 -- 27.1 (for typical summer days here, this is what I've set)
40oC -- 28.8 -- 26.8

With out a Vcv timer, Odyssey recommends switching to float at 0.1C10, which is 0.63A which seemed to me excessive. Burgerman suggests a more reasonable 0.2A, but I found that with a pair of old, almost fully-charged batteries current didn't fall to 0.2A after 8 hours, but fell to 0.3A in about two hours with Vcv = 29.2 at a room temp of ca. 28oC, so that's what I've set.

So, now on to setting up the supply:
The Eprom values (factory menu E) were set for my situation. I foresee rarely if ever needing more than 30V output, nor more than 30A so I set:
Eprom address --- Value
52 --- 3000 (= 30 V maximum allowed setting)
53 --- 3000 (= 30 A maximum allowed setting)
3-stage charger float voltage and transition current are set as thousandths of the base voltage and current settings:
Eprom address --- Value
73 --- left at default 930 which is 93% of CV voltage and very close to Odyssey's recommendations
74 --- 10 (this is 1% of base Amps setting, = 0.3A)
As others have noted, the stock fans are annoyingly loud. Not having appropriate resistors on hand, but having a large stock of 5Amp Schottkeys, I put 4 Schottkeys (with matching male & female connectors) into each fan line. This reduced the noise noticeably at low fan speed, but at low currents and with the shop at ca. 30oC it went to high speed at currents less than 1 Amp even, and that was still quite noisy. I therefore raised the transition temp a bit:
Eprom address --- Value
50 --- 55 (up to 55o from the default 50o)
and I added some Arctic silver between the heat sink and the left side plate of the case. The fan still gets pretty noisy at float, when the room temp is 30o, but stays relatively quiet at room temp = 25o and the outlet air is cold and the side plate barely warm. I think I could safely raise the transition temp to 60o, but will wait till I have some more experience with this.

At one point in all my fiddling things went quite strange - output voltage and current were about 1/2 of the set values, so I re-did the auto-calibration. To do that you have to get rid of the "88" password that had been set, then shut off the power supply with the push button and re-start holding the button pressed for ca. 15 seconds. (No sense for me to attempt a manual calibration as my multimeter is un-calibrated.)
Eprom address --- Value
99 --- 0 (changed from 88, and I've left it at 0 = no password so a 3 second long turn-on press brings me right to the factory menu without entering the 88)
The instructions for auto calibration in the user's manual are pretty clear - you just need to short the output when it says to, and then remove the short when it says to do that, and don't press the encoder during the rest of the multi-step sequence.

Once (with some help from Burgerman) I got used to the (translated) manuals, I found them reasonably easy to follow. I have, however, not yet set over voltage and over current values (factory menu 8). These are to protect from runaway failures of the power supply electronics and I will probably set them once I've experimented a bit to find reasonable values that don't give false errors (especially when used with motor loads than can regeneration-pulse voltages over the set voltage).

One last thing. At one point I had the front panel open with the supply unplugged but battery still connected (bad boy!) and shorted B+ to the case. I now have a nice (but hidden when buttoned up) burn mark on the case. A piece of tape is now on the case by those banana jacks. Oh yes, I also drilled a 2.5mm hole in the front fan surround and added a cable tie to stress-relieve the display/control wiring.

Ta very much! And you cropped/edited that horrible twin and earth cable :thumbup:

TWO because I had to refer to the one I did previously. Although gawd knows why as it's simple enough, just a bit fiddly and lots of little screws. It was so much easier with the pre-cut cutout for the Anderson.

I charge at 36A, and most of the time during charge lithium sits at about 3.3V so gives 3.3 x 8 x 36 = 950W

PL8 and PSU aren't 100% efficient so PSU probably draws what, 1100-1200W

So charging 8S lifepo4 at 36A the ZXD2400 is only running at 50% max capability?

Which is fine, I don't want to charge at higher rate.
