VIELEN DANK! Ich habe gerade die beiden erhalten, die ich vor ein paar Wochen gekauft habe.
Ich habe das Handbuch im Voraus gelesen, aber ich habe nicht bemerkt, dass auch bei den APS-Modellen "Optional" steht.
Ich werde es öffnen und sehen, ob es die gleichen Verbindungen hat, DANKE!
Many thanks for posting this!
I have already soldered the header on the control board of my Wanptek APS605H. On that model, the lower communications port solder pads are oriented horizontally instead of vertically. The rest is the same.
I recycled a 4 pin JST PH (2.0mm pitch) socket with pins and a male connector with wires from a dead PC power supply and mounted the socket and its pins on the control board. I like the JST socket because it is keyed, and so can't be inserted backwards.
I didn't have the USB type-2 female connector or the ttl to usb adapter on hand so I located and ordered a USB type-2 female bulkhead mount to micro usb 30cm cable and a CP2102 MICRO USB to UART TTL 6 pin Module from Aliexpress to complete the project. Total cost was $5.17 USD.
The project is on hold for a couple of weeks until the parts arrive. I already have the usb type-2 male to usb type-1 A cable that I'll use to connect the power supply to the computer from an old printer that's long been recycled.
Here are links to these parts:

Hello, did anyone find a workaround for the new motherboards?
Did you see the word document in their download site? It is in Chinese, but it can be translated by Microsoft Word. It contains a detailed description of the communications protocol for communicating with their power supplies. It also mentions that the "program" they have is just a demo -- there are no advanced functions available. it just duplicates the controls on the power supply.
So my question is; has anyone found a program that can do more interesting things with the power supply -- like setting a timer for the power supply once the output voltage rises to the set threshold and the amps start dropping so that it doesn't cook batteries.
Great stuff here, thanks.
By any chance do you know if APS-3010H has any requirement for this?
I found the 4 pins at the bottom, and was easy to identify the GND,TX and RX. I've tried may USB-serial converters without luck.
Even tried to use another 4 pins more on the top, but also no luck.
I wonder if they've disabled somehow in the firmware
Hi, I don't think they've disabled it in the firmware. According to the manual you can set a "Native ID" which has to correspond with the ID set in the Software. Maybe the boud rate is different or the endian is wrong. Both can also be set in the PSU settings.
I guess you have installed the driver for your converter and selected the right Port in the Software.
@@techlike49 I confirmed the baud rates, the Indian stuff I've also tweaked, but no luck, I tried with that little ch340 programmer, with an rs485 adapter, but nothing... I'll review soldering again
if possible can you tell me if your board had a 10k resistor between vcc and RX line? thanks
@pfmc Hi, did You found a solution on this?
Hello! Could you send a photo of the board with the component values?
Hello. I opened recently a WPS3010H and instead of the header on the board there were 5 contact holes with in the vicinity a microcontroller with serial port. I connected the right contacts to the USB converter but there was no communication to and from the power supply. The USB converter works correctly with a terminal program (like Putty). Did you install this file "CH341SER（CH340串口驱动 ）.EXE" ? Comes with the download of the software. Does this file take part in the communication you think? I tried to install it but the installation fails.
Hi. The CH340 is a USB to Serial Chip. Depending on the USB converter you are using it has the ch340/ch341 or a different chip. You need the right driver for it and then it should work. I used a ch340 but got the driver from its manufacturer homage and didn't installed the exe from wanptek.
@@techlike49 Ok, thanks for clearing that up. I use the FT232 so no need for the exe.
great hack! :)
Cool!
Hello, the cartoon was very beautiful and tasteful. I have just one question, can you use bluetooth module instead of ttl? I mean, if our interface is Bluetooth, with a computer instead of a USB port, I would appreciate it if you answer. Excuse me, I wrote to England. I am from Iran and I love the people of your country very much, and all our people are like this.
Do you have link to USB to serial converter that is premade?
Unfortunately I can’d find one with a USB Type B connector which would fit. But this one should work just fine: s.click.aliexpress.com/e/_DlNfdmJ
and this is the one I showed in the Video: s.click.aliexpress.com/e/_DlggCEx
Hi bei mir hat das netzeil keine seriell oder ttl anschlüsse sondern pins mit der beschriftung "R D G S V" sind 5 pins, ist das auch seriell und wo müsste ich die kabel dann anschlißen
Hi, wie in den anderen Kommentaren bereits diskutiert scheint es eine neue Version des PCBs zu geben. Bei der neuen Version fehlt die serielle Schnittstelle. Die von dir genannten Pins sind nicht serielle. Zumindest weiß noch keiner wie man mit diesem interagieren kann.
R --> Reset
D --> TX
G --> Ground
S --> RX
V --> VDD
@@Potalak Die pads gehen tatsächlich zum UART1 des controllers werden aber bei dieser firmware nicht benutzt und daher unbrauchbar!
@@gogoaccount7873 Könnte man eventuell eine editierte FW flashen?
I have the same problem as others in the comments, my board has 5 holes labelled R-D-G-S-V. I have tried to interface with it but with no success, there seems to be no response from the power supply. Has anyone had any success with this board?
yes the version is v1.0 with the date 2022-06-20?
@@omerh1625 yes that’s it
@@josephinring what i have seen all of pins goes to the MS51FB9AE Microcontroller chip (R - pin 4 nRESET, D - pin 8 UART1-TXD, G - pin 7 VSS, S - pin 18 UART1_RXD, V - pin 9 VDD). i have checked with my scope the transmission line (pin 8) and i didnt get any response from it
@@omerh1625 yeah I had the same problem, for some reason there is no response from the controller.
