I'm interested in modifying server power supply to output 13.8V but often the overvoltage protection will activate and shutdown the supply. There are methods these can be changed and I was successful in doing so. I have shared my findings on EEVblog and offered help for others members too.

Today, upon searching for DNA1006, an ASIC IC often found in these power supplies, I came across a post on the (数码之家)mydigit.cn forum of a guy successfully bypassed the OVP and the DNA1006. He also kindly detailed his findings in a post on that website. Unfortunately, though mydigit.cn is a public electronic forum located in China and free registration is open to everyone, they are meant for local people with a Chinese cell phone number. Without registration, images are shown in thumbnail size only. I tried to register but as I'm not physically located inside Mainland, the registration failed.

All I'm interested are the eight images of the first post in the following thread which detailed how the OVP is being modified. If any one can help to get those images, I would be deeply grateful for your kind effort. You can either provide a download link, attached them as reply to this thread, PM me a download link or send to my email address.

The following is the link to the forum post.

我有兴趣将服务器电源修改为输出 13.8V,但过压保护通常会激活并关闭电源。有一些方法可以改变这些,我成功地做到了,然后我在 EEVblog 上分享了我的发现,并为其他成员提供了帮助。

今天,在搜索特定的ASIC DNA1006时,我在(数码之家)digital.cn论坛上看到一个人成功绕过了OVP和DNA1006的帖子。他还亲切地在该网站上的一篇文章中详细介绍了他的发现。不幸的是,虽然 mydigit.cn 是一个位于中国的公共电子论坛,并且向所有人开放注册,但它们是为拥有中国手机号的当地人准备的。未经注册,图像仅以缩略图大小显示。我尝试注册,但由于我不在大陆境内,所以手机号注册失败。

我感兴趣的是帖子中第一篇回复的八张图片,其中详细说明了如何修改 OVP。如果有人可以提供帮助,我将非常感谢您的善意努力。你可以上传它们作为对这个帖子的回复或私信我一个下载链接或发送到我的电子邮箱

Thanks a lot for your help. I have re-posted the images adding english description so that other members can understand how the mod is being done. It was about the DELL server power supply 670W, 12V 54.4A and 3.3V 5.25A. The exact model number is not known but I have attached one image about the external and internal of the PS.

I was hoping the hand drawn schematic is about the DNA1006 IC but it turns out to be the UCC3895D PWM controller instead. Looks like the quest for information on this DNA1006 IC continues.

Digital Home, the author modified this power supply into a power supply that can adjust the voltage output.
The author could not find any information on the DNA1006 IC, and finally disconnected the processing of this chip.
Digital Home is a well-known DIY forum in China, I am one of them, looking forward to communicating with you ;D

You can register wechat account first, then use it to login to that forum.
Or you can register QQ account.

Hi there,

I don't want to open a new thread about the same thing, which is essentially accessing mydigit.cn forum.

I'm missing one schematics image from this thread:

https://www.mydigit.cn/thread-369594-1-1.html

The second screenshot of a datasheet of some known to nobody "color driver chip JXC0905B" I would like to get.

Could someone help me to grab the second datasheet image from that linked forum thread, please?

I've tried to register on QQ or WeChat but neither let me finish the process without having some friend with it which in my social group is nobody1.

1. Well, I know a good seller in a local market, but I don't think they put themselves in a risk of some glorious punishment of themselves and their family if something went wrong.

Thank you!
Freedom to knowledge |O

That forum contains a lot of useful info, especially the datasheets for some chinese chips, not available elsewhere - I even had to invest into Chinese SIM card, to get access to it to be able to post :)

"Battery Management Studio (BQstudio) "needs to be downloaded separately because it is too large.