@@omerh1625 Same here - Board Rev 2022-06-20 - R D G S V Pinout - There's no serial bus attached to the pins. I think they disabled the serial bus via firmware. Or there may be a hidden menu where we can enable the serial output, but by default it's switched off.
Downloaded app from your link... but my interface have chinnese language.... how can i chage to english?
Right click on the background and choose English
Where to find the software to download? The wanptek powersupply pc console
You can find it at Wanpteks Website. I have linked it in the description.
@@techlike49 sorry didnt see that, much thanks
Any chance this would work for the TPS3010 model?
In theory it could be possible. It looks like the old ones but just orientated differently but many viewers have commented that wanptek removed the pins on newer revision which probably includes your one. So it's unlikely it will work that easy.
@@techlike49 OK, thanks!
@@techlike49 Just opened mine for a peek to confirm. As expected, the pins were missing. However, I’ve found five unused headless pins (no header was soldered to it) labeled V S G D R respectively. I have no idea what there purpose is; but if anyone knows & its of any help, I’d love to know 😀
Some info - the internal PCB of an APS605H looks different. There is no such possibility to connect such an interface. At least at mine from June 2022.
That's weird! According to the manufacturers website and datasheet this model can support USB host as well (optional). Maybe the pins are at a different location on the PCB?
Yeah I know, as the manual describes this option... I didn't disassembled it completely, just looked at the backside of the PCB. Maybe the solder joints of the front USB can be used but I can't imagine that they just use them without dedicated pins... The housing has already the USB cutout at the backside like in the video. Maybe I just try to connect via front USB...
same as mine, i have just opened it and got a different hardware (for the WPS3010H).
There are a set of four header holes that are aligned horizontally on the lower left side of the APS605H control board. That is where you need to solder your header. They are there -- I just completed soldering a recycled JST PH (2mm spacing) 4 pin socket with pins on the control board that I got from a dead HP workstation power supply. I also took the mating male connector and its wires to connect to the ttl to USB adapter I ordered from Aliexpress.
See my note above for links to the that adapter board and the USB type 2 female cable assembly I ordered.
Just noticed this comment after posting mine. My WSP305H has the new, downgraded board. In theory, the 5-pin programming connector with pins labeled RDGSV could be used for communication, as it outputs the MCU's UART pins. The problem is the firmware for the new board does not support remote control. The comm settings are present in the menu but they are not used. Pity that the nice unit was downgraded this way. I tried to talk to Wanptek store person - they simply say that they don't support remote control in units not already supplied with USB interface in factory. My plan was to mount USB-C UART module in a 3D-printed bracket. I already designed the bracket and made a proper English translation of Wanptek comm protocol description only to realize that I will have no chance to use it.
Need dc sweep
Nice hack but disappointed to discover that it will no longer work on my newer PSU 😞
hello thank you for your video.
can you upload their program (zip) and the programmable file in here?
Hi, I didn't notice the change of the URL. I updated the Software Download link in the description.
@@techlike49 the english version please
This is the English version. Open the program, just right-click on the background, and choose English.
😊
The upgrade is no longer possible with the current mainboard used in WPS305H. Seems like the vendor decided so save 5 cents and made a new board with the new firmware, based on 20-pin Nuvoton 51 clone. There is no official information on the board being degraded that way. There is no comm connector onboard, the MCU programming connector outputs RXD and TXD lines but the firmware does not allow for communication any more. The firmware has the comm-related settings in the menu but they don't work and the speed setting is not stored (that's a method of recognizing that you have the new, "optimized" unit - try to change it from default 1 to any other value, save, turn on and off, enter the menu, it stays at 1). Not a single word was changed in the manual which describes the unit as capable of remote control. Really bad move by Wanptek.
I can confirm that upgrade is not possible on the newest boards 😢.
Hi, maybe someone can make a reverse engineering on that unit to hack it. My WPS3010H is on the way...
I just bought WPS3010H with board:
WT300-PCWU-PC2-WPS
2023-04-27
V1.1
Same problem, after turn off and back on speed setting (communication baud rate) is not stored. I don't even bother to buy any rs232 interface...
BAD MOVE WANPTEK!
Will it do constant voltage and constant current? Ta
Yes. CV is standard but if your draw more power than you set it changes to CC or shuts off, depending on your settings.
ttl conversor for easy instalation!
The music for sure does not make this video better (or easier to listen to)!
I am having a little fight with the Aliexpress seller, he wants to sell me the same power supply but with the integrated usb host for double the money, he says that they can only leave the factory with the integrated usb host module. The module needed to do the installation rs232/485 is described on the official page and in the user manual. I think the seller is wrong and I will prove it to him. The psu cost me 74€ from aliexpress send from Spain to Spain fast shipping 2-5 days received.
So? Did you manage to prove him wrong?
Hi are you still happy with Power Supply?
Yes, absolutely. It offers so much power and functions for a really low price. It does it's job just fine, so I can't complain. But keep in mind that the upgrade might not be possible anymore :/
@@techlike49 Thanks.
@@techlike49 why might it not possible? On their website they claim an "optional USB host interface" on APS and WPS devices. Do ypu know if this is possible with the TPS series as well?
@@Knochi77 They claim it, but according to other comments, Wanptek removed the internal pins/removed the USB function from the source code. So, depending on the version you got, it is / isn't possible.
Looks like the TPS Series is pretty new. In theory, it could be upgradeable, but I highly doubt it due to the removal on older models.
